The technical field to which the invention relates

The invention relates in General to lighting devices. In particular, disclosed herein of various patentable methods and apparatus relate to lighting devices configured for messages about the anomalies in their work through lighting effects, as well as to relevant systems coded warnings.

The level of technology

Digital lighting technology, i.e., light-based semiconductor light sources such as light emitting diodes (LED), offer a feasible alternative to traditional fluorescent lamps, gas discharge lamps high intensity discharge (HID) and incandescent lamps. Functional advantages and benefits of using LED include high optical efficiency and high optical power, durability, lower operating costs and more. Recent promising developments in LED technology have provided effective and reliable full-spectrum light sources, capable of providing a variety of different lighting effects in many applications. Some devices embodying these sources represent the luminous module comprising one or more LED, which is capable of forming different colors, such as red, green, and blue, is also the processor to independently control the output of the LED to the formation of various colors and light effects color changing, for example, as discussed in detail in U.S. patent No. 6016038 and No. 6211626.

Lighting devices of all types are estimated duration of service life and sooner or later fail. Sometimes the failure is sudden (for example, incandescent lamps) or gradual (e.g., fluorescent lamps or light sources based on LED). Defective lighting devices often create problems for many reasons. The lack of sufficient lighting can create a security risk, make unsightly illuminated area or distort the view of the exhibited goods that might scare off potential buyers.

Defective lighting device requires appropriate remedial action, that is, it must be replaced or restored. But it often happens that the emergency lighting device is not always available or inconvenient to immediately replace or repair. This can lead to lack of lighting within an unacceptably large period of time. This scenario is more likely for lighting systems based on LED, as users will not be able to maintain a stock of such devices due to their high cost and the duration of life. This problem can be solved if to provide a warning signal, the decree is living, that'll require remedial action.

Malfunction in the operation of the lighting devices include, but are not limited to: an excessively high temperature, low luminous efficiency, high current or voltage excitation, low fan speed, a large current for driving the fan, or too large a temperature change or the rate of change of temperature. Other faults include faults of sensors and/or hardware bugs and errors such as "divide by zero" in the software and hardware or other problems, well known to specialists in this field of technology.

In many cases, the lighting device becomes defective due to improper functioning or failure of one or more of its component modules. In such a scenario, appropriate remedial action is to replace or repair a specific failed component module (s), and not in replacement of the entire lighting device. In some known lighting systems tools are used for indication of imminent failure. However, since these systems are typically configured only for indicating failure of all of the lighting device, they are not well suited to determine the correct vos is canonicalname activities without additional Troubleshooting.

For example, the lighting device COLORBLAST POWERCORE, supplied by Philips Color Kinetics (Burlington, MA), configured to emit a dim red light in case of overheating. However, there is no indication concerning the causes of overheating, whether internal malfunction, improper installation, end-of-life or high ambient temperature. Thus, alternatives remedial action due to the replacement of the entire lighting device or the attempt to determine the cause of overheating through active Troubleshooting in the lighting device.

As another example, lighting devices, especially those that are mounted in ceilings, typically dissipate the heat by heat conduction to the environment. Often the ceilings are insulated and, therefore, prevent heat loss. Too high temperatures can reduce the service life of the light sources, and to improve heat dissipation in the lighting device, as a rule, set the fan or forced cooling system of another type. However, the service life of the fan can be less than the service life of the light sources. Performance of the fan can deteriorate due to dust, and instead of replacing it may require only the removal of dust and cleaning, or else those who practical service. The same lighting devices are very different to become clogged with dust, depending on the environment in which they are installed. If a warning signal indicates only the inevitable failure of the entire lighting device that most likely means that the lighting device with its functional components is not necessary to replace completely, considering, for example, that a complete replacement may be more expensive than diagnostic testing performed by the technical staff.

Thus, in the art there is a need for systems and methods of providing warning signals for lighting devices that will visually indicate to the user the specific nature of the fault, which will determine the appropriate remedial action. It is also desirable to transmit or display these warning signals to the user an economical and efficient manner.

It should be understood that used here for the disclosure of the present invention, the term "LED" includes any electroluminescent diode or other type of system based on the injection/transfer of charge carriers, which are able to emit radiation in response to an electrical signal. Thus, the term LED includes, but are not limited to: different patterns based on semiconductors that emit light in response to electric current; a light-emitting polymers, organic light emitting diodes (OLED); electroluminescent strips, etc., In particular, the term LED refers to light emitting diodes of all types (including semiconductor and organic light emitting diodes) that may be configured to generate radiation in one or more of the following spectra: infrared, ultraviolet and/or different parts of the visible spectrum (in the General case, including the range of wavelengths from about 400 nanometers to about 700 nanometers). Some examples of LEDs include, but not limited to, various types of infrared LED, UV LED, red LED, blue LED, green LED, yellow LED, amber LED, orange LED and white LED (discussed in detail below). It should also be borne in mind that the LEDs can be configured and/or operated to generate radiation in different frequency bands (for example, full width at half-maximum or FWHM) for the spectrum (for example, narrow band, wide band) and many different dominant wavelengths within this total luminous classification.

For example, one embodiment of the LED configured to generate essentially white light (for example, white LED), can include some crystals that respectively emit different electroluminescent spectra, which are mixed, forming essentially white light. In another embodiment, the implementation of LED white light may contain a phosphorus-containing material, which converts the electroluminescent radiation having a first spectrum, in the other, the second range. In one example of such an implementation electroluminescent radiation with relatively short on the different waves and a narrow range of "pumps" phosphorus-containing material, which, in turn, emits light with a longer wavelength, having a wider range.

Also it should be understood that the term LED does not impose restrictions on the type of physical or electrical performance LED. For example, as discussed above, the term LED may refer to one light-emitting device with multiple crystals, which are configured to emit different spectra (which, for example, may or may not have individual control). Also, the term LED may be associated with phosphorus, which is regarded as an integral part of the LED (for example, some types of white LED). In General, the term LED may refer to the packaged LED, loose LED, LED surface mount, LED open-frame chip LED with T-shaped mounting, LED in a radial design, LED power supplies, LED, containing the shell of a certain type and/or optical element (e.g., diffusion lens), and so on

It should be understood that the term "light source" refers to any one or more of various sources of radiation, including but not limited to: sources based on LED (including one or more LED defined above), incandescent sources (e.g., incandescent lamps, halogen lamps), fluorescent sources, phosphorescent sources, gas discharge sources high intens is Vesti (for example, sodium, mercury and metal halide lamps), lasers, other types of electroluminescent sources, bioluminescent sources (e.g. sources of artificial flames), candle-like luminescent sources (e.g., gas lanterns with glowing nets, sources of radiation from a carbon arc), photoluminescent sources (for example, gas discharge sources), cathode luminescent sources using electronic satiation, galvanoplasty sources, crystallochemistry sources, fluorescent sources used when writing a screen; thermoluminescent sources; triboluminescent sources; sonoluminescent sources; radio-luminescent sources, and luminescent polymers.

Also, this range may have a relatively narrow bandwidth (e.g., FWHM), with only a few frequency components or wavelengths) or relatively Shiro is th band (several frequency components or bands of wavelengths, having different relative levels). It should also be understood that this range may be a result of mixing two or more other spectrums (e.g., mixed radiation emitted from the multiple light sources).

For purposes of this description, the term "color" is used interchangeably with the term "spectrum". However, the term "color" is usually used to refer mainly to the radiation perceived by the observer (although it is not intended that such use limits the scope of this term).

Also it should be understood that the term "color" may be used in connection with both white and not white light.

The term "color temperature" is typically used here in connection with white light, although it is not intended that this use limits the scope of this term.

The term "controller" is generally used here to describe the various devices associated with the actuation of one or more light sources. The controller can be implemented in many different ways (for example, by using special hardware to perform under discussion here of the various functions. One example of the controller is a processor that uses one or more microprocessors that can be programmed using software (e.g., microcode) to perform various functions discussed here.

In the General case, each of the multiple devices connected to the network can have access to the data available on the media or in the communication environment; however, this device can be "addressed" in the sense that it is configured to selectively exchange data (for example, data taken from elsewhere and/or data transmitted anywhere) - based network, for example, one or more specific identifiers (for example, "address") assigned to the device.

Used herein, the term "network" refers to any connection of two or more devices (including controllers or processors) which facilitates the transport of information (for example, for device management, data storage, data exchange, and so on) between any two or more devices and/or between multiple devices connected to the network. It should be borne in mind that different implementations of networks suitable for connections between sets of devices may include any of a variety of different network topologies and use any of a variety of different communication protocols. In addition, in different networks according to the present invention is any connection between the two devices can provide a dedicated connection between two systems, or, alternatively, to represent unselected connection. In addition, for transfer of the information intended for the two devices, such unselected connection can carry information, not necessarily designed for any of these two devices (for example, open a network connection). In addition, it should be clearly understood that various discussed here, the network device may use one or more communication lines (wireless, wired/cable and/or fiber optic) to facilitate the transport of information over the network.

Known lighting devices often provide early warning signals that indicate imminent failure; however, they do not indicate a specific abnormality in the operation of the lighting device. Therefore, the user must either replace all of the lighting device, which is potentially associated with a significant amount, or addition to use of the technologies fault localization, requiring considerable time to identify specific anomalies.

In this regard, applicants have discovered and appreciated the need to provide a method and system that will provide the necessary warning signal indicating a specific abnormal performance parameter or a known combination of a specific abnormal operating parameters of the lighting device. Then the presence of a warning signal determines that there is a problem with the lighting device. In addition, applicants have discovered and appreciated the usefulness of such a warning signal to the user via a visual indicator, for example, the lighting effect generated by the lighting device, and not a separate indicator.

In light of the above is shown the different options and the implementation of the invention relate to a system coded alerts for lighting devices. The system is coded alert includes a detection module to receive one or more operating parameters of the lighting device and the module generating signal for generating a warning signal, which may indicate a particular performance parameter, defined as abnormal, or a known combination of a specific operating parameters that are identified as abnormal.

Information relating to the detection of various operating parameters of the lighting device 100, the receiving module 120 detection and necessary warning signal 131 is generated by the module 130 to generate a signal, if it is determined that one or more operating parameters are abnormal operating parameters.

In some embodiments, the system is coded alerts configured for processing in real time by using, for example, hardware circuits for the detection module and the module generate the signal. In embodiments of the invention, the system coded warnings uses the configuration-based memory that can store information related to the detected operating parameters.

The temperature sensors can be implemented using a thermistor, thermocouple, measure the forward voltage of the light source, integrated circuits for temperature measurement, or by using any other device or method that is sensitive to temperature changes, known to specialists in this field of technology.

In some embodiments, the detection module includes sensors for measuring each operating parameter of the lighting device should be detected. In one embodiment, the one or more operating parameters of the lighting device are detected by the sensors, which is a component of the lighting device. For example, the module on which Eugenia may be functionally associated with the lighting device, so that it can extract data or signals recorded by the sensors of the lighting device.

In some embodiments, one or more operating parameters may be common to several lighting devices and, therefore, to find common sensors. For example, one sensor can be used to determine the ambient temperature in these configurations, lighting devices, where it is logical to assume that the ambient temperature is constant for the entire set of lighting devices. This common sensor may be part of another system. For example, a sensor for measuring the ambient temperature may be part of a thermostatic system of the building.

Information related to operating parameters detected by the sensors, which are external to the system are coded warnings and/or lighting device, can be transmitted to the detection module, the module generating a signal and/or the memory system is encoded alert; and/or controller and/or memory of the lighting device. External sensors can have a communication link with the system coded warnings and/or lighting device using one or more wired communication lines or one or more wireless communication lines (Bluetooth, iFi) or other communication lines, well-known specialists in this field of technology.

In some embodiments, at least one of the operating parameters is detected, for example, when on the lighting device. In addition, one or more operating parameters can be monitored on a continuous basis or on a periodic basis.

In some embodiments, the determination of the operating parameters occurs when turning on or turning off of the lighting device. Detecting operating parameters when turning on or off the lighting device also provides information regarding the operation of the lighting device in transitional regimes. Specialists in the art should be obvious that the detection of operating parameters in transient conditions can provide useful information regarding the potential failure of the lighting device, which can not be obtained by detecting the operating parameters in steady-state conditions (for example, information relating to power surges that may appear when turning on the lighting device).

In some variations, the detection module may be configured to receive one or more derivatives of the operating parameters of one or more detected operating parameters. For example, the temperature of the p-n junction LED, is used as the IP is the light source, can be obtained from the value of the forward voltage of the LED.

In some embodiments, the derived performance parameters can be obtained by processing in real time, for example, using specialized circuits. Specialized schema can represent, for example, the integrator circuit, a comparator circuit, or so on; and they can receive signals related to one or more detected operating parameters. In one embodiment, the integrator circuit provides the derived performance parameter based on the integration of one working parameter over time. In another embodiment, the comparator circuit is used to provide a derived work of a parameter based on a comparison of the two signals, for example, the measured temperature from the temperature sensor functionally associated with the lighting device, and the measured ambient temperature from the total temperature sensor.

In some embodiments, to calculate the derivatives of the operating parameters on the basis of the detected operating parameters using one or more computing elements. For example, the computing elements can be used to provide a derived work of the parameter derived from one or more operating parameters using empirical formulas.

In some embodiments, the module found what I includes a feedback circuit. In some embodiments of the invention, the feedback circuit may be configured to lock one or more operating parameters of the lighting device that allows you to map these operating parameters with one or more previously recorded operating parameters. For example, this mapping of one or more current and past operating parameters may provide the key to determining deviates whether the operation mode specific components of the lighting module from the norm. For example, it is known that over time, the luminous flux emerging from the LED, weakened, and then the feedback circuit may be configured to estimate how did weakening of the light output from the LED to the outside of the normal range.

The module generating signal

Module generating a signal receives information related to the detected and/or derived operating parameters of the lighting device of the detection module and/or controller of the lighting device, and/or from other sources (for example, of the total sensors). In some embodiments, the module generating a signal can be configured to receive one or more derivatives of the operating parameters of one or more detected operating parameters.

Module generating a signal creates the necessary warning signal if the determined one or more operating parameters are abnormal, where a warning signal indicates abnormal performance parameter or a known combination of abnormal operating parameters. Abnormal working parameter can be, for example, too high temperature, low light output, high current excitation, a large excitation voltage or etc.

Necessary warning signal generated by the module generating the signal, choose from a variety of warning signals. Each of the specified set of warning signals indicates the specific abnormal performance parameter or a known combination of a specific abnormal operating parameters. Thus, the necessary warning signal generated by the module generation of the signal depends on the type of detected anomalies and allows the user to select an appropriate remedial action.

The definition of anomalies detected and/or derivatives operating parameters can be ensured in different ways. In some embodiments, determine that the working parameter is abnormal, when he is outside a predetermined range. This pre-defined range of normal values can be programmed for at least one or more operating parameters.

In some variants of the Ah define the work parameter is abnormal only when it goes beyond a predetermined range a predetermined number of times. This predetermined number of the outputs is outside of a predetermined range may be different for each operating parameter and/or a known combination of specific operating parameters. Exemplary encoding scheme shown in the table below for the scenario in which the system coded warnings determines the excitation current source (s) of light in the lighting device and the excitation current of the fan is used for forced cooling. As defined for this example, the generation of a signal does not occur at low values of current excitation source (s) light and fan; however, when it is determined that either or both of the excitation current are abnormal (e.g., high), suitable warning signal is selected from a variety of warning signals (S0, S1, S2) according to the coding scheme (see table).

The excitation light source; an excitation current fanThe generated warning signal
Low; lowNo Dan is s
High; lowS0
Low; highS1
High; highS2

The user can choose the appropriate remedial action based on the generated warning signal. For example, the user may replace the source (s) of light that is generated when the signal S0, replace the fan, when generating the signal S1, and replace all of the lighting device, when generating the signal S2.

Specialists in the art should understand that the coding scheme can be more complicated for more complex lighting applications that require the detection of a larger number of operating parameters. The number of warning signals used by the coding scheme depends on the number of specific abnormal operating parameters and the number of known combinations of specific abnormal operating parameters that would like to have the user for display provided by the system coded warnings. Thus, the encoding scheme is one-to-one mapping between the generated warning signal and specific abnormal working parameter and the/and is known and a combination of a specific abnormal operating parameters.

The encoding scheme can be implemented by modules generate the signal using a lookup table stored in the associated memory module, or implemented in hardware. The encoding scheme, for example, may be programmable, allowing the user to modify the search table.

In some embodiments, the alarms can be programmed with the possibility of extension depending on the time elapsed since the first alarm. For example, the sequence of the five blinking may indicate the presence of high excitation current for source (s) of light and can be expanded to a sequence of ten blinks, if remedial action has not been performed within a predetermined period of time.

Each of the many warning signals used in the encoding scheme may be transferred to the user in different ways, for example, by visual, audio or electronic indicators. Each of the warning signals can also be transmitted in the form of a combination of one or more component signals of different types. For example, a warning signal S2 from the coding scheme on a table can have both visual and audio component, while a warning signal S1 may be the only visual component.

In some embodiments, the individual components of the warning signal can be connected to each other. In some embodiments, there is a one-to-one mapping between the electronic component and the audio component of the warning signal. For example, the electronic component can be used to create audio components that provides one-to-one mapping between them. In one embodiment, the first warning signal uses five blinks as visual components and five short beeps sound components; while in the second warning signal is used ten blinks as visual components and ten short beeps as audio components.

In some embodiments, each of the many warning signals may contain a unique visual component, and to use total audio component (e.g., a loud beep). For example, the shared audio component alerts the user to the presence of anomalies in the operation of the lighting device, while a unique visual component will point the interested user is detected specific abnormal performance parameter or a known combination of abnormal operating parameters. Then, the mapping between visually the component and the audio component will be a type of "many - one."

In some embodiments, each of the multiple warning signal is e, and a warning signal is used to generate a visual warning indicator, for example, light effect, and/or audible warning indicator. The visual warning indicator can be obtained, for example, through the use of appropriate electronic warning signal for the excitation of one or more light sources in a particular way to create, for example, one or more flashes; one or more instant reduction of intensity; temporary color change; the number of color changes; variations in the light output using different time scales, time durations, intensities and/or colors; and one or more combinations thereof.

Source (s) of light used to create the visual warning indicator may be outside of the lighting device (for example, a separate indicator lamp) or preferably may be at least one of the light sources of the lighting device. In some embodiments (see Fig. 4A-4B) requires a warning signal is generated module 630, 730 generating a signal based on the information received from module 620, 720 is present is ugenia and/or memory 640, 740. Necessary warning signal is transmitted via the communication line (well known to experts in the art) to the controller 605, 705 lighting device for initiating at least one of the sources 602, 702 light to create a visual warning indicator, for example, a particular lighting effect, appropriate and necessary warning signal. Thus, the lighting device uses its own source (s) of light to transmit a warning signal to the user. When necessary warning signal indicates the detected specific abnormal condition, the resulting visual warning indicator also identifies the detected specific abnormal condition. For example, the number of red flashes may indicate that the source (s) of light almost worn out, and therefore require replacement, while the signal in the idea of blue flashes may indicate that the cooling system needs attention. In the embodiments of Fig.4A-4B lighting device and system coded alerts share a common source 650, 750 power supply and a common switching element 651, 751.

In some embodiments, the necessary electronic warning signal can also use Atisa to create a sound warning indicator.

In embodiments of the invention will require a warning signal can be transmitted from the module generate a signal to the Central control device, which is used for current control for multiple lighting devices. With the necessary warning signal may be associated with an identification tag that allows you to easily identify the corresponding lighting device to the Central control device. Specialists in the art should be obvious that the delay between detection of operating parameters and generating the necessary warning signal depends on the technical solution of a system of coded warnings. The technical solution of a system of coded alerts on memory-based (as opposed to processing in real time) allows programming of the above-mentioned delay.

One module generating a signal can be shared by many lighting devices. In one embodiment, the set of lighting devices, each of which is functionally connected with a specialized detection module uses a common module to generate a signal. General module generating a signal receives information relating to operational parameters from each of the specialized fashion is lei detection. In one embodiment, the set of lighting devices share a common module generating a signal in the time division mode.

In one embodiment, the detection module and the module generating a signal can be combined into a single module. In one embodiment, the detection module and/or module generating a signal can be combined with the controller of the lighting device. The detection modules and/or the generation of a signal can be used by the microprocessor. Because of the lighting devices based on solid-state light sources, typically, controllers are used, it may facilitate the modification of the electronic circuits or hardware controller to enable additional functionality of the system coded warnings.

In some embodiments, one system coded alerts shared across multiple lighting devices in a time division mode. For example, the necessary warning signal can be generated actually in the moment of switching on or off of the lighting device. In one embodiment, the necessary warning signal is generated when the second or subsequent switching on or off of the lighting device. Coordination of alarm activation or disabling the educational device can increase the probability of the user will be informed about the inevitable failure of the lighting device (for example, due to the fact that he/she is probably nearby). Suitable means may be included in a system of coded warnings and/or lighting device to provide sufficient power for the alarm when off.

Functionality to determine whether one or more operating parameters of abnormal operating parameters, can be implemented by the detection module and/or module generating a signal.

Memory

Please refer to Fig.3A-b, where the system is coded alert includes a memory 440, 540, defined above, for storing information relating to detected and/or derivatives of operating parameters. System of coded messages is functionally connected with the lighting device containing the source 402, 502 of the light and the controller 405, 505, and may share a common source 450, 550 power supply using a switching element 451, 551. When generating the necessary warning signal 431, 531 also takes into account the contents of the electronic memory 440, 540. The contents of the electronic memory 440, 540 may be available module 430, 530 generate a signal or indirectly through module 420 detection (Fig.3A), l is Bo directly (Fig.3B) without using module 420 detection. In one embodiment, the detection module determines whether a work setting is abnormal, and the memory memorizes the fact that the working parameter is defined as abnormal. In some embodiments, the memory memorizes all detected operating parameters to further define the anomaly-detection module and/or module generating a signal. The system is coded alerts based memory may be configured to introduce delay between generating the necessary alarm and detection parameters.

In Fig.5A-5C show various block diagrams of the operation of the system coded alerts with functionally related lighting device. In one exemplary process shown in Fig.5A, is the inclusion of the lighting unit 31 and the definition of 32 working condition. If the status is abnormal 33, it generates a corresponding warning signal 34 indicating the abnormal state, after which the lighting device is on 35, as it should be according to the user action, which it was included. If the condition is not abnormal 33, the warning signals are not generated and the light, as expected, remains on 35.

In one configuration, shown in Fig.5B, the abnormal status is of memorized in the memory. You are enabling 41 of the lighting device, and the detection module 42 receives information relating to operating States of the source (s) of light and/or controller, while the lighting device is on. If the detected abnormal condition 43, it is memorized 45 in memory, and then the light, as required, remains on 46. Otherwise, the detection module continues to monitor operating States either continuously or intermittently, after a delay of 44.

In Fig.5C shows a block diagram, where the detection module reads the abnormal state of the memory and indicates this by disabling. The lighting device is switched on 51 and remains activated for the appropriate period of 52. Disabling 53 detection module reads the contents of the memory and, if the abnormal state 55, 56 generates a signal that indicates a specific abnormal condition to full off 57 light. If the abnormal state 55 is absent, the alarm is not running. Specialists in the art should be obvious that to resolve the alarm when off, you must have an adequate supply of energy in the different modules, and they are well known appropriate technical solutions.

In some embodiments, the lighting device is TWT can be configured its work force is blocked by the protection circuit. For example, if the detected hazardous condition, then the protection circuit will shut down the lighting device, however, if the potentially dangerous condition, the system coded alerts can generate a signal indicating a dangerous condition before complete disconnection of the lighting device, or can be memorized in the memory an indication about the dangerous condition. When you turn the system coded alerts can generate a signal representing a dangerous condition, after which the lighting device is turned off by the protection circuit. This dangerous condition can be, for example, an unusually high temperature.

Due to aging, as well as when using relatively simple technical solutions of the lighting device without a feedback circuit, the light output may be reduced gradually that it is difficult to notice. A gradual decrease in light output is also possible in lighting devices with feedback when the controller operates at the limit of the approach end-of-life source (s) of light. In one exemplary system configuration coded alert detection module configured to obtain information relating to the light source (s) of light. When the light intensity is below a predetermined first threshold, module generating a signal generates a first warning signal, which is used by the controller to generate the first visual warning indicator: for example, a one-time reduction in light output after power-on. This visual warning indicator indicates to the user that the lighting device is soon to be replaced. As possible, but optional option, as soon as the light intensity falls below a predetermined second threshold, can generate another warning signal, leading to the creation of a second visual warning indicator: for example, a momentary power outage after power-on.

In another exemplary system configuration coded alert detection module determines the operating hours of the lighting device, the excitation current and the operating temperature of the source (s) of light. If the temperature is high and the number of working hours is low, it generates the first warning signal indicating improper installation, for example, the light source is re-installed in a poorly ventilated area. If the temperature is high, the number of working hours is not so little, and the excitation current in the norm, it generates a second warning signal indicating that the cleaning required light is on device for example, by removing the dust accumulated in the fan heatsinks. If the temperature, the excitation current and the number of hours high, it generates a third warning signal, indicating that the source (s) of light and/or all of the lighting device soon to be replaced.

Example 1

In Fig.6 shows a block diagram of an exemplary lighting device functionally associated with the system coded alerts according to the invention. The lighting device includes a matrix 20, 30, 40, each of which has multiple light sources based on LED, which have thermal contact with one or more heat sinks, or with the systems of heat (not shown). In one embodiment, the springs 22 red light, green light sources 32 and blue light sources 42 in the plates 20, 30, 40 can be mounted on separate heat sinks. The combination of colored light generated by each of the springs 22 red light, green light sources 32 and blue light sources 42 may generate light of a particular color, for example white light. In one embodiment, the lighting device includes a mixing optics (not shown) for spatial homogenization of the output light generated by mixing light from the light sources 22 of the red light sources 32 green Sveti sources 42 blue light.

The matrix 20, 30, 40 connected pathogens 28, 38, 48 current, respectively, which are configured to supply current to the red light sources 22, the springs 32 green light and blue light sources 42 in the plates 20, 30, 40. Pathogens 28, 38, 48 current control output light flows sources 22 red light, green light sources 32 and blue light sources 42 by regulating the current passing through the red light sources 22, the springs 32 green light and blue light sources 42. Pathogens 28, 38, 48 current can be configured to regulate the flow of current in the matrix 20, 30, 40 independent, interdependent and/or a dependent, in order to control the chromaticity of the combined light, as described below.

In one embodiment, the agents 28, 38 and 48 DC can use the technology of pulse width modulation (PWM) to control the output light flows sources 22 red light, green light sources 32 and blue light sources 42. Since the average output current in the sources of the red light sources, green light or blue light is emitted is proportional to the fill factor of the control signal PWM, you can reduce the light output generated by the sources of the red light sources, green light or blue light sources, by adjusting the fill factor on the I each matrix 20, 30 and 40, respectively. The frequency of the control signal PWM to the sources of red light sources, green light or blue light sources can be chosen in such a way that the human eye perceived light output as a constant and not as a sequence of light pulses, for example, to select a frequency greater than about 60 Hz. Alternatively, the management agents 28, 38, 48 current is performed using pulse-code modulation (PCM) or other digital format known in the art.

To the output of pathogens 28, 38, 48 current connected sensors 29, 39, 49 AC, which measure instantaneous forward current, supplied to the matrix 20, 30, 40 light sources. Current sensors, as an option, but not necessarily, are: fixed resistor, variable resistor, the inductor, the current sensor on the Hall effect or other item that has a known voltage-current characteristic and can provide a measurement of the current flowing through the load, for example a matrix of one or more light sources based on the measured voltage signal. In an alternative embodiment, can be detected peak direct currents for each matrix 20, 30 or 40 in relation to a predetermined value in order to avoid measurements of instantaneous forward current, supplied to the matrix 20, 30 and 40 in a given time.

To pathogens 28, 38, 48 current is connected to the controller 50. The controller 50 is configured to average forward current by adjusting the duty cycle of the cycle of pathogens current, which provides control of the output luminous flux. The controller may also be connected to the sensors 29, 39, 49 current and can be configured for monitoring instantaneous forward current, supplied to the matrix 20, 30, 40 pathogens current.

In one embodiment, to the output of pathogens 28, 38, 48 current connected sensors 27, 37, 47 excitation, which measure instantaneous forward voltage matrix 20, 30, 40 light sources. The controller 50 is connected to the voltage sensors and configured for monitoring instantaneous forward voltage matrix of light sources. Since the temperature dependence of p-n junction of the source of light from the excitation current is substantially linear, the temperature of the p-n junction of the light source can be determined, for example, by measuring the forward voltage of the light source.

In addition, the lighting device includes systems 60, 70, 80 optical sensors, which can be functionally connected with the configuration for proportional-integral-differential (PID) control feedback with PID controller 90, which may be built in to control the EP 50 in hardware design. As an alternative, the PID controller can be a separate component that is functionally connected to the controller 50.

Each system 60, 70, 80 optical sensor generates a signal representing the average spectral irradiance of the matrix 20, 30, 40. Each optical sensor includes, for example, optical sensors 62, 72, 82, which may represent, for example, a photodiode that is sensitive to spectral flux emitted from the matrix. In one embodiment, each optical sensor may be configured in such a way that he perceived a light in a narrow wavelength range. To measure the contribution of the sources 22 red light, green light sources 32 and blue light sources 42 can be preferably used red, green and blue optical sensors, respectively. As an option, but not necessarily, each optical sensor may be provided with a filter 64, 74, 84, could limit the wavelengths of light incident on the respective optical sensor. For example, when you want a specific optical sensor recorded only a specific wavelength range, which is a subrange of the wavelength range to which this sensitive optical sensor, the optical filter associated with this optical sensor, may provide limited wavelength pad the irradiation light within the boundaries of the required range. Optical filters can be a thin-film interference filters, colored plastic, painted glass, or so on, it is Clear that you can use several types of optical sensors, such as photodiodes, photointerrupter integrated circuits (IC) photosensor, unexcited LED, etc.

For temperature measurement matrix can include one or more sensors 26, 36, 46 temperature, in thermal contact with one or more heat sinks and connected to the controller 50. The temperature of the matrices can be correlated with the temperature of the p-n junction of the red light sources 22, the springs 32 green light and blue light sources 42.

In one embodiment, the installation of red light sources 22, the springs 32 green light and blue light sources 42 may be implemented on separate heat sinks or other systems of heat with separate temperature sensors in thermal contact with them. It is clear that the installation of red light sources, green light sources and blue light sources can also be performed on the same heat sink, and then to determine the temperature of the p-n junction of the red light sources, green light sources and blue light sources will need at least one temperature sensor. In another embodiment, the sensors 26, 36, 46 temperature, R is smashout next to each matrix 20, 30 or 40 light sources to obtain a more accurate temperature values p-n junction of the red light sources, green light sources and blue light sources, respectively. Note that the red light sources, green light sources and blue light sources is likely to operate in pulsed mode with a frequency much higher than thermal time constant of one or more heat sinks, and therefore, the temperature sensor is likely to show the average heat load.

In one embodiment, the sensors 26, 36, 46 temperature can be achieved by using a thermistor, thermocouple, measure the forward voltage of the light source, integrated circuits for temperature measurement or any other device or method that is sensitive to temperature changes, known to specialists in this field of technology.

The controller 50 is functionally connected to a system of coded alerts according to the invention. The system is coded alerts includes module 820 detection, configured to obtain from the controller the information relating to one or more operating parameters of the lighting device. Module 820 detection receives from the controller the information relating to the measurements made by the sensors 29, 39, 49 current sensors 27, 37, 47 voltage, dates, what IKI 26, 36, 46 temperature, and systems 60, 70, 80 optical sensors. The detection module, as an option, but not necessarily, may also receive information regarding one or more operating parameters of the lighting device from additional sensors (not shown), which may be external or internal to the lighting device. In addition, the detection module also receives from the controller the information related to the error type "division by zero" in the software-hardware, software errors, hardware or other errors, which are well known to specialists in this field of technology.

For a system of coded alerts configuration is based on memory, which allows you to record information related to one or more detected operating parameters of the lighting device in the electronic memory 840, which is functionally connected with the module 820 detection. Thus, recorded in the electronic memory information includes information relating to measurements made by the sensors 29, 39, 49 current sensors 27, 37, 47 voltage sensors 26, 36, 46 temperature, and systems 60, 70, 80 optical sensors and the controller.

For recorded information has access, at least partially, the module 830 generate a signal which via the module 820 detection to generate the necessary warning signal, selected from a variety of warning signals. Each warning signal from a variety of warning signals indicates the specific abnormal performance parameter or a known combination of a specific abnormal operating parameters. Configuration-based memory implies that generating the necessary warning signal module signal generating and receiving module detection information related to the detected operating parameters, can occur at different points in time. In one embodiment, the information relating to the detected operating parameters, appears continuously as soon turn on the lighting device, while necessary warning signal is generated only when turning on the lighting device.

Necessary warning signal generated by module 830 generate a signal that is sent to the controller 50 and is used to define agents 28, 38, 48 power and control on the basis of their light sources of red light sources, green light and blue light sources, respectively, to create a visual warning indicator. The thus created a visual warning indicator indicates the specific abnormal performance parameter or a known combination to skretny abnormal operating parameters.

Necessary warning signal generated by the module 830 generate a signal, it is also possible, but not necessary, to use (as shown by dashed lines) to separate excitation light source (for example, indicator lamp 851) with the aim of creating a visual warning indicator; and/or be used to initiate a sound generator 853 to create sound a warning indicator.

Example 2

Please refer to Fig.7, which shows an exemplary lighting device 1 with a removable fan module. The lighting device 1 is intended for mounting in the recess of the ceiling (shown in dotted outline 2) by fixing the 3 screws. The fan 4 is placed with the possibility of its removal on the circuit Board 8, is configured as a controller for a lighting device in the upper part of the lighting device. When activated, the fan 4 rotates, directing the air along the path 6 between the side wall of the lighting device 1 and the recess 2. The air leaves the upper part of the lighting device along the path 7 between the opposite side wall of the lighting device 1 and the recess 2. Reflective walls 5 can provide the supply air flow essentially from one side of the lighting device 1 to another, which does not circulate in the upper volume of the recess 2. Please refer to Fig.8A (cross-section when viewed from above), where the flow is 6, 7 air passes through the heat sink, mounted on the printed circuit Board 8, and remove the dissipated heat.

In Fig.8B shows a section of the lighting device 1 when viewed from the side. The fan 4 is mechanically fixed in place in the holders 9 and/or 15. Any of these holders may also provide electrical connection for the fan. Base 14 may also be a circuit Board and can be connected to the circuit Board 8 wires 19. On the boards 14 and 8 can be mounted additional components 11, 12. Sources 13 light mounted on the bottom side of the PCB 8.

In Fig.9A shows a half-section of the lighting device 1 at an angle of 90° relative to each other. To optimize the flow of air gap between the reflective walls 5 and the recess 2 should be much less of a gap between the periphery of the lighting device and the side wall 17. In particular, the area 20 of the gap 16, multiplied by the length (x+y) must be much smaller area 18A or 18B in Fig.9B, is found by multiplying the gap 17 on the length of πr. The shape of the reflective walls 5 should actually fit the shape of the recess.

The fan can be a fan with variable speed. The fan can have a high speed, to the which increases the air flow several times, to remove some of the dust from time to time, or when you have to do this by reducing the cooling efficiency. The fan occasionally may operate in reverse flow also helps to remove the dust.

The fan can be replaced when it is clogged with dust, or when I had collected so much dust that it cannot rotate when voltage is applied, or when the cooling system as a whole has become ineffective because of the dust. The user can remove the lighting device from the holder and remove the fan for cleaning or replacement. Can also be removed dust around the heat sink and cleaned up other ways for air. However, even the interested user is not easy to determine whether a cause of lowering the light output of the lighting device that the LEDs are at the limit of their service life, or that built-in temperature control initiated the excitation level of the LEDs below the ideal conditions due to a decrease in the efficiency of the cooling system due to the dust.

Thus, the lighting device is functionally connected with a system of coded alerts, where the detection module determines the intensity of the cooling of the lighting device and the excitation current for the fan module. The intensity of cooling the Oia can be measured by monitoring temperature, for example, LEDs or heat sink during a certain time period after turning on of the lighting device. Ambient temperature can also be taken into account, for example, by means of its relative measurements.

If the rate of cooling is too low, for example, due to accumulated dust, the module generating a signal generates a first warning signal. This condition may be recorded in the electronic memory, and an alarm is provided or when turning off and/or for subsequent inclusion.

Although there has been described and illustrated several patentable options, specialists in the art will easily be able to offer a variety of other means and/or structures for performing the described functions and/or the teachings described results, and/or one or more of the benefits described here, and the premise that each of these versions and/or modifications are beyond the scope described here variants of the invention. In a more General case, specialists in the art should be obvious that all of the settings described here, the dimensions, materials and configurations are given only as examples, and that the actual parameters, dimensions, materials and/or configurations will depend upon the particular application or applications that will be used proposed here patentable principles. Specialists in the art will know or can estimate using only routine experimentation, many equivalents to the specific options described here. Thus, it should be clear that the above options are presented only as examples and that within the scope and appended claims and its equivalents can be practically implemented variants of the invention other than the specific described and claimed here options. Variants of the present invention described herein relate to each individual feature, system, article, material, kit and/or method. In addition, the scope of the present invention includes any combination of two or more of these signs, with the stem, products, materials, kits and/or methods, if such features, systems, articles, materials, kits and/or methods are not mutually exclusive.

It should be understood that all described and used here definitions apply to dictionary definitions, definitions in the documents incorporated here by reference, and/or typical values defined here in terms.

In this description and the claims the singular does not exclude the plural.

Used in this description and the claims, the phrase "and/or" should be understood as "either or both" of the combined elements, i.e. elements that are conjunctive in some cases and disjunctive present in other cases. Many of the items listed using the phrase "and/or" should be treated similarly, i.e., one or more of these elements. Can, but not necessarily, be present other elements other than the elements specifically identified as the expression "and/or", regardless of whether they are associated with the specified specifically identified items. Thus, as a non-limiting example, the link "and/or" when used in connection with an extensible language, the term "containing" in one embodiment, can only refer to A (possibly what about including elements, other than B); in another embodiment, only In a (possibly including elements other than A); in another embodiment, to A, and to (possibly including other elements); etc

Used in this description and the claims the word "or" should be understood as having the same meaning as videopreteen the phrase "and/or". For example, when separating items in a list "or" or "and/or" should be interpreted as inclusive, that is, as the inclusion of at least one, but also including more than one in number or list of elements, and optional additional elements not included in the list. Only terms with clearly specified opposite meaning, such as "only one" or "just one" or when used in the claims "made up of" will refer to the inclusion of exactly one element of a number or list of elements. In the General case used here, the term "or" should be interpreted only as pointing to exclusive alternatives (i.e., "one or the other, but not both"), if they are preceded by terms of exclusivity, such as "any", "one", "only one" or "just one". The phrase "consisting essentially of" when used in the claims has its ordinary meaning as used in the field of patent law.

Used in this op is sanija and the claims, the phrase "at least one" when referring to a list containing one or more elements, should be understood as at least one element selected from any one or more items in the item list, and here it is not necessary to include at least one of any item specifically listed in the list of items, and there is no need to exclude any combination of the items mentioned in the list of items. This definition also allows, but does not necessarily, be present elements other than the elements specifically identified in the above list of items, which include the phrase "at least one", regardless of whether or not to mentioned specifically identified items. Thus, as a non-limiting example, the phrase "at least one of a and b" (or equivalent "at least one of a or b" or equivalent "at least one of a and/or b"), In one embodiment, may include at least one (not necessarily including more than one) And in the absence (and, but not necessarily, including elements other than B); in another embodiment at least one (optionally including more than one) without And (and, but not necessarily including elements other than A); in yet another variant, at least one (not necessarily including Breedlove) and, at least one (optionally including more than one) (and optionally including other elements); etc

It should also be understood that, unless expressly stated otherwise, any stated here, which includes more than one step or steps, the order of these steps or actions in a way not necessarily limited to set out here the order of the aforementioned steps or actions.
