Area of technology

The present invention relates to lighting systems and, in particular, to an illumination system containing a variety of lighting devices, each of which is arranged to transmit an identification code in the emitted light, and the device of choice, made with the possibility to choose at least one of the lighting devices on the basis of his/their identity(ies) code(s). In addition, the corresponding method.

The level of technology

Lighting systems containing many lighting devices that use data from individual lighting devices in the emitted light, are known. In WO2006/079199 discloses a lighting device comprising LEDs, the LEDs are driven, for example, pulse width modulation, PWM, signal which modulated data signal. In addition, the receiving means is used for receiving the data signal by means of light emitted by the LED, through the registration of all (or part) of the illumination provided by the LEDs. Then the data signal is allocated from a registered lighting.

Such methods were previously used in method guidance and control for lighting. Usually portable device is arranged to select an individual light up�individual devices and manage them by specifying one or more lighting devices and identification of the lighting unit by the extracted identification code. The identification code may be contained in the lighting device and transmitted to the device selection by invisible to the eyes of modulation of the light output of a lighting device, for example through pulse width modulation, PWM. Thus, the identification code modulates the average intensity of light output from the lighting device. This allows the device of choice to choose the lighting device on the basis of the extracted identification code sent in his sight.

However, the above-described system, where the data is, for example, in the form of identification codes are emitted and logged in from radiated light, have several disadvantages. When receiving the identification codes from the plurality of lighting devices of the receiver for a number of reasons may not be able to lay out the individual signals, for example due to low intensity of light, blocking of objects in the room, the distortion of the modulation signal, etc.

Summary of the invention

The present invention is to overcome this difficulty and providing an improved lighting system and method for selecting a lighting device in such a lighting system. According to the first aspect of the invention, these and other problems are solved by an illumination system containing a multitude of�vetically devices, each of which is arranged to transmit light emitted by the identification code ID. The illumination system further comprises a control unit, configured to identify at least one lighting device, the initial value of the excitation of which is equal to or less than the minimum predetermined value or equal to or greater than the maximum pre-set value. The control unit is further configured to set the value of the institution of such identified lighting device on the specified values.

The invention is based on the fact that the identification codes are implemented in the emitted light as intensity modulation. In the case of too low or too high excitation signal (corresponding to the intensity of light is very small and close to the maximum, respectively), the available modulation depth becomes an important factor in ensuring a good signal-to-noise ratio when registering identification codes. Thus, the result is a lighting system in which the identified lighting devices, working with an initial value of excitation is too low or too high to ensure reliable and preferably smooth (registration) modulation intensity�STI, and in which the value of the institution of the identified lighting devices is fixed to the preset value. For a given value of the available modulation depth is large enough to achieve good signal-to-noise ratio for the registration codes.

According to the embodiment of the lighting system, the system further comprises a device adapted to select at least one of the lighting devices. The selection is made on the basis of the identification codes.

According to variants of implementation of the lighting system, the device is arranged to send the first initialization command and, optionally, a second initialization command. After receiving the first initialization command, all lights, except for at least one identified lighting device, transmit their identification codes. The step of setting values of excitation identified by the(s) light(s) of the instrument(s) shall be done after the second initialization commands, and after the setup phase, at least one identified lighting device transmits his/her identification(s) code(s).

Thus, the device select registers the first set of readings lighting products that provide�Ecevit strong reliable signal identification code. Then the second command activates the initialization setting of the excitation to improve the quality of the transmission/reception identification code for the identified lighting devices that cannot properly be modulated during its initial installations, the values of excitation. Usually a small number of the identified lighting devices, for example, only a few (m) of the total number of lamps (N), is excited with <10% >90% of the maximum value of the excitation, respectively. Thus, the probability that the user will want to choose one of them small: ~m/N<<1. Consequently, the majority of the time the user will only send one command initialization.

According to the embodiment of the lighting system, the minimum and/or maximum pre-set values are set to the selection phase.

The set value of the excitation (and thus the intensity level of the emitted light) can mostly be installed on a device of choice, or when commissioning of lighting fixtures (setup), or at a later stage. For colored lamps containing more than one color channel (color light sources, for example red, green and blue LEDs), you can select one color channel for supplying excitation �odnogo values. On the one hand, this will lead to a slight shift of the color point of the emitted light, but at the same time, will limit the change in the total intensity of the light fixture.

According to the embodiment of the lighting system, the minimum and/or maximum pre-set values are set at the selection stage.

Dynamic setting minimum or maximum value has the advantage, for example, when the lighting device has a very low value of excitation close to the powered off state of the lighting device. For this the device of choice initially given the opportunity to install low minimum preset value, and when the device does not detect sufficient signal reception device increases the minimum preset value of a lighting device to achieve reliable reception of the emitted light. This results in a minimal increase in the level of full intensity light emitted from the lighting device and, at the same time, ensures a reliable registration. It makes less visible the change of lighting in the room during the transmission of the identification code. A similar procedure can be performed to obtain reliable reception for the lamp near the maximum.

<> According to the embodiment of the lighting system, the set value of the excitation may be a fixed percentage of the minimum or maximum predetermined values, respectively. To minimize any perception of changes in the intensity of light from the lighting device at the stage of choosing the set value of the excitation is preferably set to a value that significantly deviates from the initial value of excitation, therefore, the value of the excitation light unit is operating in the mode of low luminosity increases, for example, up to 10% of the maximum value of excitation for a lighting device, and the value of excitation lighting device operating in a mode close to the maximum, is set equal to, for example, 90% of the maximum value of excitation for a lighting device, respectively, prior to transmission of the identification code.

According to the embodiment of the lighting system, the block selection is made with the possibility to adjust the minimum pre-set value based on the signal-to-noise ratio of the light detected by the device of choice. Thus, the ratio of the excitation signal to noise to measure the light on the device is mainly used in kachestvenii to obtain the minimum of the intensity of the output light (in accordance with the set value of the excitation) identified lighting device.

According to the embodiment of the lighting system after the selection step, the value of the excitation identified lighting device may slowly return to its initial value of excitation (i.e., to return within a specified time interval). The time during which the device select selects the lighting device is relatively small, typically about 200 MS. Due to the fact that the value of the excitation (which corresponds to the intensity of light emitted from the lighting device) identified by the lighting device may slowly return to its initial value, the risk of user perception changes light intensity is reduced.

According to the embodiment of the lighting system, the initial value of the excitation corresponds to an average output light intensity.

In addition, according to the second aspect of the present invention, there is provided a method of selecting a lighting device of the plurality of lighting devices. The method contains the stages at which identify at least one lighting device, the initial value of the excitation of which is equal to or less than the minimum predetermined value or equal to or greater than the maximum predetermined value, passed from each lighting p�of psi identification code in the emitted light, set the value of the intensity of such identified lighting unit by a predetermined intensity value, record identification codes and choose the lighting device based on the registered identification code. The second aspect of the invention may, in General, to have the same characteristics and advantages as the first aspect.

According to the embodiment of the method, the method further comprises a stage on which provide the first initialization command. In response to the first command, the initialization step of transmitting is performed for all lighting fixtures, in addition to at least one identified lighting device. The method further comprises an optional step in which second issue the initialize command. In response to the second initialization command for at least one identified lighting device is performed during installation, and for at least one identified lighting device is carried out during transfer.

According to the embodiment of the method, the method further comprises, after the selection stage, a stage where slowly return the value of the excitation identified lighting device to its initial value (i.e., return over a given time interval�).

These and other aspects, features and advantages of the invention will be explained and illustrated with reference to the following possibilities of implementation. Note that the invention covers all possible combinations of features specified in the claims.

Detailed description

Below will be described in more detail according to embodiments of the present invention with reference to the accompanying drawings showing some embodiments of Fig�plants. However, this invention allows the realization of many other forms and is not subject to limitation of the presented here options of implementation; on the contrary, these implementation options are shown by way of example, for a more complete understanding of the disclosure and bringing the full scope of the invention to specialists in this field of technology. Similar reference position refer to similar elements throughout the description. In the future under the nominal value of the excitation is understood to be the initial value of excitation.

Fig. 1 shows a variant implementation of the lighting system 100 according to the present invention. Many lighting devices 101a-g installed, for example, on the ceiling to illuminate the room. Each lighting device is arranged to transmit an identification code ID in the emitted light. The user selects the lighting device through the device 120 to manage them in a special way. The device 120 selecting able to choose lighting device from the plurality of lighting devices, recording the light emitted from lighting devices, and identifying individual lighting devices on the basis of their ID codes. In addition, each lighting device comprises (or is associated with) block 130 control made with the possibility of ID�to differentiate lighting, having too high or too low value of excitation (corresponding to an average value of light intensity in the mode of luminosity is close to the maximum and in the low luminosity regime, respectively), and to set the value of the institution of the identified lighting units on a given value of excitation.

Fig. 2a-c lighting system that meets the invention, presented in more detail. Illustrative variant implementation of the lighting system 200 contains a variety of lighting devices based on LEDs 101a-d. Each of the lighting devices 101a-d are arranged to transmit in its emitted light of the identification code IDa-d. In this example, lighting devices based on LEDs 101a-d applied by means of pulse width modulation (PWM) in an appropriate electric circuit 112 excitation to set the intensity of the light emitted from the lighting device. In General, the PWM is controlled by two registers, one of which regulates the duty cycle of the pulses, which corresponds to the intensity of light output from the lighting device and the other sets the PWM frequency. Both registers can, in General, be installed using the firmware provided in the block 130 control. Since the PWM frequency exceeds several�to hundreds of Hertz, the human eye is, in essence, reject it. Due to the fact that each lighting device 101a-d is assigned a separate frequency PWM device 120 selecting, equipped with svetopriemnik unit 121 and 124 of the signal processing, can identify what lighting device 101a-d of the light incident on the receiver 121 of the radiation. The photosensitive sensor 121 in this case is the sensor of the light flux intended to measure light intensity. However you can use other, more sophisticated light sensors (e.g., cameras) to measure other characteristics of light. In addition, possible alternative means of transmission of the identification code, for example amplitude modulation, code sequences, etc. It is well known to experts in the art and conforms to the scope of the invention.

The corresponding unit 130 may be provided in direct connection with each electrical circuit 112 excitation lighting device 101, forming a self-contained unit, see Fig. 2b, or may be provided as a Central control unit for all lighting fixtures, which are shown in Fig. 2a. In alternative implementation, block 130 control is provided in the device 120 selection, see Fig. 2c. In this case, the device of choice �has the additional ability to send the installation to the appropriate electrical circuit 112 excitation.

In addition to the above code modulation, an alternative application of the appropriate frequency PWM to each lighting device, the code can also be sent almost imperceptible, a slight change in the light intensity by changing the duty cycle of the PWM. For individual ID, you can use the modulation scheme multiple access with code division through, for example, amplitude manipulation or Biphase modulation. It is preferable to implement ID in the form of orthogonal codes, since it allows you to easily distinguish them from each other. Since both of these methods can be implemented by changing only at the level of software and hardware, they are very cheap in existing lighting systems.

The light sources contained in these luminaires 101a-d are based on, for example, LEDs, HID lamps (discharge lamps high intensity), halogen lamps, incandescent and/or fluorescent tubular lamps.

Regardless of whether the block 130 control each lighting device in the device selection or a Central control unit, it communicates (wired or wireless) with lighting devices 101a-d to control the light output from the lighting devices 101a-d. In addition, the unit 10 controls can have the block 131 of the processing and the software for controlling lighting from the lighting fixtures. Block 130 control can also be connected to the user interface (not shown) that allows the user to perform direct programming. In addition, the block 130 may be configured to completely turn off each light source through a relay or semiconductor switch, which reduces power consumption in standby mode (not shown).

In addition, the device 120 of choice in this illustrative embodiment, the implementation is a remote control. In alternative embodiments, the device may be a stationary device. However, for simplicity, in the following we will use the term "remote control". The remote control 120 remote control contains the above svetopriemnik 121, block 124 of the signal processing, i.e. the microprocessor, the transmitter 122 to send signals to the lighting devices 101a-d and/or block 130, and the device 123 for user input. Device 123 user input may be, for example, a keyboard, a touchscreen, a means of inputting speech commands, etc. through the device 123 user input the user can enter data, for example data used in the lighting system, the data indicating the need to make a choice�, and selection data.

When a selection of a lighting device, the user (or, alternatively, the firmware in the remote control 120 remote control unit 130 controls) initiates the selection. The user typically initiates the selection by pressing the selection button on the device 123 for user input. Then communication between the controller 120 and remote control unit 130 management through signals, such as radio, lights, etc. remote control sends signals via the transmitter 122 to the corresponding receiver 132 provided in the block 130 control. Alternatively, when the block 130 control is provided in the device 120 selecting, receivers 132 are mounted on luminaires 101a-d to set the value of the excitation lighting.

Block 130 is a control with the ability to identify at least one lighting device 101, the nominal value of the excitation of which is equal to or less than the minimum predetermined value or equal to or greater than the maximum pre-set value. The nominal value of the excitation for the lighting device can be extracted from plants of excitation in block 130 control, for example, the selected cycle, or by measuring the current excited by�Oia, the amplitude of excitation, the current consumption of units in the scheme 112 excitation, etc. in addition, the nominal value of the excitation can be extracted by measuring the current intensity of the light output of a lighting device or can be stored in the device or circuit 112 of the excitation as a result of previous actions excitation. If the identified lighting device, the nominal value of the excitation which is consistent with the identification requirements, the unit 130, the control sets the value of the institution of such identified lighting device on the setpoint excitation. For example, if the lighting device is turned off or has a very low intensity of the light output, then the control unit will set a higher value of excitation, for example 10% of the maximum value of excitation. Similarly, if the lighting device is mounted on a full or nearly full intensity, the control unit will set a lower value of excitation, for example 90% of the maximum value of excitation. The value of excitation is typically set to a value that provides a value of the light intensity of a lighting device that provides the intensity that can transmit the identification code ID of lighting approx�RA by modulating the output light, but which, preferably, will be as close as possible to the nominal value of the excitation, so as not to cause too much light in the room.

The appropriate identification codes IDa-d are transmitted to the light emitted from lighting devices 101a-d. The remote control 120 remote control takes light from lighting devices 101a-d through svetopriemnik 121, and the recorded signal is processed. Then you can select a specific lighting device based on the selected identification codes IDa-d.

According to the embodiment of the lighting system, the predetermined minimum value and predetermined maximum value can be set prior to the selection step, for example, by user input, in the manufacture or during installation of the lighting system in operation.

You can also use some alternative means of determining the set value of the excitation, which will be further discussed below.

According to the embodiment of the lighting system, the set value of the excitation is set equal to a fixed percentage value of the minimum predetermined value (for too low values of excitation) and a fixed percentage value of the maximum Saran�e set value (for too high values of excitation). Alternatively, the percentage depends on the minimum predetermined value or a predetermined maximum value.

According to the embodiment of the lighting system, the predetermined minimum value and predetermined maximum value established during the selection phase. Alternatively, during the selection stage lighting device is installed only one of the options. By way of example, the remote control 120 remote control is made with the ability to prescribe adaptive lighting devices to apply the minimum preset value. Initially, the remote control 120 remote control instructs the lighting devices 101a-d to apply low minimum preset value equal to 1% of the maximum value of excitation. If the remote control 120 remote control cannot register ID code or other lighting device, the remote control requires lighting devices 101a-d to increase the minimum pre-set value to 2%, etc. until you register a sufficient signal containing the ID code expected from the light fixture.

According to the embodiment of the implementation, the remote control 120 remote control is made with the ability to adapt minim�Sal preset value depending on the prevailing signal-to-noise ratio (SNR). For example, a dimly luminous/almost disabled lighting remote control starts with low minimum pre-established value. If the prevailing SNR is too low (because the lighting device is too removed, shielded or nominal excitation for a lighting unit is too low), the remote control 120 remote control sends to the block 130 control instruction to increase the minimum value of the lighting device will not be reached yet reliable means of recording light having a specific ID code. A similar procedure can be applied to lighting with intensity close to the maximum.

According to the embodiment of the lighting system, the remote control 120 remote control configured to send the first command initialization. The user may, for example, press the button on the device 123 for user input. In addition to the block 130 controls, identifying any lighting equipment with too high or too low values of excitation, receiving the first initialization command, all lights except the identified lighting devices transmit their identification codes in the light emitted. Then, the remote control 120 remote control can choose with� one unidentified lighting. Then the user can click a second time the select button in-line remote control configured to send the second initialization command. After receiving the second command, the initialization unit 120, the control is arranged to perform the step of setting values of the excitation of the identified lighting units on a given value of excitation. Then the identified lighting devices are arranged to transmit their identification codes. Thus, the second initialization command is used to allow the user to select a lighting fixture that is mounted on very high or very low nominal value of the excitation, only when he or she really wants to do it.

Alternatively, the setting values of the excitation of the identified lighting devices can be carried out by block 130 selecting, prescribing the identified lighting devices, i.e. lighting devices which are identified as having very low/very high excitation power, completely ignore the first initialization command, but increase/decrease, respectively, the excitation power after taking the second initialization commands from the selector.

In the figures 3a - 3c shows graphs demo�stereoside average intensity, output from the identified lighting unit, with respect to time during the selection. The upper, dashed curve illustrates the average intensity for the lighting device which originally has a too high value of excitation compared with a predetermined maximum value. The lower, solid line illustrates the average intensity for the lighting device which originally has a too low value of excitation compared to a predetermined minimum value. The maximum and minimum predetermined values are shown in the drawings as average intensity (Imaxand Imin. Fig. 3a shows how the average value of the intensity of a lighting device, having too high a nominal average value of the intensity is decreasing during the time of tsand the average value of the intensity of a lighting device, having too low a nominal mean value of intensity increases during the time of ts. The choice of tsusually set in the range of 10-500 MS. Preferably, the selection is set equal to about 200 MS, i.e. short enough to not be noticed by the user, but long enough for reliable reception and time SEL�RA. Then the average intensity returned to the initial nominal values. As a result, the observer can observe the change in light level, which is undesirable. According to Fig. 3b, the difference between the initial nominal average intensity and average intensities established within the time of selection, is much less pronounced. In fact, the average values of intensity are installed near the Imaxand Iminto minimize perceived changes of the average values of light intensity. The values of excitation can also be chosen so that the average values of intensity during the selection were equal to Imaxand Imin. Fig. 3c shows that the average value of the light intensity can gradually return within a specified time interval to a nominal average value of the light intensity (or the value of the excitation corresponding to the average value of light intensity). The fall time during which the values of light intensity can be returned to a nominal average value of light intensity, usually set in the range from 1 to 5, preferably equal to 2 s.

The selection method of a lighting device of the plurality of lighting devices according to the present invention contains the stages on which:

identify at least Odie� the lighting device, the nominal value of the excitation of which is equal to or less than the minimum predetermined value or equal to or greater than the maximum predetermined value,

set the value of the institution of such identified lighting device by the specified value,

passed from each lighting device identification code in the emitted light,

register identification codes, and

choose the lighting device based on the registered identification code.

In addition, a variant of the method contains the stages on which:

provide the first initialization command. In response to this first command, the initialization step of transmitting is performed for all lighting fixtures, in addition to at least one identified lighting device. The method further comprises an optional step in which second issue the initialize command. In response to this second initialization command for at least one identified lighting device is the installation phase and for at least one identified lighting device is carried out during transfer.

In addition, according to the embodiment of the implementation, the method includes, after the selection step, slow the return values of excitation ID�tifizierung lighting device to its initial value within a specified time interval.
