The technical field to which the invention relates

The present invention is mainly directed to the relevant prior art methods and devices for encoding information on the network AC voltage. More specifically, disclosed is varied corresponding to the invention methods and devices relate to the management of lighting devices using the encoded power signal AC.

The level of technology

In various embodiments, the application of lighting devices it is often desirable to adjust the intensity of light generated by one or more light sources. Typically this is performed using a user-controllable devices, commonly referred to as a "dimmer" ("dimmer"), which regulates the power delivered to the source(s) of light. There are many common types of dimmers, which allow the user to adjust the light output of one or more light sources using some type of user interface (for example, by turning the handle, slide the engine and so on, often mounted on the wall near the area in which it is desirable to adjust the light level). The user interface of some dimmers can also be equipped with a switching mechanism/reg the financing, which allows you to instantly turn on or off one or more light sources, as well as to gradually vary the light output when they are enabled.

Many lighting systems for General indoor or outdoor lighting are often powered by a source of alternating current ("AC"), traditionally referred to as "voltage" (e.g., 120 Volts RMS (root mean square current voltage with a frequency of 60 Hz, 220 Volts RMS with a frequency of 50 Hz). Dimmer alternating current (AC) typically receives the mains voltage AC input power, and some common dimmers produce an output alternating current signal having one or more variable parameters, which provide the effect of regulating the average voltage of the output signal (and thus the ability of the output signal AC fail power) in response to bringing the dimmer into action by the user. This output signal of the dimmer in General serves, for example, one or more light sources that are mounted in conventional cartridges or electric valves connected to the output of the dimmer (such cartridges or fittings is sometimes referred to as "contour dimmer").

Traditional dimmers AC may be configured to regulate power supplied to one or more light source is Cove light several different ways. For example, regulation through the user interface may prompt the dimmer switch to increase or decrease the voltage amplitude of the output signal of the dimmer AC. In other configurations, the regulation through the user interface may prompt the dimmer to adjust the duty cycle of the output signal of the dimmer AC (for example, "cutting" parts of cycles of the AC voltage). This method is sometimes called "phase modulation" (based on the regulation of the phase angle of the output signal). Perhaps the most widely used dimmers use this type of TRIAC device (triac), which selectively operates to regulate the business cycle (i.e. the modulation phase angle of the output signal of the dimmer by cutting an ascending part of a sine wave of the AC voltage (that is, after passing through the zero to peak value). In other types of dimmers, which regulate working cycles can be used GTO-thyristors (locking) or IGBT transistors (bipolar transistors with insulated gate), which selectively act to cut down parts of the sine wave of the AC voltage (i.e. after reaching the peak value to zero-crossing).

1 in General, which illustrates some common options dimmers AC. In particular, Figure 1 shows an example of a form 302 waves of the AC voltage (for example, representing the standard mains voltage), which can be fed by one or more common light sources. Figure 1 also shows a generic dimmer 304 AC-driven user interface 305. In the first embodiment discussed above, the dimmer switch 304 is configured to issue an output wave form 308, in which through the user interface 305 may be adjusted amplitude 307 of the output signal of the dimmer. In the second discussed above embodiment, the dimmer switch 304 is configured for the output signal from form 309 waves, in which through the user interface 305 may be adjusted duty cycle 306 form 309 waves.

Both of the above ways have the effect of regulating the average power supplied to the source(s) of light, which, in turn, adjusts the intensity of light generated by the source(s). Incandescent lamps as light sources are particularly well suited for this mode of operation, because they emit light when the filament passes the electrical current in either direction; when regulate the current voltage of the alternating current signal connected to the source(s) (e.g., either by regulating the amplitude of the voltage is agenia, or duty cycle), also changes the power supplied to the light source, and accordingly varies the light output. As regards the manner of adjustment of the operating cycle, the filament of the incandescent lamp as a light source has a thermal inertia and ceases to emit light during short periods of interruption of voltage. Accordingly, the generated light, as perceived by the human eye, does not seem to shimmer when the voltage "cut", but, rather, appears to be changing gradually.

Other common types of dimmers produce an analog signal with a voltage of 0-10 Volts as an output signal in which the voltage output signal proportional to the desired level of dimming (reduction of light intensity). When working such dimmers typically give 0% dimming (i.e. light output "fully enabled")when the output voltage of the dimmer is 10 Volts, and 100%dimming (i.e. light output disabled), when the voltage of the output signal of the dimmer is 0 Volts. In one aspect, these dimmers can be configured to provide various linear or non-linear curves of the output voltage (i.e. the interdependence between the output voltage and the level of dimming).

Still other types of common dimmers, such as dimmers, which uses the t DMX512-a Protocol as a standard lighting control, in which data packets may be transmitted to one or more lighting devices according to one or more data cables (e.g., DMX512 cable). DMX512 data send using voltage levels according to the standard RS-485 cable installation type "Daisy patterns". In a typical DMX512 Protocol data is transferred in batches of 250 kbit/s and are grouped in packages up to 513 bytes, called "frames". The first byte is always a byte "start code", which tells the connected lighting devices, what type of data sent. For example, traditional dimmers as start-code typically use zero.

Still other types of common dimmers produce a variety of types of digital signals corresponding to desired level of dimming. For example, in some traditional dimmers can be used with either the DSI Protocol (serial digital interface)or DALI Protocol (digital addressable lighting interface). Being configured as a DALI controller, dimmer can address and configure the status of each of the dimming of the lighting device in a DALI network. This can be done individually addressing lighting devices in the network or sending digital messages to numerous lighting devices to regulate their light characteristics of the.

Digital lighting technology, i.e. lighting, based on semiconductor light sources such as light emitting diodes (“LED”, LEDs), create a productive alternative to traditional fluorescent lamps, discharge lamps high intensity discharge (HID) and incandescent lamps. Functional advantages and benefits of LEDs include high energy conversion efficiency and optical efficiency, durability, low operating costs and much more. Recent advances in LED technology have led to the emergence of an effective and reliable full spectrum light sources, which provide varying light effects many options for use. Some devices that use these sources arranged in the form of lighting modules, including one or more LEDs can provide light of different colors, e.g. red, green, and blue, and a processor for independent adjustment of the output power of LEDs to generate a multitude of colors and light effects color changing, for example, as discussed in detail in U.S. Patents No. 6016038 and 6211626, incorporated herein by reference. In addition, some ways of deciding on the power to the devices from the AC power source and ease of use of the light source, the Cove light based on light emitting diodes in AC circuits, which return signals other than the standard mains voltage are disclosed in U.S. Patent No. 7038399, which is also incorporated herein by reference.

Thus, there is a need in the technology to more efficiently encode information relating to one or more parameters of the light emitted, for example, light(s) device(s) based LEDs, network AC voltage, thereby producing a coded signal for control and power light(s) device(CTV).

The invention

The present invention is directed to appropriate the invention methods and devices for encoding information on the network AC voltage. For example, the voltage may be encoded for transmission of control information, such as information about dimming, derived from the output signal common dimmer, to produce the encoded power signal AC. In various embodiments implement one or more lighting devices, including lighting based on LEDs, it is possible to supply the working voltage, and manage (e.g., dimming) on the basis of the encoded power signal. In one embodiment, the information may be encoded on a network voltage changes the CSOs current by inverting some of the half-cycles of the line voltage alternating current to generate the encoded power signal AC, with respect to the positive half-cycles to the negative half-cycles, which represents coded information. The encoded information may relate to one or more parameters of the light emitted by the lighting(and) device(s) on the basis of LEDs (e.g., intensity, color, color temperature and so on).

One variant of the invention is directed to a process comprising inferring information about the dimming of the output signal of the dimmer, the encoding network voltage AC information about dimming so as to generate the encoded power signal is an AC current having an RMS value (root mean square RMS), essentially similar to network AC voltage, and regulation, and summarizing operating voltage of at least one light source based at least in part on the encoded power signal AC.

Another variant implementation is directed to a device that includes a first input for receiving the network AC voltage, a second input for receiving the output signal of the dimmer, the output for generating the encoded power signal is an alternating current, and a controller connected to the first input, second input and output, to derive information about the dimming of the output signal dim is EPA and coding mains voltage AC information about dimming so, to generate the encoded power signal AC.

Another variant implementation is directed to a method of encoding information on the network AC voltage. The method includes the management of multiple switches connected to the network AC voltage for inverting at least some of the half-cycles of the line voltage of the alternating current in such a way as to generate the encoded power signal is an alternating current, which is the ratio of the positive half-cycles to the negative half-cycles of the encoded power signal AC.

Another variant implementation is directed to a device that includes multiple switches connected to the network AC voltage, and a controller for obtaining information and managing multiple switches, based on the received information, to invert at least some half-cycles of the line voltage of the alternating current so as to generate the encoded power signal is an alternating current, in which information represents the ratio of the positive half-cycles to the negative half-cycles of the encoded signal.

As used here for the purposes of the present invention, the term "led" ("LED") should understand the AK including any electroluminescent diode or other type of system based on the injection of charge carriers/(p-n)junction, which is capable of generating radiation in response to an electrical signal. Thus, the term "led" ("LED") includes, but is not limited to such a variety of patterns on a semiconductor basis, which emit light in response to electric current, light emitting polymers, organic light emitting diodes (OLED), electroluminescent panels, and the like. In particular, the term led refers to light emitting diodes of all types (including semiconductor and organic light emitting diodes)that can be configured to generate radiation in one or more of the infrared spectrum, ultraviolet spectrum, and different parts of the visible spectrum (mainly including radiation with wavelengths from about 400 nanometers to about 700 nanometers). Some examples of LEDs include, but are not limited to these, various types of infrared LEDs, ultraviolet LEDs, red LEDs, blue LEDs, green LEDs, yellow LEDs, amber LEDs, orange LEDs and white LEDs (optional discussed below). It should also be borne in mind that the LEDs can be configured and/or controlled to generate radiation having different meant what I bandwidth (for example, the values of the full width of the curve at the level of half-maximum, or FWHM) for the spectrum (for example, narrow band, broad band), and diverse dominant wavelengths within this overall color classification.

For example, one embodiment of an led configured to generate essentially white light (for example, white LEDs), can include some crystals which respectively emit different spectra of electroluminescence, which in combination are mixed with the formation of the essentially white light. In yet another embodiment, the led light can be associated with crystalline phosphor, which converts the electroluminescence having a first spectrum in a different second range. In one example of this variant, the electroluminescence having a relatively short wavelength and a spectrum with a narrow band of frequencies, "pumps" crystalline phosphor, which, in turn, emits radiation with a longer wavelength, having a somewhat wider range.

Also it should be understood that the term "led" does not limit the type of physical and/or electrical layout of the led. For example, as discussed above, the led can be related to a single light emitting device having multiple Crist is lly, are configured for the respective different emission spectra of radiation (e.g., which may or may not be managed individually). In addition, the led may be associated with phosphor, which is regarded as an integrated part of the led (for example, some types of white LEDs). In General, the term "led" may refer to the collected design LEDs, individual LEDs, the LEDs with planar mounting, led technology chip-on-board" ("direct mounting on a substrate"), "T-package" LEDs "radial package" light-emitting diodes, high-power designs of LEDs, LEDs, including some types of body parts and/or optical elements (for example, the scattering of the lens), and so on

The term "light source" should be understood as meaning any one or more of the many sources of radiation, including but not limited to those sources based on LEDs (including one or more LEDs as defined above), incandescent sources (e.g., lamps with filament halogen lamps), fluorescent sources, phosphorescent sources, high-intensity discharge sources (e.g., sodium, mercury and metal halide discharge lamps), lasers, other types of electroluminescent history the nicks, sources of pyrogenic nature (e.g., flames), candoluminescence sources (e.g., gas mantle grid sources on the basis of coal arc), photoluminescent sources (for example, gas discharge sources), cathodoluminescence sources using electronic satiation, galvanoplasty sources, crystallochemistry (bioluminescence) sources, killminusnine (scintillation) sources, thermoluminescent sources, triboluminescent sources, sonoluminescent sources, radio-luminescent sources, and luminescent polymers.

This light source may be configured to generate electromagnetic radiation within the visible region of the spectrum outside the visible spectrum, or a combination of both. Therefore, the terms "light" and "radiation" are used here interchangeably. Additionally, the light source may include as an embedded component, one or more filters (e.g., color filters, lenses or other optical components. In addition, it should be understood that the light sources can be configured for a variety of applications, including but not limited to such indication, the removal of images and/or lighting. The light source is a light source, to the of which is specifically configured to generate radiation, having an intensity sufficient for efficient area lighting inside or outside the room. In this context, "sufficient intensity is related to sufficient radiation power in the visible region of the spectrum generated in the space or in the environment (unit "lumen" is often used to represent the overall light output of the light source in all directions, in terms of flux or luminous flux")to provide General illumination (i.e. light, which can be perceived indirectly, and which may be, for example, reflected from one or more of the numerous intermediate surfaces before it will be accepted in whole or in part).

The term "range" should be understood as relating to any one or more frequencies (or wavelengths) radiation generated by one or more light sources. Accordingly, the term "spectrum" refers to frequencies (or wavelengths) not only in the visible region, but also the frequencies (or wavelengths) in the infrared, ultraviolet and other areas of the electromagnetic spectrum. In addition, this range can have a relatively narrow bandwidth (for example, the value of the full width of the curve at the level of half-maximum (FWHM), with essentially little frequency components or wavelengths), or otnositel is a wide band of frequencies (several frequency components or wavelengths, having different relative intensity). It should also be borne in mind that this range may be the result of the superposition of two or more other spectra (for example, by mixing the radiation, respectively, generated numerous light sources).

For the purposes of the present invention, the term "color" is used interchangeably with the term "spectrum". However, the term "color" is mainly used to refer mainly of such property of radiation that can be perceived by an observer (although this use is not intended to limit the scope of this term). Accordingly, the terms "different colors" indirectly indicate numerous spectra with different components of their wave lengths and/or widths of the frequency bands. You should also take into account that the term "color" may be used in connection with both white and non-white light.

The term "color temperature" is mainly used here in connection with white light, although such use does not imply a limitation of the scope of this term. Color temperature is essentially relates to the specific sotoodehnia or tone (e.g., reddish, bluish white light. The color temperature of this sample radiation is traditionally characterized according to the temperature in degrees Kelvin (K) radiation is non black body, which emits essentially the same spectrum, as discussed sample radiation. The color temperature of the radiating black body basically are in the range of from about 700K (typically considered as the first visible to the human eye) to more 10000K; white light is often perceived color when temperatures above 1500-2000K.

Lower color temperatures generally correspond to white light, with a more pronounced red component or warmer in feeling", while higher color temperatures generally correspond to a white color, with more significant blue component or cooler according to the sense". As an example, fire has a color temperature of approximately 1800K, the common incandescent lamp has a color temperature of approximately 2848K, daylight early in the morning has a color temperature of about 3000K, and tightened by clouds at midday sky has a color temperature of approximately 10000K. Color image considered when illuminated with white light having a color temperature of about 3000K, has a relatively reddish tint, whereas the same color image under white light having a color temperature of approximately 10000K, has a relatively bluish tint.

The term "OS is michelina valve" is used here to indicate the version or build one or more lighting devices with specific design parameters, in the layout node or module. The term "lighting device" is used here to denote a device that includes one or more light sources of the same or of different types. This lighting device can be any of the varied mounting configurations for the source(s) of light, hull/reinforcing structures and forms, and/or configurations of the electrical and mechanical connections. Additionally, this lighting device may not necessarily be associated (e.g., enabled, connected and/or installed together with various other components (e.g., control circuit)related to the source(s) of light. The term "lighting device on the basis of light" relates to a lighting device that includes one or more light sources based on LEDs, as discussed above, separately or in combination with other light sources, which are not LEDs. "Multi-channel" lighting device relates to a lighting device based on led or non led that includes at least two light sources configured for the corresponding generating different spectra of radiation, in which the range of each of the different sources can be named as "the channel" mn is gokayleego lighting device.

The term "controller" is used here mainly to describe the various devices related to the one or more light sources. The controller can be executed in a variety of ways (e.g., such as within a prescribed instrument design) to perform various functions discussed here. "Processor" is one example of a controller that uses one or more microprocessors that can be programmed using software (e.g., microcode) to perform discussed here a variety of functions. The controller can be executed using processor or without, and can also be configured as a combination of appropriate hardware to perform some functions, and a processor (for example, one or more programmed microprocessors and associated electrical circuit) to perform other functions. Examples of the components of the controller, which can be used in different variants of implementation of the present invention include, but are not limited to those commonly used microprocessors, problem-oriented integrated circuit (ASIC) and the base matrix crystals (FPGA).

In various versions of the processor or controller can be svazas one or more media data (generally referred to here as "memory", for example, volatile and non-volatile storage such as random access memory (RAM), programmable permanent memory (PROM), erasable programmable permanent memory (EPROM) and electrically erasable programmable permanent memory (EEPROM), floppy diskettes, CD-ROMs, optical disks, magnetic tape etc). In some embodiments, execution of the media data may be encoded by one or more programs that, when executed by one or more processors and/or controllers, perform at least some of the functions discussed here. Various data carriers can be fixed inside of a processor or controller, or may be portable, such that one or more programs that are stored on them can be loaded into the processor or controller to implement here discuss various aspects of the present invention. The terms "program" or "computer program" is used here in a very General sense to refer to any type of computer instruction set (e.g., software or microcode)that can be applied for programming one or more processors or controllers.

The term "addressable" is used here for additional is the device (for example, light source in General, the lighting unit or fixture, a controller or processor associated with the one or more light sources or lighting devices, the other related to those neosocialism devices and so on), which is configured to receive information (for example, data intended for multiple devices, including himself, and for selective response to a particular information intended for him. The term "addressable" is often used in connection with networked environment (or "net", more discussed below), in which multiple devices are connected together through some communication medium or environment.

In one network embodiment, one or more devices connected to the network, can serve as a controller for one or more other devices connected to the network (for example, on a "master-slave"). In yet another embodiment, the network environment may include one or more of the assigned controllers configured to control one or more devices connected to the network. In General, each of the multiple devices connected to the network can have access to the data that are present in the communicative environment or environments; however, this device can be"addressed" in the sense that it is configured for selective communication with the network (i.e. receiving data from the network and/or data transmission in the network), based on, for example, on one or more specific identifiers (e.g. "address")assigned to it.

The term "network"as used herein refers to any mutual connection between two or more devices (including controllers or processors), which simplifies the transfer of information (for example, device management, data storage, data exchange, etc) between any two or more devices and/or among multiple devices connected to the network. As should be readily understood, various variants of networks suitable for mutual connection of multiple devices can include any of the diverse topologies of the network, and to use any of the numerous communication protocols. Additionally, in various networks according to the present invention, any one connection between two devices can be assigned to represent a connection between two systems, or, alternatively, unassigned connection. In addition to the transfer of the information intended for the two devices, such unassigned connection can carry information, not necessarily intended for one of the two devices (for example, open a network connection). Further, it should be readily understood that a variety of network devices, as discussed here, may use one or more of wireless, wire-cable and/or fiber optic communication lines to facilitate the transfer of information over a network.

The term "user interface"as used here, refers to the interaction between the person as a user and one or more devices that enables communication between the user and the device(s). Examples of user interfaces that can be applied in different variants of implementation of the present invention include, but are not limited to such, switches, potentiometers, buttons, coronaviridae, sliders, mouse, keyboard, digital keyboard, various types of gaming consoles (e.g., joysticks, trackballs, screens, various types of graphical user interfaces (GUI), touch screens, microphones, and other types of sensors that can take a form supplied by the human input signals and to generate a signal in response to them.

It should be clear that all combinations of the above principles and additional ideas discussed in much greater detail below (provided that the principles are not mutually contradictory), are considered as part of the subject invention, unveiled here. In particular, all combinations of the declared object of the invention is shown in the end of the description of the present invention, are considered as part of the presented subject matter.

Detailed description

The light sources based on LEDs become increasingly popular due to their relatively high efficiency, high intensity, low cost and high level of controllability, compared to traditional incandescent or fluorescent light sources. While for control of conventional light sources such as incandescent lamps powered from an AC source, use different types of common dimmers for AC, some examples of commonly used dimmers can also be used to control individually packaged lighting devices based on light-emitting diodes, as discussed, for example, in U.S. Patent No. 7038399.

Ka is discussed above in connection with FIGURE 1, inexpensive commercially available on the market dimmers do not necessarily generate the power signal is an alternating current having the same or essentially the same mean-square RMS value of the mains voltage AC. Applicants have recognized and understood that in some circumstances, it may be a problem conclusions as operating power, and information about dimming, on numerous lighting devices/devices based on LEDs included in the same circuit of the dimmer. Applicants also recognized and understood that due to the large variety of cheap common dimmers, readily available on the market, it would be advantageous to have an interface that simplifies the compatibility between different types of dimmers and one or more lighting devices configured to receive operating power from the mains AC voltage.

More generally, Applicants have recognized and understood that it would be useful to encode various types of information on the network AC voltage to generate the encoded power signal is an alternating current, which can be used to summarize how the full operating power and control information to a variety of electrical devices.

In light of the foregoing, some embodiments of altoadige invention is directed to methods and devices for encoding the mains voltage AC information about dimming, derived from the output signal common dimmer to generate power AC signal, the encoded information about dimming, in which the encoded power signal AC is essentially similar to the RMS value as the voltage of alternating current.

FIGURE 2 illustrates a device 50 for encoding information according to one variant of implementation of the present invention. The device includes a controller 100, the first input 122 for receiving the line voltage 105 alternating current and a second input 124 for receiving the output signal 112 generated by the source 110 information. In one aspect of the mains voltage 105 AC can be summed up by connecting the first input 122 to a standard power outlet (for example, the first input 122 may be performed in a standard plug). The device 50 further includes an output 126 for supplying the encoded output power signal 130 AC. In one aspect, the encoded power signal 130 AC may be essentially similar to the RMS value as the supply voltage 105 AC.

In some embodiments, the implementation of the source 110 information may be conventional dimmer, such as described above dimmers (for example, in connection with FIGURE 1). Accordingly, it should be understood, in various embodiments, implementation examples of possible output signals 112 include, but are not limited to such, the amplitude-modulated alternating current signal, modulated duty cycle (phase angle) of the alternating current signal, 0-10 V analog DC signal, the packet control data according to the DMX512 Protocol, or a digital signal, such as DSI or DALI signal, for entering information about the dimming controller 100. More generally, it should be understood that the source 110 information according to other variants of implementation may issue various types of information, other than information about dimming, the controller 100 with the output signal 112 (e.g., the color tone of light or color temperature), or information, which includes a combination of information about dimming and other information.

According to some variants of implementation of the present invention, the controller 100 may be configured to process a single type of output signal 112. In other embodiments, implementation of the present invention, the controller 100 may be configured to communicate with any one or more identical or different sources 110 information, which can issue different types/formats of the output signals 112, such as the aforementioned signals or other. One option is to implement many different sources of information can issue corresponding substantially different output signals, the controller 100 may be configured to select any of several possible output signals at any given time, to simplify the coding of a particular type of information and/or a particular type/format of the output signal. For example, the controller 100 may be connected to the first dimmer, which produces a modulated duty cycle of the alternating current signal, and/or the second dimmer, which produces a digital signal based on the DALI Protocol. In one exemplary embodiment, as shown in FIGURE 2, the choice between the numerous sources of information/output signals can be done by using the optional user interface 220 connected to the controller 100.

According to one variant of implementation, the controller 100 may include various components that are designed to simplify the encoding of information about dimming and/or other information sent in the output signal 112 to the voltage 105 AC, as shown in FIGURE 3. For example, the controller 100 may include discretization 200 for sampling the output signal 112, and the circuit 210 encoding to isolate the mains voltage 105 AC output from the encoded power signal 130 AC, and to encode information about dimming and/or other information in the power signal is an alternating current.

In one embodiment, discretization 200 may include equivalent load 150. In General, equivalent to the load 150 may be a power resistor, or any other suitable resistive device, including but not limited to such, the passive resistive device and the active resistive device. In one embodiment, the equivalent load 150 may have a fixed resistance value, and may be selected so that the power consumed by the load 150, was less than 8 Watts. In other embodiments, the implementation of a resistance value equivalent to the load 150 may be adjusted to reduce power consumed by the load 150, at the same time still maintaining the proper functioning of the source 110 information. For example, some common dimmers require that the dimmer was connected load having at least a minimum resistance value, to produce an output signal that accurately reflects information about dimming sent by the dimmer. In such scenarios, the implementation of the adjustable resistance value can be configured by the user by adjusting a button, switch or any other suitable user interface (e.g., user is lsim interface 220), provided to the controller 100. One example of a suitable equivalent load 150 includes, but is not limited to such a device for simulating minimum load LUT-LBX, manufactured by Lutron Electronics Company, Inc. in Coopersburg, Pennsylvania.

In some embodiments of the invention, the controller 100 may additionally include a microprocessor 170, coupled with discretization 200, which displays processed information signal 175 to the circuit 210 encoding. In one embodiment, the microprocessor 170 may be executed as part of an integrated circuit in which an integrated circuit memory chip also includes other components that support the microprocessor, such as at least one memory device, for storing one or more computer programs, which are then executed by the microprocessor 170, controlling the operation of the various components of the controller 100. In yet another embodiment, shown in FIGURE 4, discretization 200 may include an integrated circuit with a microprocessor 170, having a universal asynchronous receiver transmitter (UART) 510 and block 520 signal processing for supplying the processed information signal 175 to the circuit 210 encoding.

For variants, in which the output signal 112 is an analog signal, discrete the ATOR may further include an analog-to-digital Converter 160 for sampling the output signal (for example, voltage is equivalent to the load 150). For example, as shown in FIGURE 5, the equivalent load 150 may be a circuit of the voltage divider to which is fed the output signal 112. The circuit of the voltage divider may include at least two resistive component connected in series, and an analog-to-digital Converter 160 may be configured to sample the voltage of one of the resistive components or both thereof. In one embodiment, the microprocessor 170 and associated memory components (not shown) can calculate the time-averaged discretized voltage for supplying as an input signal to the circuit 210 encoding, in which the time-averaged voltage contains information encoded on the network voltage 105 AC. In an alternative embodiment, the wave form of the voltage of the output signal 112 can be directly discretized analog-to-digital Converter 160 (e.g., without the introduction of equivalent load) and processed by the microprocessor 170 and associated memory components. Analysis of the waveform of the voltage microprocessor 170 may detect changes in the characteristics of the waveform voltage. In this alternative embodiment, one or more aspects of the detected change is tions characteristics may represent encoded information and may be issued by the microprocessor 170 to the circuit 210 encoding. You should take into account that can be applied to any other suitable combination of resistive elements and measurement analog-to-digital Converter 160, and embodiments of the invention in this regard are not limited to.

In yet another additional embodiment of the analog-to-digital Converter 160 may not discretize (directly or indirectly) output signal 112, as described above, but may instead include a diagram of the threshold detection level. The scheme is a threshold level of detection may include a comparator and/or other circuit elements to facilitate the detection threshold level of the output signal 112. For example, the output signal 112 can be served as a first input to a comparator that produces a particular logical state (e.g., binary value unit), when the absolute value of the output signal 112 voltage is higher than a threshold voltage (for example, 2 Volts), the output as a second input to the comparator. The desired threshold voltage for the circuit threshold detection level can be determined by known double the voltage amplitude of the network voltage 105 AC. Since the frequency of the mains voltage is also known, the synchronization information based on the generation of the digital to the CSO output signal from the circuit threshold detection level, may be issued in the form of processed information signal 175 to the circuit 210 encoding. For example, timing information may be derived by sampling the digital signal output circuit threshold level of detection. Alternatively, the output signal of the circuit threshold detection level can be used as the control input for the timer on the microcontroller, and the microcontroller generates the processed information signal 175 to the circuit 210 encoding. It should be understood that any suitable combination of circuit elements can be used to detect a threshold level of the output signal 112 and to generate timing information, and embodiments of the invention are not limited in this respect.

According to other variants of execution, in which the output signal 112 is a digital signal (for example, DSI or DALI signal), involving 4, universal asynchronous receiver / transmitter (UART) 510 can discretize the digital output signal 112 and output a sampled digital output signal at block 520 signal processing. The signal processing unit may then process the sampled digital output signal to generate the information signal 175. The mapping between the discretized digital output signal and the information signal 175 may be linear or nonlinear, and embodiments of the invention are not limited in this respect.

In one embodiment of the present invention, the microprocessor 170 may be configured for executing one or more computer programs. One or more computer programs may include a series of commands that, when executed by the microprocessor 170, the discretized process the output signal of the analog-to-digital Converter 160 or discretized output signal 112, to issue an information signal 175, which, in turn, can be encoded circuit 210 encoding. The interdependence between the signal in the microprocessor 170, and an information signal 175, issued by the microprocessor 170 may be linear or nonlinear, and embodiments of the invention are not limited in this respect. For example, one typical characteristic darkening of traditional incandescent bulbs is that the light generated by the incandescent lamp becomes warmer color temperature (more reddish) decreasing the strength of the light source. In one embodiment, the relationship between signal to the microprocessor 170, and an information signal 175 may be, in particular, configured to simulate this effect in the lighting device OS is ove LEDs by introducing information about the intensity and color/color temperature information signal 175 based on the information about dimming delivered by the output signal 112. In other examples, the non-linear dependence between the discretized parameters of the output signal 112 and an information signal 175 may be used to accomplish a variety ordered by the user of the lighting conditions and lighting effects.

In yet another embodiment, the microprocessor 170 may be configured for executing one or more computer programs to perform the calibration method for calculating at least some of the errors common dimmers, when they are set to the position "a fully on or fully off. For example, if the source 110 is a conventional dimmer, and the output signal 112 is a 0-10 volt analog signal DC, the variances of characteristics from one scene to another, which appeared in the process of their manufacture, can determine that the dimmer does not issue exactly 0 Volts when it is displayed in the position of "fully off", or exactly 10 Volts, when he's put in a position fully inclusive. By calibration of the output signal 112 dynamic range of the real scene, which is first powered encoded output power signal 130 AC, can be extended, and may improve the accuracy of the parameters of the lower level and/or higher level.

In yet another additional embodiment, the microprocessor 170 may be configured for executing one or more computer programs that facilitate interpolation (e.g., smoothing) between the discretized levels of dimming, and in particular, when information about dimming, derived from the output signal 112, exhibits one or more jumps in the level of dimming. For example, an information signal 175 may be based, at least in part, on prior information about dimming directed to the microprocessor 170 to provide a smooth transition between levels of dimming, which prescribed encoded power signal 130 AC. In other embodiments, the implementation of smoothing between the levels of dimming can be achieved by introducing one or more additional circuit elements such as a capacitor, connected to an equivalent load 150.

In one embodiment of the present invention, as shown in FIGURE 3, the circuit 210 encoding may include an isolation circuit 180 to isolate the mains voltage 105 AC output from the encoded power signal 130 AC, and the encoder 140 to obtain information is sent to the steering signal 175 from the microprocessor 170 and coding information on a network voltage 105 to generate the encoded power signal 130. In one embodiment of the invention, a decoupling circuit 180 includes a transformer to provide electromagnetic isolation between the input mains voltage 105 and the output encoded power signal 130 AC. However, it should be understood that, while the above-described decoupling circuit 180 includes a tool electromagnetic isolation, various embodiments of the invention can include any suitable insulating devices, including but not limited to such, optical and/or capacitive insulating device, and the invention in this regard is not limited.

Information can be encoded on a network voltage using any suitable Protocol. In some embodiments of the invention, the coding information may be performed using a Protocol based on PLC ("the transfer signal wiring"). PLC protocols are often used to control devices in the home, and act by modulating the information in the carrier frequency between 20 and 200 kHz in an existing home wiring (i.e. wire wiring that delivers the standard mains voltage AC). One example of such a control Protocol is the programming language X10. In a typical ispolnenii managed device (for example, lamps, thermostats, hot water Jacuzzi, etc.) is connected to the X10 receiver, which, in turn, connected to a conventional power outlet that is connected to the wiring network of the AC voltage. The device that you want to manage, assign a specific address. X10-transmitter/controller is connected to another outlet connected to the wiring of the mains voltage, and exchanges control commands (for example, to enable or disable the device) in the same wiring, supply voltage, with one or more X10 receivers, guided, at least partially, attributed(s) address(s).

In traditional X10 Protocol information about addressing and control commands are encoded as digital data on a carrier frequency of 120 Hz, which is transmitted in the form of packages at the moment (or in the vicinity thereof) of the transition network of the AC voltage through zero, and at each passage through zero is transmitted one bit. To control X10-X10 compatible devices-transmitter/controller transmits information about the addressing device, and then in subsequent transmissions sends a control command that defines which command should be executed by the device. In one example, the user may wish to include X10-compatible osvetitelem the e device who has been assigned the address A25. To activate the lighting device X10 controller must transmit a message, such as "select A25", followed by the message "enable". Since the data is transmitted only when the voltage transitions through zero, the data transfer rate using the X10 Protocol be on the order of 20 bits per second. Accordingly, the transmission device address and the command may take approximately 0,75 seconds.

In addition, the relatively high carrier frequency used in the X10 communications cannot be effectively transferred through power transformers (for example, in the decoupling circuit 180), so that together with decoupling circuit 180 X10-coding allows you to effectively isolate the mains voltage 105 AC from the encoded power signal 130 AC. Thus, according to one variant of implementation, the methods and devices according to the present invention facilitate the compatibility of the various light sources based on LEDs and lighting devices with X10 and other PLC communication protocols, which send control information in connection with the network AC voltage.

You should take into account that the specific example of the X10 as an example based on PLC Protocol for encoding information on the set is the first AC voltage is shown primarily to illustrate one type of PLC Protocol encoding, and embodiments of the invention are not limited in this respect. For example, can be used other PLC control protocols, including but not limited to such systems, home automation KNX, INSTEON, BACnet and LonWorks, or any other suitable Protocol for encoding information on the network AC voltage.

Alternative execution circuit 210 encoding according to one variant embodiment of the invention shown in FIG.6. In this embodiment, as the isolation between the input mains voltage and coded output power alternating current signal, and encoding information are performed with the use of multiple switches 190, 192, 194 and 196, which are controlled by the microprocessor 170. According to one variant of the invention, the switches form the diagram of H-bridge (otherwise known as "full bridge"), as shown in FIG.6. Two wires of the normal mains voltage 105 AC serves current to the upper and lower branches of the circuit H-bridge, and the encoded output power signal 130 AC depends on the state of the switches 190, 192, 194 and 196.

To obtain the encoded output power signal 130 AC output H-bridge using mains voltage 105 AC switch is catelani control mode alternating pairs. What a pair of switches is closed at any given time, and the phase of the input voltage 105 AC, determines the polarity of the encoded output power signal 130 AC. For example, to play a sine wave encoded output power of an alternating current signal, as shown in FIGA (i.e. identical voltage 105 AC)must be closed or a pair of switches 190-192, or a pair of switches 194-196, while the other pair of switches must be open. Alternatively, if a pair of switches 190-192 and 194-196 alternately switched during each zero-crossing of the waveform of the input mains voltage AC (i.e. each politicl), then the diagram H-bridge should work essentially as polevanov rectifier to generate the waveform shown in FIGV.

In one embodiment of the invention, the microprocessor 170 controls the synchronization of the switching of the pairs of switches 190-192 and 194-196, based at least in part, on information derived from the output signal 112. Assume that the wave form shown in FIGS, is a desirable coded output power signal 130 AC. At time T3the microprocessor 170 may "flip" politicalhumor mains voltage 105. To accomplish this, the microprocessor 170 may send control commands to the circuit H-bridge at time T3to switch pairs, which are closed (for example, to switch from 190-192 on 194-196), and then at time T4send control commands to switch pairs again (i.e. to switch from 194-196 on 190-192). Similarly, to generate the encoded output power signal 130 AC current corresponding to the waveform shown in .7D, the microprocessor 170 may send control commands to the circuit H-bridge at time T3T4T5and T6to switch pairs, which are closed.

In one embodiment of the invention, information may be encoded on the network AC voltage proportional to the ratio of the positive half-cycles to the negative half-cycles of the output power signal 130 AC for some period of time. For example, the encoded power signal is an alternating current, shown in FIGA, has positive politicla negative politicla equal to 1:1. In some embodiments, the implementation, where the encoded information is information about dimming, this relation can refer to a 100%level of dimming. On the contrary, the encoded power signal is an alternating current, is provided in FIGS, has the ratio of 1:2, and as such, it can match the level of the dimming 50%. Similarly, the encoded power signal is an alternating current, shown in .7D has a ratio of 1:5, and it can match the level dimmable to 20%.

The exemplary waveforms shown in FIGA-7D show only three cycles of the encoded output power signal 130 AC, during which the ratio of the positive half-cycles to the negative half-cycles are defined. It should be understood that there can be any number of cycles, during which can be performed coding, and the more cycles, within which is the encoding, the higher could be the resolution encoded information (e.g., more programmed levels of dimming). However, the choice of a larger number of cycles within which perform coding, also leads to reduced speed of encoding. In some exemplary embodiments of the invention, it is desirable balance between a relatively low coding rate, and obtaining a sufficient number of dimming levels, to achieve dimming, applicable in practical use cases. Therefore, in some exemplary embodiments, the implementation of the encoding can be performed within the range of 5-10 cycles to respectively receive 5-10 RA is personal levels of dimming.

You should take into account that in various embodiments of the invention the switches in the circuit H-bridge shown in FIG.6, can be performed in any suitable type of switch, including, but not limited to, bipolar junction transistors (BJT), metal oxide field effect transistors (MOSFET), bipolar transistors (IGBT) and a silicon controlled diode rectifiers (SCR).

FIG illustrates that, according to some versions of the invention, one or more lighting devices/devices 800, 810, 820-based LEDs can be connected to the controller 100 to provide both the capacity and information to be delivered coded output power signal 130 AC to adjust the characteristics of generating light of one or more lighting devices/appliances. In order to effectively modulate their characteristics generate light, each lighting device may include at least one decoder (e.g., decoders 802, 812, and 822) for demodulation of the encoded output power signal 130 AC. Demodulation may be performed in any of several ways, depending on the method/Protocol of encoding used to encode the power signal 130, and the choices done by the means of the invention are not limited in this respect.

In some variants, as discussed above, information may be encoded on the network AC voltage using a PLC Protocol, such as the X10 Protocol. Decoders 802, 812, 822, associated with each lighting device 800, 810 and 820 may be configured as X10 receivers for the demodulation X10-information from the encoded output power signal 130 AC, and information of the lighting device to change its characteristics generate light, as desired.

In other versions of the information can be encoded on the network AC voltage as the ratio of positive to negative half-cycles, as described above in connection with 6 and 7, and light(s) device(s) may(gut) to decode the information on the encoded output power signal 130 AC by calculating the relationship of the positive to the negative half-cycles within a predefined time interval. In one embodiment, the decoders (e.g., decoders 802, 812, 822) can monitor the voltage transitions through zero in the coded output power signal 130 AC to determine the polarity of the signal as in directly what is happening, and/or subsequent zero crossing. Integrating pre-ass the frame number of cycles light(s) device(s) may(gut) to define the desired level of dimming (i.e., if the information represents the dimming information). In an alternative embodiment, the decoder can determine the ratio of positive to negative half-cycles discretization of the encoded output power signal 130 AC at a higher speed rate than the frequency of the signal (for example, faster than 60 Hz), and to determine changes in one or more characteristics of the alternating current signal. For example, a typical sampling rate may be 120 Hz.

In fact, the encoding and decoding can be performed by any means to the extent and circuit 210 encoding, and lighting(s) device(s)connected power signal 130, see General Protocol for determining, as the ratio of half-cycles can be calculated to derive an appropriate control signal to the led(s). It should be understood that it may be applied by any other suitable method of determining the ratio of positive to negative half-cycles in the coded output power signal AC and the above specific examples are given only for purposes of illustration, but not limitation.

In other additional embodiments, the implementation of numerous characteristics of generating light of one or more lighting devices based on led Halloween gift is s can be changed in response to receiving information, encoded on the network AC voltage. For example, in one embodiment, one or more lighting devices based on light emitting diodes attached to the controller 100 may be configured essentially to recreate the lighting characteristics of light traditional incandescent bulbs, when light(s) device(s) provided(s) information about dimming by the encoded output power signal 130 AC. In one aspect of this variant implementation this can be accomplished by simultaneous variation of the intensity and color/color temperature of the light generated by the lighting devices based on light-emitting diodes.

More specifically, in the traditional incandescent color temperature of the light emitted mainly reduced by decreasing the power dissipated by the light source (for example, at lower levels of intensity, correlated color temperature of the light produced may be about C, whereas the correlated color temperature of light at higher intensities may be closer to 3200K). This explains why light bulbs tend to be more red, when the light source power is reduced. Accordingly, in one embodiment, the lighting device based on led Halloween gift is s can be configured so that that a single adjustment of the dimmer can be used for simultaneous changes in both intensity and color of the light source to provide a relatively high correlated color temperature at higher intensities (for example, when the dimmer generates essentially "full" power), and give a lower correlated temperature at low intensities to simulate light bulbs.
