The technical field TO WHICH the INVENTION RELATES

The present invention is directed generally to the control of solid-state lighting devices. More specifically, various claimed methods and devices disclosed herein relate to the adjustment range of light output of solid-state lighting system to compensate for the switching ranges of the various regulators-light conditions.

The LEVEL of TECHNOLOGY

Digital or solid-state lighting technologies, i.e. illumination based on semiconductor light sources such as light emitting diodes (LEDs), offer a competitive alternative to traditional fluorescent lamps, discharge lamps high intensity (GWI) and incandescent lamps. Functional advantages and benefits of LED include high power conversion and optical efficiency, long service life, low operating costs and many others. Recent advances in LED technology have provided efficient and reliable full-spectrum light sources that allow various lighting effects in many applications.

Some of the devices of these sources are characterized by the lighting module, including one or more LED, capable of producing white and/or other light colors, such as red, W�colours green and blue, as well as a control unit or processing device to control the output of the LED to generate a variety of colors and svetoizluchayuschie lighting effects, for example as described in U.S. patent No. 6016038 and 6211626. LED technology includes an illuminating device supplied with power line voltage, such as ESSENTIALWHITE series manufactured by Philips Color Kinetics. Such lighting devices can be adjustable with the help of technology, the dimmer of the trailing edge, such as a dimmer type low voltage (NAN) for line voltage VH (or introduced mains voltage).

Many lights use a dimmer. Conventional dimmers work well with incandescent lamps (electric and halogen bulbs). However, problems happen with other types of electric lamps, including compact fluorescent light bulb (CFLs), halogen lamps low voltage electronic switching devices and solid-state lighting lamps (TTO), such as LED and OLED. Halogen lamps low voltage electronic switching devices, in particular, can be switched using a special dimming ballasts, such as dimmers type CFLs or resistive�about-capacitive (RC) dimming ballasts, working properly with a load having an input circuit correction (PFC) the power factor.

Traditional dimmers usually cut off a portion of each of the waveforms of the input mains voltage and transmit the remaining part of the waveform to a light unit. The dimmer leading edge or front of the phase cuts off the leading edge of the waveform of the voltage signal. The dimmer of the trailing edge or reverse phase cuts off the trailing edge of the waveform of the voltage signal. Electronic loads, such as excitatory signals LED, usually work better with the dimmer of the trailing edge.

Unlike devices with incandescent and other resistive lighting devices which respond naturally without error to intermittent sinusoidal wave form "fusionretail" dimmer, LED and other solid-state lighting load can cause a number of problems like loss of bits of the lower edge, turn the triac, the problems with minimal load, the shimmer of the upper edge, and large steps in the derivation of light, if placed on a terminating phase of the dimmer.

Additionally, the adjustment ranges of light (i.e., the range between the minimum and maximum angles of the phase controller� light) can vary depending on the dimmer, depending on various factors, such as the model and/or type of dimmer. For example, among conventional dimmer, root mean square (RMS) voltage, derived by the regulator and monitored at the input of the power Converter may vary from 45 percent to 20 percent of completely uninterrupted electrical networks with minimum settings of the dimmer (corresponding to the minimum phase angles of the dimmer and lowest levels of light output), and from 75 percent to 95 percent of completely uninterrupted electric networks by the maximum setting of the dimmer (corresponding to the maximum phase angles of the dimmer and the highest levels of light output). These differences lead to different levels of the switch and the range switch, depending on the switching device.

Fig. 1A and 1B depict illustrative of intermittent waveforms of the rectified input mains voltage by the power Converter from the different types of dimmer (controller And light controller To light), respectively, are configured at their minimum settings of the dimmer. As shown in Fig. 1A and 1B, the phase angle regulator And light at its minimum setting controller OS�estnosti more what is the phase angle regulator In illumination at its minimum setting of the dimmer. For example, the controller And the light may be dimmer 6615-POW, and the regulator In the light may be dimmer DVELV-303P, which produces Leviton Manufacturing Co, the regulator And the light slowly lowers the light level to 17 percent, and the regulator In the light slowly lowers the light level to 6 percent. The phase angle of each dimmer corresponds to the "working time" that is such a length of time when each waveform discontinuous waveform of the rectified input mains voltage is not equal to zero. "Working time" can be defined, for example, the time duration when the electronic switch of the corresponding dimmer included (i.e., only allows current to flow to the power Converter). With reference to Fig. 1A and 1B, the working time Tonacontroller And light more than the working time Tonbthe regulator In the light.

Accordingly, the controller And the light provides a larger RMS voltage at the inverter input power than the regulator In the light, that leads to greater output of light from the solid-state lighting load, the controller And evidencecentered at its minimum setting of the dimmer, not when the controller is In the illumination configured at its minimum setting of the dimmer. Because of the nonlinear nature of the response of human eye to the light intensity, the difference between the two lowest intensity of the dimmer will be huge. A similar situation exists with respect to the maximum settings And lighting and control In illumination.

Summary of the INVENTION

The present disclosure is directed to appropriate the invention methods and devices for determining the minimum and maximum phase angle of the dimmer and regulation of the output power to the load solid-state lighting, based on the maximum and minimum phase angles of the dimmer to control the amount of light extracted by solid-state lighting load in response to the maximum and minimum phase angles of the dimmer.

In General, in one aspect, a method is provided for controlling the power Converter to provide a uniform adjustment range light load on solid-state lighting, regardless of the type of dimmer. The method includes determining minimum and maximum phase angle of the dimmer that is associated with the power Converter during works� loads solid-state lighting, and dynamic regulation of the output power of the power Converter based on the detected minimum and maximum phase angle of the dimmer. Regulated output power of the power Converter adjusts the light level of the upper edge, the output from the solid-state lighting load at maximum phase angle to match the predetermined value of the upper edge, and adjusts the light level of the lower edge output from the solid-state lighting load at minimum phase angle to match the predetermined value of the lower edge.

In another aspect, the method provides a uniform adjustment range light load solid-state lighting for many different types of dimming ballasts. The method includes initially setting the minimum phase angle corresponding to the minimum setting of the dimmer, and the maximum phase angle corresponding to the maximum setting of the dimmer; detecting the phase angle of the dimmer based on the rectified input mains voltage; determining whether the detected phase angle less than the initial minimum phase angle; and setting the detected phase angle as the minimum phase angle when the detected�th phase angle less than the initial minimum phase angle. The method further includes determining whether the detected phase angle is greater than the initial maximum phase angle; and setting the detected phase angle as the maximum phase angle when the detected phase angle is greater than the initial maximum phase angle. Function light output range is determined from the minimum phase angle and the maximum phase angle to determine the value of control signal power. The signal power control controls the output power delivered by the power Converter to the load solid-state lighting, so that the load of solid-state lighting displays pre-defined minimum level of light in response to the minimum phase angle and outputs the predetermined maximum level of light in response to the maximum phase angle.

In another aspect, is provided a system of controlling power delivered to the load solid-state lighting. The system includes a power Converter and a circuit for detection of the phase angle of the dimmer. A power Converter configured to deliver a preset nominal power to the load solid-state lighting in response to the rectified input voltage coming from the mains voltage. The arc detection circuit� phase dimmer is arranged to determine if you have connected a dimmer between the network voltage and the power Converter to generate the control signal output, having a first value when the dimmer is present and having a second value when the dimmer is missing, and to provide a signal power control in a power Converter. The power Converter increases the output by the compensation value in response to the first value of the control signal output, and increased output power equal to the nominal capacity.

The IMPLEMENTATION of the INVENTION

In the subsequent disclosure of the invention, for the purpose of explanation but not limitation, are set forth illustrative embodiments of revealing specific details to provide a thorough understanding of the present invention. However, specialists in the art it will be obvious that other variants of implementation in accordance with the present disclosure that may deviate from the specific details disclosed herein are included in the scope of the applied claims. Moreover, descriptions of well-known applications various�and in ways that may be missed, in order to facilitate understanding of the present embodiments. Such methods and devices are obviously within the scope of these ideas.

Applicants determined that it would be advantageous to provide a scheme capable of handling the power output from the power Converter to the load solid-state lighting, to compensate for differences between the maximum and minimum level of regulation, provided with different dimming ballasts, thus providing a uniform upper and lower levels of light output by the solid-state lighting load.

Usually, it is desirable to have the same amount of light output from the solid-state lighting load at maximum and minimum settings of the dimmer, respectively, regardless of the type of dimmer (for example, the model and manufacturer), which is joined to the solid-state lighting load. In various embodiments, the maximum and minimum phase angles of a particular dimmer is detected during operation of the solid-state lighting load. Output power of the power Converter starts the operation of the solid-state lighting load, is adjusted automatically, based on the detected maximum and minimum phase angles of the dimmer,so the level of light output by the solid-state lighting load at maximum phase angle of the dimmer is a predetermined value of the upper edge, and the level of light output by the solid-state lighting load at minimum phase angle of the dimmer is a predetermined value lower edge.

Fig. 2 is a structural diagram depicting an adjustable lighting system includes a dimmer, electrical detection scheme with a phase angle dimmer, a power Converter and a solid-state lighting device, in accordance with the illustrative option implementation.

With reference to Fig. 2, the lighting system 200 includes a controller 204 illumination and circuit 205 straightening that provide (adjusted) rectified voltage Urect from the mains voltage 201. Mains voltage 201 can provide different nevirapine inputs mains voltage, such as WAH, WAH, WAH and WAH, in accordance with various embodiments. The controller 204 light is a terminating phase dimmer, for example, which provides the regulatory ability by cutting off the trailing edge (the dimmer of the trailing edge) or leading edge (dimmer leading edge) of the waveforms of the voltage signal from the mains voltage 201, in response to its vertical device a shift. For purposes of discussion, assume that the controller 204 light yavl�is the dimmer of the trailing edge.

In General, the absolute value of the rectified voltage Urect is proportional to the phase angle or the level of regulation that are configured by the controller 204 of the light, so that the phase angle corresponding to a lower setting of the dimmer, leads to a lower rectified voltage Urect. In the depicted example, it is assumed that the device a shift moves down to the lower right corner of the phase, reducing the amount of light output from the load 240 solid-state lighting, and moves up to increase the phase angle, increasing the amount of light output from the load 240 solid-state lighting. Therefore, the smallest regulation occurs when the device a shift is in the uppermost position (as shown in Fig. 2), and most regulation occurs when the device a shift is in the lowest position.

The illumination system 200 further includes circuitry 210 detecting a phase angle of the dimmer and the Converter 220 power. Circuit 210 detecting a phase angle of the dimmer is arranged to determine the phase angle (level of control) of the respective controller 204 of illumination based on the rectified voltage Urect, and dynamically set the operating point of the Converter 220 power based, in part, define�Lenno phase angle, with the help of control signal power. Converter 220 power receives the rectified voltage Urect from the circuit 205 rectification and control signal power, through a line 229 control, and outputs a corresponding DC voltage for supplying power to the load 240 solid-state lighting. The 220V power inverter converts the rectified voltage Urect and the DC voltage on the basis of at least the absolute value of the rectified voltage Urect and the values of the control signal, the power taken from the circuit 210 of the detection of the phase angle of the dimmer. The DC voltage derived by the Converter 220 power, thus, reflects the rectified voltage Urect and the phase angle of dimmer used by the controller 204 of illumination. In various embodiments, the Converter 220 operates according to the type of open loop or direct communication, as described in U.S. patent No. 7256554 in the name of Lys, which is incorporated herein by reference.

In various embodiments, the control signal power may be a signal of pulse width modulation (PWM), for example, which changes the high and low levels in accordance with the selected duty cycle. For example, the signal power control may have a high �oefficient fill (for example, 76 per cent), the working time of the controller 204 of illumination, and low fill factor (e.g., 12 percent), the corresponding low working time of the controller 204 of illumination. When the controller 204 of illumination is configured between the maximum and minimum phase angles, the circuit 210 of the detection of the phase angle of the dimmer further determines the duty cycle of power control, which specifically corresponds to detected the phase angle of the dimmer defined in accordance with the function configured for the maximum and minimum phase angles, as described below.

The controller 204 of the light may be one of various types of terminating phase dimmer compatible load 240 solid-state lighting, for example, available from various manufacturers. In General, each of the different types of dimmer provides various pre-defined maximum and minimum phase angles corresponding to the highest and the lowest setting of the dimmer. In other words, various types of dimming ballasts have different values for high working hours at the maximum setting of the dimmer for low working time at minimum settings swedenas�and, accordingly, discontinuous sinusoidal waves, where the "working time" is the time value when each discontinuous waveforms of the rectified input mains voltage is not equal to zero, as described above. Thus, each phase angle of the dimmer has a suitable working time and Vice-versa. In a conventional lighting system, different values of working time of various types of dimming ballasts are transferred to different levels of light and different ranges of regulating the light output of the load 240 solid-state lighting in response to what is otherwise the same settings of the dimmer.

However, in accordance with various embodiments of the implementation, the circuit 210 of the detection of the phase angle of the dimmer performs an algorithm to detect the maximum phase angle (corresponding to high working time) minimum and maximum phase angle (corresponding to low working time) the specific controller 204 light, and to regulate the output signal power so that the power output of the upper and lower edges, being delivered by the Converter 220 power to the load 240 solid-state lighting in response to the maximum and minimum of the phase angle regulator 204 light was the same, regardless of the type of boost�ora light. Accordingly, the output levels of the light load 240 solid-state lighting, likewise, are the same at the maximum and minimum of the phase angle regulator 204 light, regardless of the type of dimmer. Consequently, the upper and lower light output levels are set regardless of the type of dimmer and current maximum and minimum phase angles of the dimmer.

For example, when one type of dimmer has a longer working time than other type of dimmer, the circuit 210 of the detection of the phase angle of the dimmer will adjust the signal power control so that the output light load 240 solid-state lighting at the maximum setting with both knobs light is the same. Similarly, when one type of dimmer has a shorter working time than other type of dimmer, the circuit 210 of the detection of the phase angle of the dimmer will adjust the signal power control so that the output light load 240 solid-state lighting at the minimum setting both knobs light is the same.

Fig. 3 is a block diagram of the sequence of operations showing the process of controlling the amount of power delivered by the Converter modestina load solid-state lighting, in accordance with the illustrative option implementation. The process can be carried out, for example, hardware and software and/or software implemented the electrical circuit 210 detecting a phase angle of the dimmer shown in Fig. 2, or the microcontroller 615 in Fig. 6, described below.

In step S310 originally defined the relationship between the different angles of the phases (the working time of the dimmer) and the values of the signal power control to provide the desired upper and lower levels of light output load 240 solid-state lighting, when the controller 204 of illumination is configured to the maximum and minimum settings of the dimmer, respectively. Ratio is preserved for future access circuits 210 detecting a phase angle of the dimmer to the circuit 210 of the detection of the phase angle of the dimmer determined the correct function, which determines the output range of light load 240 solid-state lighting, based on the maximum and minimum phase angles of the dimmer and the associated values of the signal power control, and calculated values of control signal power, corresponding to the average of the phase angle of the dimmer on the basis of this function, as described below. For example, work�its the dimmer and the associated values for signal power control can be used to populate tables, the respective maximum and minimum settings of the dimmer, or can be stored in the database of relationships, although other means for storing the working time of the dimmer and the signal values of the power control can be included in the present document, without deviation from the scope of the present invention.

Initially, the desired upper and lower levels of light output (e.g., specified in lumens) are selected for output load 240 solid-state lighting at maximum and minimum settings of the dimmer, respectively. For example, the output level of light at 500 lumens can be selected as the upper level of output light, and the light output 25 lumens can be selected as the lower level of light output. For selected upper and lower light output level, the value of the reference signal power is determined for each of the plurality of possible upper values of working time (the maximum of the phase angle) corresponding to the various types of dimming ballasts, where each value of the signal power control adjusts the operating point of the Converter 220 power, to provide an output load 240 solid-state lighting 500 lumens in response to the upper value of working time. Similarly, for a selected minimum UB�nya output light, the value of the reference signal power is determined for each of the plurality of possible lower values of working time (minimum of the phase angle) corresponding to the various types of dimming ballasts, where each value of the signal power control adjusts the operating point of the Converter 220 power to output load 240 solid-state lighting 25 lumen in response to the lower value of the working time.

In accordance with various embodiments of the implementation, the values of signal power control can be defined by various means, without deviation from the scope of the present invention, a specific value can be a percentage of the maximum value of control signal power. Also, the signal power control may have a percent fill factor, as described below, which ranges from 100 percent to zero percent, with a certain value of the control signal power may be determined empirically, for example, at the stage of design, manufacture and/or installation. For example, the working hours and the control signal, the specific capacity of the dimmer may vary, to find the values of a signal power control at maximum and minimum of the phase angle of dimmer required to �downloading 240 solid-state lighting pissed desired lumen. Alternatively, the value of control signal power can be determined theoretically, that will be obvious to experts in the art, without deviation from the scope of the present invention.

In various embodiments, the working time of the dimmer and the corresponding values of the control signal with the capacity to generate a top-level output of light can fill the first correspondence table and the working time of the dimmer and the corresponding values of the signal power control to generate a lower level of output light can fill the second lookup table. For discussion purposes, table 1 provides an example of the first lookup table, which includes empirically derived associations between the upper values of the working time of the dimmer and the signal values of the power control, which lead to output 500 lumens load 240 solid-state lighting:

Table 1
Working time of the dimmerThe signal power controlThe output in lumens
7,0 MS90%50
7,2 MS87%500
7,4 MS82%500
7,6 MS80%500
7,8 MS78%500
8,0 MS76%500
8,2 MS74%500

As described above, the working time is the amount of time when each waveform discontinuous waveform of the rectified input mains voltage is not equal to zero (e.g., effectively corresponding to the time value when the electronic switch dimmer included), examples of which are depicted in the form of TonaTonbFig. 1A and 1B. With reference to the respective inputs in Table 1, for example, a dimmer that outputs a waveform signal having a working time of 7.0 MS at maximum setting, requires a relatively large signal power control (for example, having a fill factor of 90 percent) to the Converter 220 power provided to the output load 240 �verdolaga lighting 500 lumens. In comparison, the dimmer that outputs a waveform signal having a working time of 8.2 MS at maximum setting, requires a relatively small signal power control (for example, having a fill factor of 74%) to the Converter 220 power provided to the output load 240 solid-state lighting 500 lumens. Thus, for different values of the working time of the dimmer (different inputs of RMS value of voltage Converter 220 power) signal power control can be configured so that the output level of the light is a fixed top value is the maximum setting of the dimmer.

Similarly, for discussion purposes, table 2 provides an example of the second lookup table, which includes empirically derived associations between lower values of working time of the dimmer and the signal values of the power control, which lead to the output 25 lumens load 240 solid-state lighting:

/tr>

1,4 MS12%25
1.6 msec10%25
1.8 MS8%25
2.0 MS6%25
The 2.2 MS4%25

With reference to the corresponding entries in Table 2, for example, a dimmer that outputs a waveform signal having a working time 1.0 MS at the minimum setting, requires a relatively large signal power control (for example, having a fill factor of 16 percent) to the Converter 220 power provided to the output load 240 solid-state lighting 25 lumens. In comparison, the dimmer that outputs a waveform signal having a working time of 2.2 MS at the minimum setting, requires a relatively small signal power control (for example, having a coefficient of filled PTFE sheet thickness�Oia 4 percent), to Converter 220 power provided to the output load 240 solid-state lighting 25 lumens. Thus, for different values of the working time of the dimmer (different inputs of RMS value of voltage Converter 220 power) signal power control can be configured so that the output level of the light is a fixed lower value at the minimum setting of the dimmer.

The range of working time in Tables 1 and 2 may respectively contain known the difference upper operating time and lower the working time of the dimmer defined for a specific product (load 240 solid-state lighting). In various embodiments, Tables 1 and 2 can be stored in the schema 210 detecting a phase angle of the dimmer, so that for a particular upper or lower value of the working time of the dimmer. The value of the signal power control is determined and fed to the Converter 220 power for forming a predetermined upper and lower light output level. Also, although the illustrative Tables 1 and 2 show the working time of the dimmer to indicate the level of regulation set by the dimmer, it is clear that tables 1 and 2 can alternative shows� the phase angles of the dimmer to indicate the level of regulation, installed a dimmer, without deviation from the scope of the present invention.

With reference to Fig. 3, in step S320, the load 240 solid-state lighting connects to the controller 204 of illumination, together with the circuit 210 of the detection of the phase angle of the dimmer and the Converter 220 power, and works with different settings of the control knob 204 light. During this work, the maximum and minimum phase angles associated with the controllers 204 of the light is determined by the process depicted in step S330. Determination of maximum and minimum phase angles can be performed by dynamic detection of different phase angles of the dimmer and identify the largest and the smallest of the detected phase angles (for example, having the longest and the shortest working time of the dimmer, respectively) as the maximum and minimum phase angles.

Fig. 4 is a block diagram of the sequence of operations depicting the process of determining the maximum and minimum phase angles of the dimmer, in accordance with the illustrative option implementation. The process can be carried out, for example, in the form of software, hardware and/or software, in the form of sh�we 210 detecting a phase angle of the dimmer, shown in Fig. 2, or in the form of the microcontroller 615 in Fig. 6, described below.

With reference to Fig. 4, the initial maximum phase angle and initial minimum phase angle controller 204 of illumination configured in step S431, to begin the process. The initial maximum and minimum of the phase angle can be set to a predetermined nominal value. For example, the initial maximum and minimum of the phase angle can be set to the previously calculated average maximum phase angle and the average minimum phase angle sampling of the dimmer, which is comparable to the load 240 solid-state lighting. Alternatively, the initial maximum and minimum phase angles can be configured conventionally defined upper and lower values. Also, the initial maximum and minimum phase angles can be extracted from the device memory, where they were stored after the previous operation of the system 200 of lighting, to avoid double counting actual maximum and minimum phase angles during each operation of the load 240 solid-state lighting.

In step S432 is determined by the phase angle of the dimmer. For example, the phase angle may be detected in accordance with the algorithm shown in Fig. 8, described below, or learned from us�memory device (for example, storing information about phase angle in step S827 Fig. 8). In various embodiments, the phase angle of the dimmer is determined through the operation of the system 200 of lighting, so any changes in the phase angle of the dimmer, in response to changes in settings of the controller 204 of the light detected and handled.

In step S433, it is determined whether the detected phase angle smaller than the current minimum phase angle (for example, which is an initial minimum phase angle for at least the first cycle). When it is determined that the current detected phase angle is less than the minimum phase angle (step S433: Yes), the previous minimum phase angle is replaced by the current detected by the phase angle in step S434. When it is determined that the current detected phase angle is not less than the minimum phase angle (step S433: No), the process goes to step S435, where, it is determined whether the detected phase angle is greater than the current maximum phase angle (for example, which is the initial maximum phase angle for at least the first cycle).

When it is determined that the current detected phase angle is greater than the maximum phase angle (step S435: Yes), the previous maximum phase angle is replaced by the current detected by the phase angle in step S436. When�the determined, what's the current detected phase angle is not greater than the maximum phase angle (step S435: No), the process proceeds to step S437. Of course, in alternative embodiments, the determining whether the detected phase angle is greater than the current maximum phase angle, can be performed before or simultaneously with determining whether the detected phase angle smaller than the current minimum phase angle, without deviation from the scope of the present invention.

In step S437, the maximum and minimum phase angles of the dimmer, and the detected phase angle, back to the process shown in Fig. 3. In various embodiments, the maximum and minimum phase angles can be returned to the process shown in Fig. 3, only when changes were made to the minimum and/or maximum phase angles. Otherwise, the process shown in Fig. 3, continues to use the original or last specific maximum and minimum phase angles. The detected phase angle of the dimmer is returned so that you can determine the value of the signal power control to control an output of the inverter 220 power using a function defined from the maximum and minimum phase angles, as described below.

The process of determining the angle �basics of Fig. 4 continues, returning to step S432 where again is detected by the phase angle of the dimmer. Steps S433 on S437 are repeated during operation of the lighting system. Finally, the controller 204 of the light is adjusted to the most upper and most lower settings of the dimmer, and can identify the corresponding actual maximum and minimum phase angles. However, the scheme 210 detecting a phase angle of the dimmer continues to generate control signals power corresponding to the detected phase angles of the dimmer, as described below, so that the light switch can be performed at some level before, during or after the actual maximum and minimum phase angles.

Referring again to Fig. 3, in step S340 are identified by the value of control signal power corresponding to the maximum and minimum phase angles detected during the execution of step S330. This can be accomplished by using the relationship between phase angles and the values of the signal power control, defined in step S310. For example, the maximum and minimum phase angles have corresponding upper and lower working hours, which fills the previously stored first and second tables, as described above. For purposes of discussion, we can assume that, �of primer, upper working time was defined to be equal to 8 MS, and the lower the working time was defined as equal to 1.4 MS. With reference to Table 1, the value of the signal power control corresponding to the upper operating time 8 MS, equal to 76 percent, resulting in level of light output 500 lumens), and with reference to Table 2, the value of the signal power control corresponding to the upper operating time of 1.4 MS, equal to 12 percent (which will lead to the level of light output 25 lumens).

In step S350, the function representing the control range of the output light load 240 solid-state lighting between the upper and lower points corresponding to maximum and minimum settings of the power switch, is determined by the maximum and minimum phase angles (upper and lower values of working time) and the corresponding values of control signal power. In General, any of the plurality of functions relating the values of the signal power to the phase angle of the dimmer (or the values of working time), can be used in different embodiments, depending on the requirements-oriented application design and desirable implementations that will be obvious to specialists in this field of technology, provided that the function has no essential steps to avoid bol�large steps in the output light load 240 solid-state lighting.

Fig. 5A and 5B show examples of "smooth" or substantially continuous function relating the values of the power control (vertical axis) and the values of the working time of the dimmer (horizontal axis), where Fig. 5A depicts a linear function, and Fig. 5B depicts a non-linear function. For purposes of discussion, we can again assume that, for example, the upper working time and the corresponding signal power control were defined as equal to 8 MS and 76 percent, and lower working hours and the corresponding signal power control were defined as equal to 1.4 MS and 12 percent. With proper setting of the top point and bottom point of the function L on the basis of the dimmer, the upper and lower levels corresponding to the upper point and lower point L may be the same for different dimmer.

Although Fig. 5A and 5B depict the values of the working time of the dimmer in milliseconds, for the purpose of explanation, it is clear that each of the values of working time has an associated phase angle of the dimmer, as described above, the lower the value of working time (for example, 1,4 MS) is the corresponding minimum phase angle, and the upper value of working time (for example, 8 MS) has a corresponding maximum phase angle. Also, any function can be used to adjust the adjustable output range of light load 240 solid-state lighting, provided that it is smooth and has no large steps.

In step S360 in Fig. 3 the control signal power is calculated and generated based on the function of the output range of the light in step S350. Of course, if it is determined that the phase angle of the dimmer detected during the execution of step S330 (for example, in step S432), is the maximum angle phase or the minimum phase angle, then the corresponding value of the signal power control is already known (for example, from the first and second lookup tables). However, for the detected phase angles of the dimmer, between the maximum and minimum phase angles (intermediate phase angles of the dimmer), the value of the signal power control circuit is configured 210 detecting a phase angle of the dimmer based on the function, wherein the intermediate phase angles of the dimmer lead to the conclusion of the relevant intermediate levels of light load 240 solid-state lighting. In other words, in the examples shown in Fig. 5A and 5B, each of the intermediate phase angles of the dimmer can be graphically represented on a linear or non-linear curve, as a function of the detected phase angle of the dimmer (or working time of the dimmer).

Circuit 210 of the detection of the phase angle regulator�ora light sends a control signal to the power Converter 220 power. In response, sets the operating point of the Converter 220 power Converter 220 power delivers power to the load 240 solid-state lighting that corresponds to the RMS input voltage and a control signal power, so evenly adjustable level of light output load 240 solid-state lighting, regardless of the type of power switch.

Thus, in accordance with various embodiments of the implementation, the circuit 210 of the detection of the phase angle of the dimmer is arranged to identify the maximum and minimum of the phase angle regulator 204 light and to output control signals to the power that control the Converter 220 power, so the load 240 solid-state lighting displays predetermined upper level of light in response to the maximum phase angle and a predetermined lower level of light in response to the minimum phase angle. Circuit 210 detecting a phase angle of the dimmer also outputs control signals to the power corresponding to the detected intermediate phase angles between the maximum and minimum of the phase angle, based on the function of the output range of light which can be linear or nonlinear. Circuit 210 detecting a phase angle of the dimmer also outputs a power control,�reamer, through line 229 management, Converter 220V power, which dynamically adjusts the operating point of the Converter 220 power, as described above. Thus, power delivered to load 240 solid-state lighting, is determined by the RMS input voltage and the control signal power.

Fig. 6 is a schematic diagram depicting the control circuit of the lighting system, which includes the detection circuit with a phase angle of the dimmer, the power Converter and the load of solid-state lighting, in accordance with the illustrative option implementation. Common components in Fig. 6 similar components in Fig. 2, although it provided a more detailed description of certain illustrative components, in accordance with an illustrative configuration. Of course, other configurations can be implemented without deviation from the scope of the present invention.

With reference to Fig. 6, diagram 600 control includes circuitry 605 rectification and circuit 610 of the detection of the phase angle of the dimmer (dotted block). As described above in relation to scheme 205 rectification, circuit 605 rectification connected with the dimmer connected between the circuit 605 rectification and AC voltage (adjustable) nevirapine voltage specified by the inputs adjustment�already listed voltage and neutral. In the depicted configuration, the circuit 605 straightening includes four diodes D601-D604 connected between the node N2 of the rectified voltage and ground. Node N2 receives the rectified voltage rectified voltage Urect and connected to ground through a capacitor C filter input connected in parallel with the circuit 605 rectification.

Diagram 610 of the detection of the phase angle of the dimmer performs a process of detecting a phase angle based on the rectified voltage Urect. The phase angle corresponding to the level of regulation that is configured dimmer is detected on the basis of the degree of interruption phases present in the waveforms of the rectified voltage Urect. Diagram 610 of the detection of the phase angle of the dimmer determines whether the detected phase angle maximum or minimum phase angle in relation to a particular dimmer, and generates a control signal to power on the basis of the detected phase angle as described above. Converter 620 power manages the work load LED 640, which includes illustrative LED 641 and 642 connected in series, based on the rectified voltage Urect (RMS input voltage) and signal of power control provided by the circuit 610 discovery phase angle regulator �sidenote. This allows the circuit 610 of the detection of the phase angle of the dimmer to selectively adjust the power delivered from the inverter 620 power to the load 640 LEDs so that the output level of the light load 640 LED will be essentially uniform for the same settings of the dimmer (including the upper and lower settings) for many different types of dimming ballasts. In various embodiments, the transmitter 620 operates according to the type of open loop or direct communication, as described, for example, in U.S. patent No. 7256554 in the name of Lys, which is incorporated herein by reference.

In the depicted illustrative embodiment, the implementation, the circuit 610 of the detection of the phase angle of the dimmer includes a microcontroller 615, which uses waveforms of the signal of the rectified voltage Urect to determine the phase angle. The microcontroller 615 includes a digital input 618 connected between the first diode D611 and second diode D612. The first diode D611 has an anode connected to the digital input 618, and a cathode coupled to the source voltage Vcc, and a second diode D612 has the anode connected to ground and the cathode connected to the digital input 618. The microcontroller 615 also includes a digital output.

In various embodiments, the microcontroller 615 may be �of primer, PIC12F683 processor manufactured by Microchip Technology Inc and the transmitter 620 power can be L6562 manufactured by ST Microelectronics, although other types of microcontrollers, power converters or other processors and/or controllers may be included without departing from the scope of the present invention. For example, the functionality of the microcontroller 615 may be implemented by one or more processors and/or controllers connected to receive digital input between the first and second diodes and D611 D612, as described above, and which can be programmed via software or hardware-software means (e.g., stored in memory) to perform various functions described herein, or it may be carried out by a combination of dedicated hardware to perform some functions and a processor (e.g., one or more programmed microprocessors and associated circuits) to perform other functions. Examples of controller components that may be used in various embodiments include, but are not limited to, conventional microprocessors, microcontrollers, ASIC and FPGA, as described above.

Diagram 610 of the detection of the phase angle of the dimmer further includes various passive electronic�electronic components such as the first and second capacitors C and C, and resistance, specified illustrative first and second resistors R611 and R612. A first capacitor Is connected between the digital input 618 of the microcontroller 615 and the detection node N1. The second capacitor Is connected between the detection node N1 and ground. First and second resistors R611 and R612 are connected in series between the node N2 of the rectified voltage and the detection node N1. In the depicted embodiment of the first capacitor C can have, for example, a value of about 560 pF and the second capacitor C can have a value of about 10 pF. Also, the first resistor R611 can have, for example, a value of about 1 Mω, and a second resistor R612 may have a value of about 1 Mω. However, the respective values of the first and second capacitors C and C and first and second resistors R611 and R612 may vary to provide unique benefits for any particular situation or to meet the requirements based on the use of different design implementations that will be obvious to experts in this field of technology.

Rectified voltage Urect is connected alternating current with a digital input 618 of the microcontroller 615. The first resistor R611 and a second resistor R612 limit the current in the digital input 618. PR the rise of the waveform of the signal Vibram�enny voltage Urect, a first capacitor Is charged at increasing the front through the first and second resistors R611 and R612. The first diode D611 limits digital input 618 to a voltage above the source voltage Vcc at the falling of the diode, for example, when the first capacitor C is charging. A first capacitor C stays charged until the wave form of the signal is not zero. On dropping the front of the waveform signal of the rectified voltage Urect, a first capacitor Is discharged through the second capacitor C, and digital input 618 is limited to the second diode D612 to a voltage below the ground potential drop across the diode. When you use the dimmer of the trailing edge, falling edge waveform of the signal corresponds to the beginning of the discontinuous portion of the waveform. A first capacitor C remains discharged until the wave form of the signal is zero. Accordingly, the received digital input logic level digital input 618 closely follows the intermittent movement of the rectified voltage Urect, examples of which are shown in Fig. 7A-7C.

More specifically, Fig. 7A-7C depict examples of waveforms and corresponding digital pulses at the digital input 618, in accordance with the illustrative option implementation. The top waveform in each figure depict intermittent rectified voltage Urect, where the amount of stutter otra�AET level of regulation. For example, the waveform may represent part of the full peak of 170 In (or 340 In the EU) rectified sine wave, which appears at the output of the dimmer. The lower rectangular waveforms depict the corresponding digital pulses observed on the digital input 618 of the microcontroller 615. Namely, the length of each digital pulse corresponds to a discontinuous waveform and, thus, equal to the working time of the dimmer (e.g., the time value when the internal switch dimmer included). Taking digital pulses through the digital input 618, the microcontroller 615 is able to determine the level at which you configured dimmer.

Fig. 7A depicts an example of the waveform of the rectified voltage Urect and corresponding digital pulses when the dimmer is set to a maximum setting or upper working hours specified upper position of the sliding contact of the dimmer shown next to the waveforms. Fig. 7B depicts an example of the waveform of the rectified voltage Urect and corresponding digital pulses when the dimmer is configured on the intermediate setting is specified to the average position of the sliding contact of the dimmer shown next to the waveforms. Fig. 7C from�expresses an example of the waveform of the rectified voltage Urect and corresponding digital pulses, when the dimmer is configured to the minimum setting or lower working time indicated by the lower position of the sliding contact of the dimmer shown next to the waveforms.

Fig. 8 is a flowchart depicting a process of detecting the phase angle of the dimmer, in accordance with the illustrative option implementation. The process may be implemented by hardware and/or software executed by the microcontroller 615, shown in Fig. 6, or in General, a processor or controller, for example, circuit 210 detecting a phase angle of the dimmer shown in Fig. 2, for example.

In step S821 of Fig. 8 the rising edge of the digital pulse input signal (e.g., indicated the growing fronts of the lower waveforms in Fig. 7A-7C) is detected, for example, the initial charging of the first capacitor S. The sample on the digital input 618 of the microcontroller 615, for example, begins at step S822. In the depicted embodiment, the implementation, the signal is sampled into digital form for a predetermined time equal to a little less than half cycle of the mains. Each time the sampling signal in step S823 is determined whether the sample is a high level (e.g., a digital "1") or low level (e.g., a digital "0"). In the picture�nom variant of implementation, in step S823, a comparison is made to determine whether the sample is a digital "1". If the sample is equal to a digital "1" (step S823: Yes), the counter is incremented in step S824, and if the sample is not equal to a digital "1" (step S823: No), a small delay is introduced in step S825. The delay is introduced so that the number of clock cycles (e.g., the microcontroller 615) is the same regardless of whether the sample as equal to a digital "1" or digital "0".

In step S826 is determined whether the sampling of the entire half cycle of the mains. If the half cycle of the electrical network is not completed (step S826: No), the process returns to step S822 again to take a sample of the signal on the digital input 618. If the half cycle of the electrical network is completed (step S826: Yes), the taking of samples is stopped and the counter value is accumulated in step S824, is identified as the current phase angle in step S827, and the counter is reset to zero. The counter value may be stored in the memory device, examples of which are described above. The microcontroller 615 may then wait for the next rising front again to start taking samples.

For example, it can be assumed that the microcontroller 615 takes 255 samples for half cycle of the mains. When the phase angle of the dimmer is set u�means of sliding contact in the upper position of its range (e.g., as shown in Fig. 7A), the counter will get incremented to 255 in step S824 in Fig. 8. When the phase angle of the dimmer is mounted via a sliding contact in the lower position of its range (e.g., as shown in Fig. 7C), the counter will get incremented only up to 10 or 20 in step S824. When the phase angle of the dimmer is mounted via a sliding contact in the middle position of its range (e.g., as shown in Fig. 7B), the counter will get incremented to 128 in step S824. The counter value thus gives the microcontroller 615 accurate indication of the level at which the controller is configured light or the phase angle of the dimmer. In various embodiments, the phase angle can be calculated, for example, the microcontroller 615 with the predetermined function of the counter value, where the function may vary to provide unique benefits for any particular situation or to meet focused on application design requirements of various implementations that will be obvious to experts in this field of technology.

Accordingly, as described above, the upper and lower working hours specific device switching can be determined electronically using a minimum of passive components and structures qi�digital input of the microcontroller (or other processor or electric processing circuit), and the upper and lower working hours specific device switching can be used to dynamically configure the output levels of the light load solid-state lighting so that the light levels were substantially uniform (specifically, the top and the bottom of the settings of the dimmer) for many different types of dimming ballasts. In a variant implementation, the definition of the setting of the dimmer is performed via the associated AC schematic structure of a digital input with a diode limiting the microcontroller and the algorithm (implemented, for example, hardware, software and/or hardware) that runs for binary determine the presence of a dimmer as described above with reference to Fig. 6-8.

In other words, in accordance with various embodiments of the implementation, the upper and lower points function light output range is determined on the fly by first finding the maximum and minimum phase angles of the dimmer. Then the corresponding values of the signal power control are identified, for example, be found in the table are retrieved from a relational database or calculated, using the maximum and minimum of the phase angle regulator�and light to set the desired upper and lower levels of light output by the solid-state lighting load, regardless of actual control range of the dimmer. The function of the range of input light can be continuous, substantially continuous function, for example, providing increasing increments the value of control signal power corresponding to the phase angle of the dimmer between the upper and lower points.

Electric circuit to detect the phase angle of the dimmer and the associated algorithm can be used in various situations where it is desirable that different dimmers having different upper and lower settings of the dimmer, led to the same adjustment ranges of illumination when they are used with similar lighting products. In various embodiments, a circuit for detecting a phase angle of the dimmer and the associated algorithm can also be used in situations where additionally, it is desirable to know the exact phase angle of the dimmer to the interruption phase. For example, electronic transformers, which operate as a load for the dimmer to the interruption phase, can use this scheme and method for determining the phase angle of the controller osveshennosti�. Provided that the phase angle of the dimmer is known, the control range of illumination and dimmer compatibility illumination with respect to the load solid-state lighting (e.g., LED) can be improved. Examples of such improvements include the management of color temperature of the lamp with the settings of the dimmer, the determination of the minimum load at which the dimmer can operate in place of, definition of, when the power switch is working on site with interruptions, changing the ranges of the output light, and the creation of individually controllable light curve according to the position of the sliding contact.

In General, various options for implementation may be used in situations where adjustable electronic ballast load connected to the dimmer, and it is desirable to have the same levels of light output at maximum and minimum settings of the dimmer, regardless of the type of dimmer. In various embodiments, the functionality of the circuit 210 of the detection of the phase angle of the dimmer and/or the microcontroller 615, for example, can be implemented by one or more processing circuit that consists of any combination of hardware, software and hardware or software.�countries and may include its own memory (e.g., nonvolatile memory) for storing executable software/executable code of the software and hardware that allows you to perform various functions. For example, such functionality may be implemented using ASIC, FPGA and the like.

The setting range of the output light, the same for the different dimming ballasts that can be used for any of the regulated power Converter with load solid-state lighting (e.g., LED), where it is desirable to have the same optimum performance in the range of light output when using different dimmer with interruption phases with different minimum and maximum settings of the dimmer. The detection circuit of the phase angle of the dimmer, in accordance with various embodiments of the implementation, can be implemented in various products EssentialWhiteTM and/or eW manufactured by Philips Color Kinetics, including eW Blast PowerControl, eW Burst PowerCore, eW Core MX PowerCore, eW PAR 38 and the like. Additionally, it can be used as a component of "intelligent" improvements for various products to make them compatible with the dimmer.
