Additional objectives of the invention is the provision of a device, method, computer program product and media.

In accordance with the first aspect of the invention the device is designed to connect the power source to the lamp, and the lamp contains one or more light emitting diodes, where the device includes:

- the first part for receiving the first voltage signal and the first signal t is ka source (2) power the first part contains the detecting portion (11) for detecting the lowering of the first amplitude, at least one of the first signals indicating the lowering of the output power of the power source, and

- the second part for supplying the second voltage signal and the second signal current to the lamp (3), and the second part contains misleading part (12) for the introduction of a lower second amplitude in response to the detection, at least one of the second signals, for reducing power supplied to the lamp, in order to stabilize the power source.

The first part, such as the first (part) scheme, receives the first voltage signal and the first signal current from the power source. This first part contains the detecting part for detecting the lowering of the first amplitude, at least one of these first signals. The second part, such as a second (part) scheme, delivers the second voltage signal and the second signal current to the lamp. This second part contains the introducing part for introducing, in response to the detection, reduction of the second amplitude, at least one of the second signals. As a result, the first part detects the first state of the control light power caused by the power source, and the second part introduces the second state regulation of light intensity in response to the first cha is th detektirovaniya the first state to control the power of light.

The second state of the control light power is more able to control the power of light, which is entered in response to the first state regulation of the forces of light and which gives the device the ability to self-regulate the forces of light.

Using a lamp containing one or more light emitting diodes, such as organic light emitting diodes, inorganic light emitting diodes and/or laser light-emitting diodes, this lamp, in comparison with other types of lamps, will be less sensitive to low amplitude. This lamp can be easier stewed without change of service life and maintenance. He immediately returns to normal operation, if the rated power is supplied again. Additionally it should be noted that the light output of such lamps increases significantly for the current below the nominal value. For example, some products of the light-emitting diodes the best characteristics are measured at one-fourth of the rated capacity. This means in practice that the reduction in the input power leads to a smaller decrease in luminous flux.

Therefore, it is preferable that in the case where the power source supplies power at a lower level, the combination of the device and the lamp would require power on the advanced low level from the power source to maintain grid stability.

In this case, different lower first amplitude lead to the second depressions amplitude having a different second duration.

In accordance with the embodiment of the invention the device is characterized by the fact that the lowering of the first amplitude has a first slope, and the first inclination may be determined by the detecting part.

Then, for example, the phase of the sine wave can be recorded and can be compared to the cycle to enter the auto-tuning.

DESCRIPTION of the PREFERRED embodimentsINVENTIONS

Figure 1 shows possible implementation of the device 1 for connecting the source 2 power supply and lamp 3. Lamp 3 contains one or more light emitting diodes. In the case when the lamp 3 contains two or more light-emitting diodes, any two or more light-emitting diodes can be connected, at least partially, the serial connection and/or at least partially, in parallel connection. The device 1 includes a first part for receiving the first voltage signal and the first signal current from the source 2 power, such as electricity. This first part contains the detecting section 11 for detecting the lowering of the first amplitude, at least one of the first signals. The device 1 further comprises a second part for supplying the second voltage signal and the second signal current to the lamp 3. This second part contains misleading part 12 for introducing, in response to the detection, reduction of the second amplitude, at least one of the second signals.

Usually lowering the amplitudes are low amplitude in real time, and (introduction) start lowering the second amplitude is preferably introduced in a relatively short period of time (detection) start lowering the first amplitude. Alternatively, one or more depressions amplitude can be averaged low amplitude. Preferably, the lowering of the first amplitude was decreasing amplitude of the first signal voltage, and lowering the second amplitude was decreasing amplitude of the second current signal. Additionally, it is desirable to decrease the first amplitude would lead to the fact that the power output of the source 2 power down, and three times lower amplitude would lead to the fact that this power output is reduced additionally.

The first part may further comprise a rectifier 13, for example, contains one diode or containing the four diodes in a bridge circuit for rectifying signals of voltage and current from the mains in the first signal voltage and current. Lane is the first part may further comprise a first serial circuit of the resistors 14 and 15 and the second serial circuit of the diode 16 and capacitor 17. The outputs of the rectifier 13 is connected to the inputs of the first and second sequential circuits. The output of the first sequential circuit (the interconnection between the resistors 14 and 15) is connected with the input of the detecting part 11. It is possible that additional capacitor 18 may be placed in parallel with the resistor 15.

Introducing part 12 of the second part comprises a control input connected to the output of the detecting part 11 includes inputs connected to the output of the second sequential circuit (interconnect between the diode 16 and capacitor 17 and the output of the rectifier and provides outputs which should be connected to the lamp 3.

Figure 2 shows a variant implementation of the detecting portion 11 of the device 1. The detecting part 11 may, for example, include comparing part 41 for comparing the amplitude of at least one of the first signals with a threshold value and may, for example, include generating part 42 for generating, in response to the comparison result, the control signal supplied to the introducing portion 12 through the interconnect 43.

Figure 3 shows a variant implementation of the introducing portion 12 of the device 1. Introducing part 12 may, for example, contain a schema 44, 45, containing the layout 44 connected to the interconnect 43 and transistor 45 to control the amplitude, in response to the control signal, at least one of : the x signals.

Parts 41 and 42 and arrangement 44 can each be based on analog technology, or digital or a combination of both of them. One or more analog-to-digital converters and one or more digital to analog converters may be present in the composition of the parts 41 and 42 and the link 44 or can be added to one or more inputs and one or more outputs of these parts 41 and 42 and the link 44. Instead of the transistor 45 can be used other semiconductors, and more complex schemes. Therefore, an implementation option with a more complex scheme, which introduces a reduction of the second amplitude of the second signal via, for example, pulse width modulated with a duty cycle or any other type of modulation scheme, which leads to a change in amplitude, depending on the measured reduction of the first amplitude of the first signal, is also included. This modulation scheme or template switching for amplitude may, for example, contain a density modulation pulse frequency modulation, phase modulation angle modulation phase shift, etc.

Resistors 14 and 15 form a voltage divider, so that the peak voltage can be compared with a threshold. Alternative this voltage divider may be omitted, or may be built into the detecting part 11, or may be located is ogen after the condenser 17, or may be replaced by another arrangement, such as a transformer. Additionally, alternative, instead of the peak voltage can be compared with another threshold voltage, such as, for example, the average voltage. The diode 16 has the function of interchanges; alternative can be used decoupling layout. The detecting part 11 can alternatively perform calculations for the purposes of detection in this case is the result of a calculation or shows the result of the detection. Introducing part 12 contains a diagram of the excitation light-emitting diodes. The detecting part 11 is fed through rectifier 13, but can alternatively be powered from a battery or other source. Source 2 power supply may alternatively be a power supply such as an AC to DC current fed from the power supply or Converter DC to DC current fed from the battery or another battery or a solar panel system, etc.

Figure 4 shows a first diagram (lower) outlet figure 5 shows a second diagram (low) power and signal monitor both voltage over time. The signal monitor, for example, is a signal that must be submitted to the detecting part 11. For example, the normal signal monitor may be 100 Hz, after straightening up, will bring the flax, 20th Century When it falls below 19.2, the system detects low grid and controls the lamp 3 to decrease the brightness.

Can be applied several General ways, such as instant demotion to a fixed level of regulation of the forces of light, or a smooth decrease due to reduction in mains voltage. To eliminate the flashing brightness at low networks, regulation of light intensity should be gradually increased, if the voltage becomes higher. For example, regulation of light intensity should be increased by a pre-set percentage over the period of the grid.

To implement complex control scheme, it would be easier to track the voltage through analog-to-digital Converter of the digital controller. Many new fixtures can be used by the microcontroller in any way to control the power of light, color management and remote control decoding. In these lamps the microcontroller has been used successfully for the analysis of waveforms outlet and run circuit for controlling power of light, as briefly described above.

An improved version of the implementation could even react to the different degree of the voltage drop in the mains with different dimensions. For example, in the case of very deep drop, power consumption can is be completely turned off for a short period, to enable the grid easier to return to normal. Instead of a fixed threshold, it would be more convenient to have a means of averaging, which constantly measures the average voltage and dynamically adjusts the threshold relative to the average measured voltage.

If you use a digital controller, it would be possible to save waveforms for a couple of periods outlet and compare the current value synchronously with earlier measurements. Thus, it is possible to immediately recognize deviations. To this end, the microcontroller needs some accumulating capacitor for storing the old values. An additional capacitor 18 may be set to a smaller value, so it can detect deviations faster. Thus, the lamp 3 can even reduce its capacity before the voltage drops below a certain limit.

Temporary slopes for changes in the values of the control light power (possibly different for top and bottom) allow you to make final changes in the brightness of the lamp so gently as possible, and so long as the sign does not require immediate (and visible) response.

These types of devices, such as, for example, SSL electric choke starter can become popular utilities for the special the CSOs pricing power in the future, because light-emitting diode lamps can respond relatively quickly to changes in electrical power, decentralized, manageable way. Additional impact in the controller of the lamp may be very small.

An additional application is possible when performing the control light power light-emitting diode lamp through a centralized reduce the mains voltage. This method of control is known in street lighting, but does not work with existing electronic excitation schemes because these schemes excitation counteract increasing its output current through the control mechanism to its internal current.

In an additional embodiment, can be used a separate circuit, which measures in a Central location (for example, the place where the story of a light panel is located so that it skips the remote commands to the lamps to reduce power). This can also be done in such way that different lamps have different decrease of luminous flux depending on the distribution of lamps and minimum functional length of the stream. In an additional embodiment, the Central station controls the lamps to control the forces of light reduced by the I voltage directly or through an intermediate controller power for example, on each floor.

In the end, the device 1 for connecting the source 2 power to the light emitting lamp 3 contains the first part for receiving the first current signal and the first voltage signal from the source 2 power supply and the second part for supplying a second current signal and the second signal voltage to the lamp 3. The first part contains the detecting section 11 for detecting the lowering of the first amplitude, at least one of the first signals, for example in the first voltage signal, and the second part contains misleading part 12 for introducing, in response to the detection, reduction of the second amplitude, at least one of the second signals, the second signal current. As a result, the first part detects the first state regulation of light intensity caused by the source 2 power, and the second part introduces the second state regulation of light intensity in response to the first part, having detektirovanie the first state of the control light power, and the device 1 has the properties of self-regulating forces of the light to maintain the stability of the grid.

While the invention has been illustrated and described in detail in the drawings and in the preceding description, such illustration and description should be considered as an illustration or example, and not limitation, the invention is not limited to the network expanded options for implementation. For example, it is possible that the device worked by a variant implementation, in which different parts of the various disclosed embodiments are combined in the new version of the implementation.

The computer program may be stored/distributed on a suitable medium such as an optical recording medium or semiconductor medium supplied together with or as part of other hardware, but may also be distributed in other forms, such as the Internet or other wired or wireless telecommunication systems. Any designation of any link does not must in order to meet the threshold limit.

SUBSTANCE: invention relates to electrical engineering, particularly systems for controlling lamps by encoding an AC power signal. AC line voltage may be encoded with control information, such as dimming information derived from an output signal of a conventional dimmer, so as to provide an encoded AC power signal. One or more lighting units, including LED-based lighting units, may be both provided with operating power and controlled (e.g., dimmed) based on the encoded power signal. In one implementation, information may be encoded on the AC line voltage by inverting some half cycles of the AC line voltage to generate an encoded AC power signal, with the ratio of positive half-cycles to negative half-cycles representing the encoded information. In other aspects, the encoded information may relate to one or more parameters of the light generated by the LED-based lighting unit(s) (e.g., intensity, colour, colour temperature, etc.).
