In this first configuration scheme 3 LEDs contains, for example, counter the LEDs 31 and 32.

Do not exclude additional LEDs and other associations LEDs. Alternatively, an additional resistor 91 may form part of the circuit 3 LEDs. Figure 1 depicts the dimmer 2 with phase control in the form of a block, which interrupts the two wires. In the minimum case, the dimmer phase control may interrupt only one of the wires without interrupting the other.

This input is, for example, the interconnect between the first resistor element 51 and 52 of the reference voltage. One should not exclude the active elements other than transistors 54 and 63. When using a microprocessor circuit 7 input can be connected to the output of the circuit 5 current limit. This output is, for example, the interconnect between the second resistor 53 and the transistor 54.

Elements 51-54 form a current source which, when exceeding a threshold level voltage on the output pins of the rectifier 8 is deactivated elements 61-63.

The management scheme, such as a microprocessor circuit 7 enables more intelligent detection and management by analyzing the power divider (voltage across the resistor 53 and the shape of the applied input voltage. Using the parameters of voltage microprocessor circuit 7 can distinguish front front and rear front and to detect the presence of a dimmer. If the dimmer is not present, the circuit 1 voltage divider can be switched off, thereby eliminating the additional the first power consumption. Dimmers front, which is typically used triac require maximum current of the voltage divider. In fact, the supplied current can be measured across the resistor 53 during the time interval when the voltage is lowest. Then microprocessor circuit 7 can set the value of the limiting current is slightly above this level and, thereby, to minimize the power consumption of the voltage divider to a specific dimmer.

Figure 3 shows the dimmer 2 with the phase control circuit 1 voltage divider and scheme 3 LEDs in the second configuration. Two of the input contact of the dimmer 2 with phase control must be connected with a not shown (AC) power source and two output contacts dimmer 2 with phase control are connected with two input contacts schematic 1 voltage divider. Diagram 1 voltage divider includes a rectifier 8, having two input contact, which form two input contact circuit 1 voltage divider, and having two output contacts connected to two input pins of the active circuit 4.

Figure 5 current limiting contains a parallel connection of the first and second serial connections. First serial connection includes a first resistor element 51 and 52 of the reference voltage, such as a Zener diode, and a second serial connection includes a second resistor 53 and an active element such as transistor 54.

Control electrode of the additional transistor 63 is connected to the interconnect between the third and fourth resistors 61 and 62, and the main electrode of the additional transistor 63 is connected to the input circuit 5 current limit.

In the minimum case, the dimmer circuit may interrupt only one of the wires without interrupting the other. In a more advanced case, the control scheme of the forces of light can break one of the wires and use information from another or may interrupt the two wires etc.

On Fig shows a device 10 that has the dimmer 2 with the phase control circuit 1 voltage divider and scheme 3 LEDs. In the minimum case, the device 10 includes a circuit 1 voltage divider; in a more advanced case can also be dimmer 2 with phase control and/or scheme 3 LEDs and/or stabilizing the load for the dimmer with phase control. The above scheme 1 voltage divider may form part of such a stabilizing load.

The control circuit 9 can optionally be connected to ground, and the alternative can be implemented through a scheme 6 detection voltage or by a control circuit such as a microprocessor circuit 7.

Preferably by providing an active circuit 4 circuit detection dimmer, such as a detector for detecting one or more phase interrupt, in response to the result of detection, scheme 1 voltage divider can be Akti is arowana or deactivated, for example, the time interval in which, for example, once per interval of time or soon after the end of the time interval may be performed by another detection. Such a detector can be implemented by a control circuit such as a microprocessor circuit 7.

The present invention eliminates the drawback consisting in the fact that the circuit of the LEDs when connected to a standard dimmer may experience flickering. In particular, the nominal power schemes LEDs is significantly lower than the minimum power required for the correct operation of the dimmer, and even should be further reduced. Most dimmers always requires some outline of the reverse current, but, for example, LEDs AC are conductive only when the voltage is above a certain threshold. Below this threshold voltage, no current through the load flows. The dimmers on the basis of the triac requires a minimum current to triac remained conductive and, for example, modified small led lights consume only the current, which is already below this level. Many dimmers when turned off still provide at the output of visible radiation and demonstrate increased power consumption in the standby mode.

To animalname advantages of the invention can be its own built-in power supply (no auxiliary voltage sources, diagram of the voltage divider starts to operate at close to zero input voltage, the circuit of the voltage divider remains active when switched off the lamp), self-limiting peak current (no emissions in the current network, internal self-protection and minimum power consumption circuitry of the voltage divider compared to the resistive solution), automatic deactivation at high voltage (no increase in peak current network, improved total harmonic distortion of the network and the minimum energy consumption) and advanced adaptive control circuit of the voltage divider (regulation peak current in accordance with the requirements in more low power loss and high compatibility dimmer, and activation schematic of the voltage divider only in those cases when it is really necessary, in the absence of a power loss, if the dimmer is not connected/not used, otherwise there is a 50%reduction of power losses).

The dimmers on the basis of the triac requires an increased current of the voltage divider due to the characteristics of the triac. By adding a means of detecting the level of current of the current source can be adjusted depending on the detected requirements. Another interesting feature is the fact depending on the type of dimmer to activate the schema of the voltage divider is needed only the first or last half of each politicla. Thus, the detection means may deactivate the current source of approximately half the time when using the dimmer. If one dimmer connects more than one light source, the current requirement of the voltage divider on the light source are reduced. The detection means may be capable of detecting this and reduce the setting of the current accordingly to reduce power losses. Finally, if the dimmer is not used, power consumption can be minimized due to the complete deactivation of the circuit of the voltage divider.

Summarizing, we can say that the diagram 1 voltage divider for associations dimmer 2 with phase control and diagrams 3 LEDs contain active circuit 4 to increase the number of options. Active scheme 4 can contain scheme 5 current limit to limit the current flowing through the circuit 1 voltage divider. Active scheme 4 can contain schema 6 detection voltage for activation or deactivation scheme 5 current limit in response to the result of detection, and may include a driver circuit such as a microprocessor circuit 7 to the control circuit 5 current limiting and may include a control circuit 9 for the use of the information obtained from the current flowing through the circuits of the 3 LEDs, for schema management 5 current limit to control at least part of the schema 3 LEDs, which contains the counter LEDs 31-32 or serial and/or parallel LEDs 33-36.

SUBSTANCE: method and device are proposed for power-saving control of street lighting, which consist in autonomous adaptive street lamps during the day depending on duration of a light day calculated for every day of the calendar year for this geographic area, and also road traffic intensity. The technical objective of the proposed invention is aimed at increasing energy efficiency and safety of street lighting control. The method provides for functioning of the lighting system in a power-saving mode (mode of lamps dimming), which is subdivided into the basic and optimal power-saving mode. The basic power-saving mode is the mode, when street lamps are dimmed for the knowingly permissible interval of time. The optimal power-saving mode is the mode, when duration of the power-saving mode is maximum for the current date. In the case when values of time for switching on and off are not defined for both optimal and basic power-saving mode, the power-saving mode in the subsequent cycle of operation of street lamps is not switched on. The device comprises a source of light, a power supply unit, a unit of adaptive dimming, a sensor of road traffic intensity (option), and makes it possible to carry out autonomous adaptive dimming of street lamps during the day.
