FIELD: electricity.SUBSTANCE: invention related to the field of electric engineering. device (1) for connection of a source (2) of power supply to a light diode lamp (3) comprises the first part for reception of the first signal of current and the first signal of voltage from the source (2) of power supply and the second part for supply of the second signal of voltage and the second signal of current to the lamp (3). The first part comprises a detecting part (11) for detection of first amplitude reduction in at least one of the first signals, for instance, in the first signal of voltage. And the second part comprises an input part (12) to input, in response to the detection result, reduction of the second amplitude, at least into one of the second signals, for instance, into the second signal of current. As a result, the first part detects the first condition of light force reduction caused by the source (2) of power supply, and the second part inputs the second condition of light force reduction in response to the fact that the first part detected the first condition of light force reduction.EFFECT: device (1) is capable of independent reduction of light force, to preserve stability of a power supply network.13 cl, 5 dwg |
