LIGHTING DEVICE, SUITABLE FOR MULTIPLE VOLTAGE SOURCES Russian patent published in 2018 - IPC H05B33/08 

FIELD: electricity.

SUBSTANCE: invention relates to a lighting device for a plurality of voltage sources. Invention further relates to a circuit and apparatus for use in such a lighting device. Result is achieved due to that the lighting device suitable for a plurality of voltage sources comprises first circuit (1) with diode circuits coupled to input terminals (2, 3) for receiving first voltage signals from first circuits such as voltage-to-voltage converters. Diode circuits comprise diodes (11-14) for rectifying the first voltage signals and are coupled to output terminals (4, 5) for supplying second voltage signals. First capacitors (15) are coupled to output terminals (4, 5) for buffering the second voltage signals and for offering buffered second voltage signals to second circuits such as voltage-to-current-converts for feeding light circuits comprising one or more light emitting diodes. Second capacitors coupled in parallel to one of diodes (11-14) provide a charge-pump effect to improve performances of the first and second circuits and the light circuits.

EFFECT: technical result is providing a lighting device suitable for use in combination with a plurality of voltage sources, in particular a plurality of transformers.
