LED LIGHT SOURCE AND LAMP COMPRISING LED LIGHT SOURCE Russian patent published in 2014 - IPC H05B33/08 H05B37/02 

FIELD: electricity.

SUBSTANCE: invention relates to lighting engineering. A LED light source comprises: the first rectifier having the first and the second input terminals to connect to the alternating voltage source and the first and the second output terminals connected by the first LED circuit, the second rectifier having the first and the second input terminals and output terminals; the first input terminal of the second rectifier is connected to the first input terminal of the first rectifier and the second input terminal of the second rectifier is connected to the second input terminal of the first rectifier, the output terminals are connected by the second LED circuit, it also comprises a unit to create phase shift between the voltages which are present at the output terminals of the first rectifier and the output terminals of the second rectifier respectively in the course of operation. The LED circuits are excited by the circuit that can be powered from electricity supply network.

EFFECT: possibility to suppress stroboscopic effects.
