LED LAMP DRIVER AND METHOD Russian patent published in 2014 - IPC H05B33/08 

FIELD: electricity.

SUBSTANCE: invention is related to illumination systems based on light-emitting diodes (LED). LED lamp driver receives direct-current power of low voltage, at that the LED driver includes the following components: push-pull transformer circuit connected to receive direct-current power of low voltage and to generate alternating-current energy by the transformer, at that the push-pull transformer circuit contains switches reacting to control signals; self-resonant control circuit connected to the push-pull transformer circuit in order to generate control signals; current controller coupled to receive alternating-current energy of the transformer and to generate alternating-current controlled energy; AC/DC converter coupled to receive alternating-current controlled energy and to generate direct-current energy of high voltage.

EFFECT: provision of LED overheating protection and efficiency increase.
