LAYOUT OF LIGHT-EMITTING DIODE CIRCUIT WITH IMPROVED TWINKLING PERFORMANCE Russian patent published in 2014 - IPC H05B33/08 

Abstract RU 2511714 C2

FIELD: electricity.

SUBSTANCE: invention relates to the field of lighting equipment. Layout (1) of the circuit for light-emitting device includes the first branch (2) of the circuit for alternating voltage receipt which contains the first circuit (3) of light-emitting diodes (LEDs) connected in-series with the first phase-shifting element (4), the second branch (12) of the circuit connected in parallel to the first branch of the circuit, at that the second branch of the circuit contains the second LED circuit (13) connected in-series with the second phase-shifting element (14) in revere order in comparison with LED circuit and phase-shifting element in the first branch of the circuit, and the third branch (22) of the circuit containing the third LED scheme (23) connected in-between the first and second branches. With such circuit design current can be phase-shifted through the first and second LEDs in comparison with current passing through the third LED circuit so that the first and second LED circuits emit light within one period of time while the third LED circuit emits light within second period of time.

EFFECT: reducing blinking effect.
