WIRING DIAGRAM OF LED LIGHT DEVICE TO AC SYSTEM Russian patent published in 2017 - IPC H05B37/02 

FIELD: lighting.

SUBSTANCE: invention relates to electronic devices for the inclusion of light devices into the AC system in which light-emitting semiconducting diode (LED) groups are used as light sources. Certain LED devices of this kind have a high coefficient of the light flux pulsation, which has a negative effect on overall and visual performance. The essence of the invention lies in the fact that the wiring diagram of the LED light device to the AC system containing n (n=2, 3, …) of the series-connected LEDs, a diode rectifier which positive output is connected to the anode of the first LED, the first resistor, one output connected to the negative output terminal of the diode rectifier, n controllable normally open switches and n-1 monitoring switches are introduced, a resistor voltage divider of two series-connected resistors, connected in parallel with the output of the diode rectifier, and a controller with a processor and two ADCs.

EFFECT: circuit has a smaller value of the ripple factor and does not affect the overall and visual performance.
