POWER SUPPLY FOR LIGHT-EMITTING DIODES Russian patent published in 2010 - IPC H05B33/02 

FIELD: physics.

SUBSTANCE: proposed power supply includes a power factor corrector (PFC), a temperature sensor, a photosensor for automatic switching on of light and a multiplier for regulating light intensity. A supply voltage sensor enables switching off the power supply when the input voltage of the power circuit overshoots the normal value. The included n circuit breakers, n stabilisers and n human presence sensors enable switch off of light from any of the n light-emitting diodes, protection of the current circuit of the light-emitting diodes when any of the light-emitting diodes fails and automatic switch off of light in the absence of people.

EFFECT: broader functionalities.
