Optical control lamp control circuit and brightness threshold regulation and control method

Abstract

The invention relates to an optical control lamp control circuit and a brightness threshold regulation and control method. The optical control lamp control circuit comprises a main control chip, a photosensitive detection module, a brightness threshold adjustment module, a lighting control module and a power supply module, wherein the main control chip is internally preset with a reference brightness threshold; the photosensitive detection module is used for receiving external light to form light intensity signals; the brightness threshold adjustment module is connected with the main control chip for setting and adjusting the reference brightness threshold according to the size of the resistance value; and the lighting control module is connected with the main control chip for controllinga lighting lamp to be off when the light intensity signals exceed the reference brightness threshold and controlling the lighting lamp to be on when the light intensity signals are smaller than the reference brightness threshold. As the reference brightness threshold is set through adjusting the size of the resistance value of the brightness threshold adjustment module and the size of the brightness threshold adjustment module can be adaptively adjusted according to the sensitivity of the photosensitive detection module, the control accuracy is thus improved, external adding of a sensing switch is not needed, the wiring difficulty is reduced, and the maintenance is more convenient.
