Embodiment
[0021] Such as figure 1 As shown, the stabilised source corridor energy-saving lighting system of the present invention is mainly composed of a central controller, a power input protection circuit connected to the central controller, a lighting drive circuit and an analog-to-digital conversion chip, respectively connected to the analog-to-digital conversion chip It consists of an infrared sensor, a light sensor, and an illuminating lamp connected to an illuminating drive circuit.
[0022] Wherein, the central controller is used as the control center of the present invention, and its preferred STC90C52AD single-chip microcomputer is realized. The infrared sensor can detect whether there are pedestrians passing in the corridor, and the LH1958 infrared sensor is preferred. The light sensor can detect the light brightness in the corridor, and it is preferably realized by the EM30713 light sensor produced by Shenzhen Shuoshi Technology Co., Ltd. The module conversion chip is used...
