Embodiment
[0021] Such as figure 1 As shown, the signal amplified corridor energy-saving lighting system of the present invention is mainly composed of a central controller, a power supply connected to the central controller, a lighting drive circuit, and a two-stage fidelity amplifying circuit, which are connected with a two-stage fidelity amplifying circuit It consists of an analog-to-digital conversion chip, an infrared sensor and a light sensor connected to the analog-to-digital conversion chip, and a lighting lamp connected to the lighting driving 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 S...
