PIR Lighting control system comprising PIR sensor array illumination sensor and dimming controller

摘要

The present invention relates to a lighting control system and, more specifically, to a lighting control system including a PIR sensor array, an illumination sensor, and a dimming controller. The lighting control system of the present invention comprises: non-amplifying PIR sensor modules consisting of one PIR sensor and one Fresnel lens, without an amplification circuit; one amplification circuit part for receiving a current signal outputted from a plurality of PIR sensor modules, and amplifying and outputting the inputted current signal; a microcomputer for outputting a control signal using the amplification circuit part signal and an illumination signal; and an LED lighting with illumination controlled by the microcomputer. The non-amplifying PIR sensor modules are arranged for the sensing areas to overlap each other.
