Abstract

The invention discloses an intelligent illuminating system based on PWM technology. The intelligent illuminating system includes a plurality of illumination control regions each of which includes at least one entrance / exit, each illumination control region is provided with an infrared detection module, a distance detection module, an AD conversion circuit, an optical signal acquisition circuit, a single-chip microcomputer, a brightness level display circuit and an illumination module, and the infrared detection module and the distance detection module are installed at the entrance / exit of the illumination control region. The intelligent illuminating system based on PWM technology solves the problem that an existing shopping mall adopts unified illumination, power consumption is too large, and electric energy is wasted.

Description

technical field [0001] The invention relates to the field of lighting control, in particular to an intelligent lighting system based on PWM technology. Background technique [0002] With the rapid development of the national economy and social progress, shopping mall lighting has been paid more and more attention in the whole society. Shopping malls are generally relatively empty and large, composed of multi-storey buildings, generally divided into multiple areas, the bottom is generally an underground parking lot, and then online are food courts, shopping exhibition halls, etc. In the prior art, the lights in shopping malls are generally brighter, the lighting time is longer, the voltage is higher, and the power consumption is larger. However, each time period of the shopping mall is different, and the total flow of people in the shopping mall and the flow of people in each area are also different. , Many unmanned or sparsely populated areas also maintain high-intensity li...
