Supermarket shopping mall human body infrared sensor switch dimming led light group

Abstract

The invention relates to an electric light source technology, and specifically relates to a supermarket and emporium human body infrared induction switch light-modulation LED lamp group. The LED lamp group comprises a lamp group composed of N counter N human body infrared induction switch light-modulation LED lamps. Each counter human body infrared induction switch light-modulation LED lamp is composed of an LED light fixture, a 7805 voltage stabilizing chip, an AMNI human body infrared inductor, a light-off time-delay circuit of a 555 time-base chip, a light-modulation pulse generator of a 555 time-base chip, a PT4105 PWM light-modulation high-power driving chip, a relay J and a power adapter, wherein the output of the human body infrared inductor is connected with the light-off time-delay circuit, the output of the voltage stabilizing chip is connected with the power supply end of the light-modulation pulse generator, and the output of the PWM light-modulation driving chip is connected with the LED light fixture. The supermarket and emporium human body infrared induction switch light-modulation LED lamp group is applied to counter browsing during shopping in a supermarket and an emporium, lamps are lighted in the presence of people and are turned off when people leave, lighted lamps send a welcome message to customers, the customers can choose goods to their hearts' content, and thus their purchase interest is enhanced.
