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.

Description

technical field [0001] The invention relates to electric light source technology, in particular to a human body infrared induction switch dimming LED lamp group in a supermarket. Background technique [0002] Supermarkets and shopping malls are full of goods on the shelves and containers, and it is difficult to see the goods and prices clearly under the overhead lighting, especially for the elderly and children, and the brightness does not have a dimming function, so it is time-consuming and laborious to buy goods. Contents of the invention [0003] The purpose of the present invention is to provide supermarket shopping mall container, shelf purchase lighting, shoppers browse the container, shelf automatic lighting, people leave a kind of human body infrared sensor switch dimming LED lamp group. [0004] The technical solution of the present invention: a lamp group consisting of N containers and N human body infrared sensor switch dimming LED lamps, one container human bod...
