The invention relates to an electric light source technology, in particular to a solar-power-supply human body sensing automatic turning-on / off booth LED lamp group. The solar-power-supply human body sensing automatic turning-on / off booth LED lamp group is composed of N human body pyroelectric sensing automatic turning-on / off LED lamps of N booths. One booth illumination lamp is composed of a light-emitting diode LED lamp, a voltage-stabilizing chip, a human body pyroelectric sensor, a light-out delay circuit, a dimming pulse generator and a pulse PWM dimming high-power driving chip, wherein the solar power supply is connected with a storage battery through a counter-current preventing diode, an output of the human body pyroelectric sensor is connected with the light-out delay circuit, an output end of the voltage-stabilizing chip is connected with a power supply end of the dimming pulse generator, an output of the dimming pulse generator is connected with an enable end of the pulse PWM dimming high-power driving chip, an output of the pulse PWM dimming high-power driving chip is connected with the light-emitting diode LED lamp, and the light-emitting diode LED lamp is arranged in the booth illumination lamp. The solar-power-supply human body sensing automatic turning-on / off booth LED lamp group is suitable for viewing the booths by viewers in an exhibition hall, is turned on when a person is near, is turned off when the person leaves, welcomes the viewers with the turned-on lamps warmly, adds interest in exhibits and improves exhibition effect.
Description
technical field [0001] The invention relates to electric light source technology, in particular to an LED lamp group for a solar power source human body sensor automatic switch booth. Background technique [0002] Solar power is inexhaustible and inexhaustible, and it is rapidly developing and applied day by day. The ceiling lighting in the exhibition hall is difficult to see clearly the exhibits, pictures and texts in the booth, which is time-consuming and laborious, and the brightness has no dimming function. Contents of the invention [0003] The purpose of the present invention is to provide a solar power supply exhibition hall audience browsing booth lighting, a kind of solar power supply human body sensor automatic switch booth LED light group that lights up when people are in the booth, and turns off the lights after a delay when people leave. [0004] The technical solution of the present invention: a light group consisting of solar power, N booths and N human bod...
