Abstract

The invention relates to an electric light source technology, and specifically relates to a solar power supply human body sensing bookshelf light-modulation LED lamp. The solar power supply human body sensing bookshelf light-modulation LED lamp comprises an LED lamp fixture, a solar power supply, a voltage stabilizer, a human body pyroelectric sensor, a light-off time-delay circuit, a light-modulation pulse generator and a PWM light-modulation high-power driving chip, wherein the solar power supply is connected with a storage battery via an anti-reversing diode, the base electrode of a triode VT2 is connected with reference voltages of a voltage-stabilizing diode via a resistor R9, the output of the human body pyroelectric sensor is connected with the light-off time-delay circuit, the output of the light-off time-delay circuit is connected with a relay J1, the output end of the voltage stabilizer is connected with the power supply end of the light-modulation pulse generator, the output of the light-modulation pulse generator is connected with the enabling end of the PWM light-modulation high-power driving chip, the output of the PWM light-modulation high-power driving chip is connected with the LED lamp fixture, and the LED lamp fixture is arranged in a bookshelf. The solar power supply human body sensing bookshelf light-modulation LED lamp is applied to bookshelf illumination, the lamp is lighted in the presence of people and is turned off when people leave, and thus time and electricity are reduced.

Description

technical field [0001] The invention relates to electric light source technology, in particular to a solar power source human body sensing bookcase dimming LED lamp. Background technique [0002] Solar power is inexhaustible and inexhaustible, and it is rapidly developing and applied day by day. The bookcase is illuminated by incandescent lamps or fluorescent lamps, and the manual switch is easy to forget to turn off the lights. Not only does it consume a lot of power, but the life of the bulbs is short, and the brightness lacks a dimming function. Contents of the invention [0003] The purpose of the present invention is to provide a kind of solar power supply human body sensing bookcase dimming LED light which is powered by solar power and the light is on when people are looking for books in the bookcase, and the light is turned off after a delay when the person leaves. [0004] Technical solution of the present invention: including solar power supply, light-emitting di...
