Solar Power Human Body Infrared Sensing Dresser Dimmable LED Lamp

Abstract

The invention relates to an electric light source technology, in particular to a solar-power-supply human body infrared sensing dresser dimming LED lamp. The solar-power-supply human body infrared sensing dresser dimming LED lamp comprises a light-emitting diode LED lamp, a solar power supply, a voltage-stabilizing chip, a human body infrared 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, a base of a triode VT2 is connected with a reference voltage of a voltage-stabilizing diode through a resistor R9, a collector is connected with a relay J2, an output of the human body infrared sensor is connected with the light-out delay circuit, an output of the light-out delay circuit is connected with a relay J1, 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 on a dresser. The solar-power-supply human body infrared sensing dresser dimming LED lamp is suitable for illumination of the dresser, is turned on when a person is near, is turned off when the person leaves, saves time and electricity, and adds fun to life.

Description

technical field [0001] The invention relates to electric light source technology, in particular to a light-adjustable LED lamp for a dressing table with a solar power source and an infrared sensor for a human body. Background technique [0002] Solar power is inexhaustible and inexhaustible, and it is rapidly developing and applied day by day. The dressing table 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, 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 solar power supply human body infrared sensing dressing table light dimming LED light that is powered by a solar power supply, and the light is on when the person is on the dressing table, and the light is turned off after a delay when the person leaves. [0004] Technical solution of the pr...

AI Technical Summary

Problems solved by technology

The dressing table is illuminated by incandescent lamps or fluorescent lamps. Manual switches are easy to forget to turn off the lights, which not only consumes a lot of power, but also has short bulb life and lack of dimming function.
