Abstract

The invention relates to a brightness fade-on and fade-off LED lighting lamp employing discrete components. The brightness fade-on and fade-off LED lighting lamp is characterized by comprising a 12V DC power supply, a lighting lamp turn-on and turn-off circuit, a composite amplifier circuit, an ultra-high brightness white light-emitting diode power drive circuit. The lighting lamp is completely turned on or suddenly extinguished due to a power failure in the dark night; and the eyes are very unconformable instantaneously, so that learning or rest of people is inconvenient and certain effects on the eyes of people are generated. The lighting lamp which is on slowly when a power switch is turned on, and is extinguished slowly when the lighting lamp is turned off can be designed. If the working mode can be achieved, the eyes of people are not stimulated by strong light in the night, the brightness fade-on and fade-off LED lighting lamp can accord with the physiological requirements of the eyes of people, and people can conveniently leave or go to bed when the lighting lamp gradually fades off. A brightness fade-on and fade-off LED lighting lamp circuit employing the discrete components has the advantages of being simple in circuit, stable to work and reliable in performance; and the circuit is completely fabricated by ordinary discrete components.

Description

technical field [0001] The invention belongs to the field of electronic technology and lighting technology, and relates to an LED lighting lamp with gradually brighter and darker brightness of discrete components. Background technique [0002] The typical working mode of the common lighting or delayed lighting is: either the lighting is turned on to full brightness, or the lighting is turned off automatically after a period of time, and the brightness between the lighting and the extinguishing of the lighting is not excessive. In the dark night, the lights are turned on at full brightness or suddenly cut off, and the eyes are very uncomfortable in an instant, which is not only inconvenient for people's study or rest, but also has a certain impact on people's eyes. Is it possible to design a light that can be slowly turned on when the power switch is turned on, and slowly extinguished when the light is turned off. If such a working mode can be realized, people's eyes will no...
