Abstract

The invention provides a low-power fade-on and fade-off LED lighting lamp. The low-power fade-on and fade-off LED lighting lamp is characterized by comprising a 220V AC power supply, a 12V DC voltage stabilizing circuit, a startup and shutdown and control circuit and a light-emitting diode power drive circuit. The lighting lamp is turned on to reach full brightness or is suddenly powered off to extinguish during the dark night; and eyes cannot adapt at the moment, so that learning or resting of people is not facilitated; and the eyes of people are certainly affected. The lighting lamp which can slowly light up when a power supply switch is turned on, and slowly go out when turned off is designed. If the working mode is achieved, the eyes of people are not stimulated by strong light at night; the lighting lamp meets the physiological requirements of the eyes of people; and people can conveniently leave or go to bed when the lighting lamp fades off. The low-power fade-on and fade-off LED lighting lamp is completely or partially fabricated by discrete devices, so that the low-power fade-on and fade-off LED lighting lamp is simple in circuit, stable to work and reliable in performance, and is an energy-saving and practical technical scheme.

Description

technical field [0001] The invention belongs to the field of electronic technology and lighting technology, and relates to a low-power LED lighting lamp whose brightness gradually brightens and fades. 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 longer be st...
