Problems solved by technology

Especially in a dark room at night, if the lights suddenly turn off and the pupils of the eyes shrink, they can't see anything instantly. This situation not only has an adverse effect on the eyes of people, but also is not conducive to falling asleep safely after going to the toilet.

Abstract

The invention provides a slow turn-on / off night lamp. The slow turn-on / off night lamp is characterized by comprising a 220V AC power supply, a starting, step-down and slow charging circuit, a unidirectional silicon-controlled trigger circuit, a full-bridge rectifier circuit and a unidirectional silicon-controlled control circuit. The typical working mode of a delayed lighting lamp is as follows: the lighting lamp is turned off after being turned on and working for a period of time, the lighting lamp is fully on or off and the brightness is free of a state for transition between on and off of the lighting lamp. Especially in a dark room at night, the lighting lamp is suddenly turned off due to a power failure, and people cannot see anything at the moment of contraction of pupils of eyes, sothat the condition has an adverse effect on people's eyes and is adverse to peaceful sleep after the toilet is used. The slow turn-on / off night lamp provided by the invention has soft light, the light of the night lamp is slowly brightened and then slowly dimmed when the night lamp is turned off, and the slowly dimming process lasts about 30s, so that the working mode is very suitable for the physiological needs of people's eyes.

Description

technical field [0001] The invention belongs to the technical field of electronic applications and lighting, and relates to a slow-on and slow-off night light. Background technique [0002] The typical working mode of the delay light: the light is turned off after being turned on and working for a period of time, the light is either fully on or off, and there is no excessive state of brightness between the light on and off. Especially in a dark room at night, if the lights are turned off suddenly, the pupils of the eyes will constrict and they will not be able to see anything instantly. This situation not only has an adverse effect on the eyes of people, but also is not conducive to falling asleep safely after going to the toilet. [0003] Can you design a lighting that lights up slowly when the lighting is turned on, and darkens slowly when the lighting is turned off? If such a working mode can be realized, first, it meets the physiological requirements of people's eyes. T...
