Description
Technical field
The utility model belongs to the electrical application technology field, is about a kind of gradually bright delay illuminating lamp that gradually goes out.
Background technology
Its typical working method of common delay illuminating lamp: generally being illuminating lamp extinguishes after work a period of time lighting the back automatically, illuminating lamp or light, or extinguish, the light on and off intermediate luminance of illuminating lamp does not have transient state.This working method especially under night pitch-dark environmental condition, light suddenly or extinguish people's eyes influence very outstanding suddenly by illuminating lamp.Can design a kind of illuminating lamp and when opening, light at leisure, illuminating lamp extinguishes when closing at leisure.If realize such working method, one meets the adaptability needs of people's eyes; Two can effectively prolong the useful life of incandescent lamp, and incandescent lamp is gradually bright gradually to go out and be particluarly suitable for working under the too high situation of line voltage at night.
Below specify this gradually bright delay illuminating lamp related relevant technologies content in implementation process of gradually going out.
The utility model content
Goal of the invention and beneficial effect: its typical working method of common delay illuminating lamp: generally being illuminating lamp extinguishes after work a period of time lighting the back, illuminating lamp or light, or extinguish, the light on and off intermediate luminance of illuminating lamp does not have transient state.This working method especially under night pitch-dark environmental condition, light suddenly or extinguish people's eyes influence very outstanding suddenly by illuminating lamp.The utility model is that a kind of illuminating lamp lights when opening at leisure, and illuminating lamp extinguishes when closing at leisure.Realize that such working method advantage is: one meets the adaptability needs of people's eyes; Two can effectively prolong the useful life of incandescent lamp, and incandescent lamp is gradually bright gradually to go out and be particluarly suitable for working under the too high situation of line voltage at night.
