Abstract
The invention discloses a delayed illuminating lamp capable of brightening and dimming gradually. The delayed illuminating lamp comprises 220V alternating current, a full-bridge rectification circuit, a start and delay circuit, a unidirectional thyristor triggering and control circuit and a unidirectional thyristor voltage zero-crossing guarantee circuit. A typical working mode of a common delayed illuminating lamp includes that the illuminating lamp is turned off after being turned on for working for a period of time, and the illuminating lamp is either turned on or turned off, so that the intermediate luminance for transition of on and off of the illuminating lamp does not exist. The working mode of abrupt on or off of the illuminating lamp has extremely bad influence on eyes of people particularly under the dark environment condition at night. The delayed illuminating lamp gradually gets brighter after being turned on and gradually dims after being turned off. The delayed illuminating lamp with the working mode has the advantages that the delayed illuminating lamp meets the need of adaptability of people's eyes; and the service life of incandescent lamps can be effectively prolonged, and the incandescent lamps are particularly suitable for working under the condition of overhigh voltage of mains supply at night.

Below specify this gradually bright delay illuminating lamp related relevant technologies content in implementation process of gradually going out.
Summary of the invention
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 present invention 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.
The circuit working principle: the right portions of the gradually bright delay illuminating lamp circuit that gradually goes out is made up of unidirectional controllable silicon S CR, diac KS and resistance R 3, resistance R 2, capacitor C 2, resistance R 1.When capacitor C 2 charging voltages reached the trigger voltage 35V of diac KS, diac KS punctured the generation trigger impulse, makes unidirectional controllable silicon S CR conducting, and incandescent lamp HA just has electric current to be passed through.
Delay circuit is by resistance R 1, constant was the charging circuit of 10～20s when electrochemical capacitor C1 formed; It can make capacitor C 2 increase with the rising of the voltage on the capacitor C 2 through the electric current of resistance R 2; Thereby the time that makes capacitor C 2 reach diac KS trigger voltage will reduce to 1ms gradually from 8ms; Thereby make voltage turn-on angle through incandescent lamp HA by 30, increase to 165 gradually.This ON time approximately needs 10s, and incandescent lamp HA is lighted gradually in this process.The value of capacitor C 2 is big more, and time of delay is long more; When resistance R 4, silicon rectifier diode D5 guaranteed that capacitor C 2 discharges into 2V when unidirectional controllable silicon S CR conducting, unidirectional controllable silicon S CR voltage zero-cross closes had no progeny, and capacitor C 2 is restarted charging.Transition suppresses the voltage at diode DW two ends and when being lower than 30V, does not give electrochemical capacitor C1 charging, begins the waits for too long of switching on to avoid incandescent lamp HA.
After breaking off starting switch SW, give capacitor C 2 chargings by electrochemical capacitor C1 through resistance R 2, make that unidirectional controllable silicon S CR can also conducting; Decline gradually along with electrochemical capacitor C1 voltage; The unidirectional controllable silicon S CR angle of flow reduces gradually, and incandescent lamp HA brightness deepening is gradually thereupon closed until circuit.
