Description

Energy-saving long-life signal lamp

The utility model is relevant with non-lamp for general lighting, and is especially relevant with the signal lamp of high and low voltage switch cabinet.

High-tension switch cabinet closes in advance at high-voltage switch gear, needs the signal lamp flashing light alarm after the accident tripping, but and switch when closing a floodgate normal operation signal lamp Chang Liangzuo indicator cock close a floodgate and use.Traditional signal lamp adopts white heat to add the flashing relay contact and drives the incandescent lamp flash of light.General electricity-saving lamp and relay can not be used.Because flashing relay wiring complexity, in the life-span short (being generally 800 times), incandescent lamp adds flashing relay power consumption too high (about 40W), and is too expensive.Can only input direct voltage, shared property is poor.

The purpose of this utility model provides a kind of energy-conservation, and the long-life, shared property is good, the signal lamp of the high-quality low-cost that can glisten automatically and not glisten.

The utility model is by light head 1, constant amplitude, the equal time oscillator 2 of having a rest, and power circuit 3 is formed.Squegger 2 has CMOS integrated circuit 4, and its 14 foot and 7 foots connect the positive and negative output terminal of power circuit 3, and its 4 and 10 foot connects the base stage of transistor BG.Be connected to resistance R 5 and R4 respectively between its 1 foot and 5 foots and the power circuit negative pole, capacitor C 1 is connected to 1 foot and the 4(10 of integrated circuit) enough between.

Power circuit of the present utility model 3 is by V1, V2, V3 three input ends, resistance R 1, R2, R3, diode D1, D2, the rectification that D3 and capacitor C 3 are formed, filtering circuit.14 foots of its two ends integrated circuit 4 and 7 foots, another output terminal is connected between the emitter and light head 1 of BG.

Integrated circuit 4 of the present utility model can be CD4011 or CO36 imports four Sheffer stroke gate cmos circuits, and light head 1 is the integrated encapsulated semiconductor luminotrons of φ 20 high brightness.

The utility model power is less than 2W, and the flash of light life-span is more than 1,000,000 times, can import AC and DC voltage, and versatility is good, and is energy-conservation, longevity.Flashing rate is per minute 60 times, can do flash of light automatically and not glisten AC and DC universal signal lamp, and price only is 1/20th of a traditional relay flashlight.

Following is the accompanying drawing of utility model:

Fig. 1 is circuit theory diagrams of the present utility model.

Following is embodiment of the present utility model:

The utility model can be from V1, V2, V3 input 6.3V-380V combined-voltage.From V1, during V3 end input combined-voltage, light head will be glistened by per minute 60 secondary frequencies.Switch to V2 and work as input voltage, during V3, light head is closed a floodgate as switch and is moved normal bright pilot lamp.

The AC and DC voltage of input is by R1, D1, and R3, the D3 step-down rectifier is given 1 four-footed and 7 foots of integrated circuit 4 after the filtering.IC1 among integrated circuit CD4011 or the CO36, IC2, IC3, four Sheffer stroke gates of IC4 and capacitor C 2 and C1, R4, R5 forms a constant amplitude, the equal time pierce circuit of having a rest.With IC3, the IC4 output terminal is connected to switch amplifier tube BG base stage, when positive pulse adds to the BG base stage, and the BG conducting, light head 1 is luminous.When undersuing was delivered to the BG base stage, BG ended, and light head 1 is extinguished not luminous.So go round and begin again, light head 1 is glistened with per minute 60 secondary frequencies.

When AC and DC voltage switches to V2, during the input of V3 end, electric current lead to R2, and D2 is luminous, D3, and R3 forms path, and light head Chang Liang can make switch and close a floodgate and normally move clearing lamp this moment.
