Abstract
The utility model provides a transistor flash device for vehicles. The transistor flash device for vehicles is suitable for the turn light of a vehicle, and the vehicles of 6 volt to 24 volt are universal. A VMOSFET transistor is adopted as a switch, which can effectively suppress the surge current of an electric bulb, and lengthens the lifetime of the electric bulb. The both ends of the transistor flash device for vehicles are leaded out wires. The transistor flash device for vehicles can directly substitute an ordinary twinkling device for vehicles.
Description
The utility model belongs to the automobile transistor flasher, is suitable for flasher usefulness, 6～24 volts of automotive universals.
Flasher is a filament bulb, and cold and hot state resistance differs greatly, and can produce very big surge current in the flash of light process, to bulb life is reduced.Existing automobile transistor flasher all can not solve this difficult problem.
The purpose of this utility model is to provide a kind of can effectively cut the system surge current, prolongs the transistor flasher of bulb life.
Accompanying drawing is a basic circuit of the present utility model.
The course of work is: behind the plugged, electric current is through diode D1, resistance R1And turn to bulb to capacitor C1Charging, because electric current is very little, inoperative to turning to bulb. Work as C1When both end voltage reaches 555 time base circuit operating voltage, by 60-80 time/minute oscillator work that 555 time base circuits form, output control VMOSFET transistor turns/cut-off, steering indicating light is lighted during conducting, breath goes out during cut-off, produces 60-80 time/minute flash effect.
Diode D in the circuit
1Be isolation diode, effect is when the VMOSFET transistor turns, prevents C
1Discharge guarantees 555 time base circuit normal operation.Resistance R
1Play metering function, stabilivolt D
2Play the pressure limiting effect, to protect 555 time base circuits.
Because the VMOSFET transistor itself has constant-current characteristics, so the surge current of bulb is subjected to placing restrictions on of device on state current, actv. has suppressed surge current, has prolonged bulb service life.
The utility model is the two ends pig-tail wire, can directly substitute common Der Blink und Abblendschalter, because its life-span of contact pointless also far surpasses common Der Blink und Abblendschalter.
Claims (1)
- A kind of automobile transistor flasher is characterized in that:A, employing VMOSFET transistor are made switch.B, be the two ends pig-tail wire.
