Electronic vehicle Dim Dimmer of the present invention is compared with similar prior art or product, has following feature: electronic vehicle Dim Dimmer action accurately, reliable, flexible and convenient operation, change light nature, the Dim Dimmer long service life.

Accompanying drawing is an electronic vehicle Dim Dimmer inner structure scheme drawing.

Below in conjunction with the embodiment accompanying drawing, this patent application technology is done one describe in detail.

Utility model electronic vehicle Dim Dimmer is made of three parts such as pulse amplifying circuit, bistable switching circuit, driving executive circuits.Pulse amplifying circuit is by button AN, resistance R ₁, resistance R ₂, aerotron BG ₁, capacitor C ₁Form.Bistable switching circuit is by aerotron BG ₂, BG ₃, resistance R ₄, R ₅, R ₆, R ₇, R ₃, R ₈, diode D ₁, D ₂, capacitor C ₂, C ₃Form.Drive executive circuit by diode D ₃, resistance R ₉, aerotron BG ₄, relay J forms.The electronic vehicle Dim Dimmer can be installed on the bearing circle.

The electronic vehicle Dim Dimmer is mainly used in the automobile night running and becomes the light aspect.When the automobile night running need be by the distance light dimming, click the button AN of pulse amplifying circuit, aerotron BG ₁End by saturated becoming, and from aerotron BG ₁Electric impulse signal of emitter output, and pass through capacitor C ₁Be coupled to the input end of bistable switching circuit, bistable switching circuit adopts the incoming direction of triggering mode control energizing signal, makes energizing signal can both be added to the base stage of turn-on transistor at every turn and adds less than the base stage by aerotron aerotron BG ₂Under high-beam condition, be to end, aerotron BG ₃Saturated, aerotron BG then ₃Collecting electrode and base stage all approach zero, through capacitor C ₁, C ₃Coupling, by diode D ₂Detect negative pointed pulse signal and directly be added to saturation conduction aerotron BG ₃Base stage, circuit reverses rapidly, aerotron BG ₂Become conducting, aerotron BG by ending ₃Become rapidly by conducting and to end, so aerotron BG ₃Collecting electrode, base potential rise rapidly near 12V by zero volt, this moment, supply current passed through resistance R ₅, diode D ₃, resistance R ₉Be added to BG ₄The base stage of aerotron makes aerotron BG ₄Base stage obtains the straight voltage of forward bias and conducting is saturated, drives the relay J adhesive, the open contact closure, and normally closed contact disconnects, so country beam L ₁Dead electricity " is gone out ", passing light L ₂Get electric " bright " by the relay J contact.

After treating that two cars are met, in the time of need becoming distance light by dipped beam, click button AN again, aerotron BG ₁By saturated by becoming, and from aerotron BG ₁Electric impulse signal of emitter output, and pass through capacitor C ₁Be coupled to the input end of bistable switching circuit, aerotron BG ₂Under the dipped beam state, be saturation conduction, aerotron BG ₃End, then aerotron BG ₂Collecting electrode and base stage all approach zero, through capacitor C ₁, C ₂Coupling, by diode D ₁The negative pointed pulse signal that detects is added to the saturated aerotron BG of conducting this moment immediately ₂Base stage on, so circuit counter-rotating again impels aerotron BG ₂End aerotron BG by saturated becoming ₂Collecting electrode, base potential rise near 12 volts aerotron BG by zero volt ₃Become conducting, at this moment aerotron BG by ending ₄Base stage is ended because of obtaining oppositely straight partially voltage, and relay J discharges, and normally closed contact is connected, and open contact disconnects, so country beam L ₁Get electric " bright " passing light L ₂Dead electricity " is gone out ", and automobile enters cruising.
