Description

Light controller for automobiles

The utility model belongs to the light indication of a kind of motor-driven vehicle day, vehicle running in the night, the self-con-tained unit of conversion.

At present, motor-driven vehicle day, vehicle running in the night, meeting, overtake other vehicles and when turning to, the conversion of its light that turns to indication, light all is to be pulled or pin is stepped on and finished by chaufeur, complex operation, and labour intensity is big, does not note just being easy to cause traffic accident slightly.

The purpose of this utility model is the deficiency according to above prior art, avoid cumbersome in the driver's operation, and a kind of day, vehicle running in the night, meeting are provided, do not need when overtaking other vehicles cumbersome manual operations can automatic beam change and automatically flash of light repeatedly, the light indication when turning to, automatically reset light self-con-tained unit.

The purpose of this utility model realizes by following approach, form receptor by two or more photo-transistors, be installed on the headstock, receive the wigwag that the other side sends a car, make the photo-transistor conducting, trigger circuit via aerotron and resistance composition, change optical signal into electric signal, be turned into bistable trigger-action circuit by being capacitively coupled to the control circuit of forming by aerotron, diode and resistance, the driving circuit that turnover voltage is formed via aerotron, diode and resistance, the work of driving relay, the far and near strong and weak conversion of automatic guidance light; When overtaking other vehicles, press prompting device K ₁, light just can strong and weakly automatically glisten repeatedly; When turning to, press prompting device K ₂, K ₃, left and right sides steering indicating light luminous energy was automatically reset after time expand.

The utility model has the advantages that: this device has day, vehicle running in the night, meeting, overtakes other vehicles, glistens automatically when turning to, becomes advantages such as automatically reseting of light and turning indicator light, and have that volume is little, easy to install, flexible operation, thereby alleviated the labour intensity of chaufeur greatly, lessen fatigue, guaranteed traffic safety.This device need only energized get final product work, does not need to add in addition power supply.

Concrete structure of the present utility model is provided by following accompanying drawing:
