Abstract
A vehicle controllable light controller can control the active state or the inactive state of the light control unit for controlling the vehicle by the means of light control or manual control, which solve the problem of the original manual switch malfunction after the prior light controller outputting a light opening signal. The utility model comprises a feather-touch circuit, a controllable light control circuit and an output circuit. The output terminal of the feather-touch circuit is connected with the control terminal of the controllable light control circuit. The output terminal of the light control circuit is connected with the control terminal of the output circuit. The output terminal of the output circuit is connected with the vehicle head big lamp and the instrument small lamp. The feather-touch circuit can control the controllable light control circuit. If the feather-tough circuit outputs work orders, the controllable light control circuit can work to realize the automatic control of the light. If the feather-touch switch does not output work orders, the light is controlled by the original switch due to the controllable light control circuit nonworking. In this way, the utility model can realize double control effect of manual control and automatic control.
Description
Affiliated technical field
The utility model is a kind of electronics package that is used for the control of vehicle light.
Background technology
The light-controller of present vehicle, be on former headlamp switch circuit, to be connected in parallel, manual headlamp switch can be realized the switch of lamp when signal is turned on light in the output of light-controller end, after signal is turned on light in light-controller output, hand switch is the get out of hand effect, and light-controller itself can not controlledly switch between work or off position.
Background technology
The utility model purpose is to provide a kind of can carry out work or off position control to light-operated part, makes vehicle light also can manually control the controllable type light controlling device automatically by light-operated control.
Scheme of the present utility model is: this device is formed by touching circuit, controllable light control circuit, output circuit, the mouth that touches circuit is connected with controllable light control circuit control end, controllable light control circuit mouth is connected with the control end of output circuit, and the mouth of output circuit is connected with the instrument lampet with automotive headlamp.By touching circuit the controllable light control circuit is carried out control, when touching the instruction of circuit output services, the work of controllable light control circuit, the automatic guidance of realization light; Touching not output services instruction of circuit, the controllable light control circuit is not worked, and light is still by the original switch circuit control of vehicle.
The utility model has the advantages that: by touching circuit controllable light control circuit control end is controlled, realized manually and the effect of two kinds of light-operated controls.
