Abstract
This utility model relates to a safety car light controller, comprising a microcontroller, an infrared digital signal receiving circuit, an infrared digital signal emitter circuit and a light-switching control circuit. The working principle of this utility model is when the far-reaching car light is used, the microcontroller initiates the infrared digital signal emitter circuit to emit specific digital signals, and at the same time the infrared digital signal receiving circuit begins to check the specific digital signals emitted by other cars continuously; when cars meet together, the infrared digital signal receiving circuit checks the specific digital signals emitted by cars from the other direction and sends signals to the microcontroller and the microcontroller changes the far-reaching car light into near-reaching light through the light-switching control circuit; after the car-meeting, the microcontroller immediately or after suitable time-delay changes the near-reaching car light into far-reaching light to recover the original condition through the light-switching control circuit. The utility model effectively decreases the traffic accidents in night driving because of the glare of the far-reaching car light and is very practical.
