汽车车灯为汽车行驶必不可少的安全部件,在汽车主动安全方面的作用至关重要。80年代后期伴随高亮度发光二级管技术的出现,LED在汽车外部照明的应用成为可能。LED可靠性强、使用寿命长、色纯度高、响应速度快、体积小便于设计等优点,使其在车外照明方面得到越来越普遍的应用。进入21世纪,LED车灯已经成为汽车潮流的新宠,被广泛应用于转向灯、制动灯、前照灯等信号灯具上。本产品是基于研究高亮度LED汽车灯驱动与控制电路的基础上,实现基于LED汽车灯的车联网系统,实现相邻行车之间通过车灯进行光通信,在前后车辆间传递车辆状态、前方路况、语音等信息。 Car lights are indispensable for the car driving safety components, the role of active safety in the car is essential. With the advent of high-brightness LED technology in the late 1980s, the application of LEDs in automotive exterior lighting became possible. LED reliability, long life, high color purity, fast response, small size and easy to design advantages, making it more and more common in the car lighting applications. Enter the 21st century, LED lights have become the new darling of the car trend, is widely used in turn signals, brake lights, headlamps and other signal lamps. This product is based on the study of high-brightness LED vehicle lamp driving and control circuit based on the realization of car-based LED vehicle network system to achieve adjacent traffic between the lights through the optical communication between the front and rear vehicles to pass the vehicle state, the front Traffic, voice and other information.
