根据美国国家公路交通安全管理局(NHTSA)公布的数据,在黑暗时段只有25%的汽车出行,但在此期间发生了超过40%的重大事故(死亡或严重受伤)。
)和欧盟委员会(EC)。
夜间驾驶可能会让任何人感到恐惧。
即使你的灯打开,迎面而来的交通眩光也很难看到。
幸运的是,前照灯系统的新发展,包括Pixel Light技术,正在帮助缓解这一问题。
Pixel Light不是依赖传统的电机控制光束调节,而是控制多个LED发光器,以提供更灵活,更灵活的操作方法。
通过LED的打开,关闭或调光,可以塑造车辆的前光束。
这与摄像系统相结合,可以增强驾驶员视线中道路标志,行人和其他物体的照明,同时最大限度地减少迎面而来的交通眩光,提高驾驶员,乘客和行人的安全性。
下图显示了没有(左)和(右)基于像素光的防眩光远光灯的照明系统。
正如您所看到的,Pixel Lights大大减少了来自迎面而来的交通的眩光,使夜间驾驶更加轻松和安全。

以下为原文

Only 25% of travel by car takes place in the hours of darkness, yet over 40% of all major accidents (with fatalities or serious injuries ensuing) occur during this time, according to figures published by the U.S. National Highway Traffic Safety Administration (NHTSA) and the European Commission (EC).  Night time driving can be intimidating to anyone.  Even with your lights on, the glare from oncoming traffic can make it difficult to see. Fortunately, new developments in front-lighting systems, including Pixel Light technology, are helping to alleviate this problem.
Rather than relying on the traditional motor controlled beam adjustment, Pixel Light controls multiple LED emitters to provide a more flexible and operationally efficient approach.  Through the turning on, turning off or dimming of LEDs it is possible to shape the vehicle’s front light beam.  This combined with camera systems can enhance illumination of road signs, pedestrians, and other objects in the driver’s line of sight, while minimizing the glare of oncoming traffic, improving driver, passenger and pedestrian safety.
The images below demonstrate lighting systems without (left) and with (right) Pixel Light-based anti-glare high beams. As you can see, the Pixel Lights greatly reduce the glare from oncoming traffic making it easier and safer to drive at night.
