基于光的辅助驾驶功能的DLP智能激光大灯

Smart DLP Laser HeadLight for Light-Based Driver Assistance

随着高级辅助驾驶或自动驾驶时代的来临,汽车大灯对其他道路参与者进行信息的交互功能越来越重要。本文介绍了汽车前灯的高像素智能照明技术现状和发展趋势,并以RGB三基色激光为光源结合基于DMD的DLP数字光处理技术实现了像素智能大灯的开发,实现了1120lm的光输出,水平方向视场角20°,垂直方向6°,在25m屏测试获得100lx的峰值照度,装车后对其高精度的防眩目远光照明功能和基于光的辅助驾驶功能进行了测试。

The rising awareness of the driver’s safety and automated driving require the headlamp to be smart and be dynamic communication to the driver/pedestrian by printing/painting symbols in the road. In this paper, we will present our RGB laser DLP Headlight with DLP technology. And a single this module, which outputs 1 120 lm and provides a field of view of 20° horizontally and 6° vertically is implemented. It’s also get almost 100 lx @25m. We also will provide an overview of these functions about enhanced ADB and light-based driver assistance functions in our RGB laser DLP prototype test.
