  Laser headlamps are close before their first introduction into real world traffic.But before they are going to be introduced into serial application Audis laser headlamps are used in motor racing for a final testing.In its first application, laser headlamps are used as additional main beam contributors only.The result is a typical motor racing demand: It has a high range of visibility with a small solid angle.For the serial car one can use the released laser headlamp racing concept.Additionally the safety requirements have to be checked and updated.New standards and specifications are necessary to exclude any danger for other road users such as bicyclist, pedestrians and motorists (who are not present on race tracks).Danger could be caused e.g.by coherent class 4 radiation outside the laser headlamp.In this paper, three points will be explained: 1.Mode of operation of laser headlamps2.Potential risks and failures 3.Safety solutions The results are new and have not been used before in any other headlamp technology.Key factors are several combined sensor signals, new sensor types and optical elements.

相比较传统的卤素灯和氙气灯,LED具有独到的优势,如寿命长,发光效率高,响应速度快,体积小,设计可塑性强等.近几年来,LED已逐渐被应用在汽车前照灯中,尤其是在高端车型中.然而,与传统光源相比,LED车灯也有必须考虑的独特问题,光色性能便是其中一个重要方面.由于其本身发光特性以及温度影响,LED车灯极易出现颜色漂移以及空间颜色不均匀的现象,这些现象不仅仅会影响整个车体的外观,也会带来安全隐患.本文

传统的汽车前照灯光学测量方法是将车灯固定于分布式光度计,或将车灯的光分布直接投到测试墙面上测试其空间光强和照度分布.此方法的缺陷是无法直观得到车灯光能量在路面的分布情况,必须通过照度和光强的转换得到路面的照度分布情况.而由于路面的反射特性并非完全朗勃散射,导致通过上述方法测得的照度分布数据和驾驶员看到的实际亮度分布存在不一致的状况.本论文探讨了采用面式成像亮度计测量路面亮度分布的方法.通过采用CC
