汽车照明系统外文文献翻译、中英文翻译、外文翻译
汽车照明系统
一辆汽车的照明系统包括安装在前方、后方、两侧和顶部的照明和信号装置。在巷道和交通繁忙的地方行驶时，灯光可以明显地提醒其他司机和行人注意到车辆的存在、位置、大小、方向和驾驶者的意图和行驶速度。紧急车辆通常带有独特的照明设备，以提醒司机并表明交通优先。
历史
早期的道路车辆使用燃料灯作为车前照明灯。例如，第一次引进的XXXT型车的头灯和尾灯是用油灯。然而，几年后，所有车辆都改用电气照明。发电机在1908年第一次在汽车上使用，并在20世纪20年代普遍使用。制动尾灯在1915年开始研究，1919年投入使用。1936年至1940年，密封前照灯在美国作为唯一的标准类型。自动取消转弯信号从1940年开始使用。到了1945年，大灯和信号灯被纳入汽车结构。1960年，欧洲开发了卤素前照灯光源。1991年开始制作了HID车灯。1993年，大批量生产的汽车上安装了LED尾灯。21世纪的前十年里，LED等大量增加。
光源
白炽灯泡是所有汽车照明设备中使用的常见光源。许多类型的灯泡都被使用，制造商使用标准化的型数字来标识同规格的灯泡。灯座可能具有一个或两个联系人，塑料或玻璃楔形或双线循环或箍在管状"绳"灯具上使用刺刀类型。螺丝灯座灯永远不会在汽车应用中使用，因为它们会因振动而松动。方向灯与内部或外部镜片使用无的灯泡。相反，灯与无镜片可能使用红或黄的灯泡来为各种功能提供所需的颜的光。
通常，21到27瓦的灯泡生产280至570瓦（22至45平均球面光）用于停止，灯泡转，扭转前后雾灯，而4到10瓦的灯泡生产40到130瓦（3到10平均球面光）用于尾灯、停车灯、侧标志灯和侧转向灯中继器。
备了特殊的灯光，以便在紧急情况下提供更好的可见性和安全性。这些灯光通常包括旋转灯、闪光灯和闪烁灯，以及LED灯。LED灯在紧急车辆中的应用越来越普遍，因为它们提供更长的使用寿命和更低的能耗，同时也更加耐用和可靠。
LED在汽车照明中的应用越来越广泛。相比于其他灯泡类型，LED具有更长的使用寿命和更
好的耐振动性能，同时还可以实现更浅的包装。此外，LED在停车灯中的应用还可以提供更快的上升时间，从而提高了安全性能。然而，如果不显示这个更快的上升时间，可能会导致汽车追尾事故的发生。
LED最初被应用于汽车照明中心高位刹车灯，在80年代末开始。随着技术的不断更新和相关样式的需求增加，LED在乘用车上的其他信号功能也逐渐得到了应用。现在，LED已经被广泛应用于汽车尾灯、前转向灯、日间行车灯等各个方面。一些豪华车型甚至完全采用LED灯光，例如梅赛德斯-奔驰S级(W222)。
在汽车照明中，光的分配系统可以通过光导或光纤将光从单个源发送到需要的位置。这种分布式系统不仅可以应用于仪表板显示，还可以用于车门锁、窗口控制和杯架等项目。同时，高强度中央的光源也可以用于外部照明。

紧急车辆灯光在火引擎、救护车、警车、除雪车辆和拖车等车辆中得到了广泛应用。LED灯光在这些车辆中的应用越来越普遍，因为它们可以提供更长的使用寿命和更低的能耗，同时也更加耐用和可靠。特殊的灯光，如旋转灯、闪光灯和闪烁灯，也可以提高车辆在紧急情况下的可见性和安全性。
