1 2 汽车照明系统的设计 摘 要 随着社会的发展和人们生活水平的不断提高，人们对汽车的要求已不仅仅局限于性能，成本，而是越来越多的要求现代汽车更加安全，更加环保，更加人性化。汽车生产商们也正在用更安全、更环保、设计更精美以及更省油料等优点来吸引用户。而同时，新车款型也必须符合最新的规定，这就导致了新技术不断得到应用。作为汽车的三大安全件之一，汽车照明系统是最主要的主动式安全装置，对传统汽车照明系统的改进和创新也日益成为全世界汽车厂商研究的热点问题。因此，如何使汽车照明智能化，驾车更安全，更舒适就成为一个十分紧迫而又有重大现实意义的课题。 Abstract With the development of society and improvement of living standards, people'srequirements of the vehicle is not limited to performance, cost, but more and more requirements of modern cars safer, more environmental protection, more humane. Car makers are using more safe, more environmentally friendly, moreexquisite design and more advantages to attract users of oil crops. But at the same time, the new car models must also be consistent with the provisions of the latest, this leads to the new technology had been used. As one of the three safety car, car lighting system is active safety device of the main, to the improvement and innovation of traditional automotive lighting system is becoming a hot problem of automobile manufacturers worldwide research. Therefore, how to make the automobile lighting intelligent, driving safer, more comfortable to become has the important practical significance a very urgent task. 3 1.前言 汽车照明系统是汽车安全行驶的必备系统之一。它主要包括“外部照明灯具、内部照明灯具、外部信号灯具、内部信号灯具等。汽车照明的发展史大体上经过如下四个阶段：汽车灯具的演变随着汽车光源的更迭而发生。 第一代汽车照明系统是由燃料（蜡烛、煤油或乙炔）直接燃烧发光。但存在发光效率很低、光强弱、性能不稳定、操作复杂等明显缺点。能满足早期车灯的要求。 第二代汽车照明系统是白炽灯。...
