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。 A bstract With the development ofsociety and improvement ofliving standards, people'srequirements ofthe vehicle isnot limited toperformance, 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 toattract users ofoil crops. But atthe same time, the new car models must also beconsistent with the provisions ofthe latest, this leads to the new technology had been used. Asone ofthe three safety car, car lighting system isactive safety device ofthe main, tothe improvement and innovation oftraditional automotive lighting system ing ahot problem of automobile manufacturers worldwide research. Therefore, how to make the automobile lighting intelligent, driving safer, fortable e has the important practical significance avery urgent task. 3 。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。 1879 年爱迪生发明白炽灯。汽车灯具发生了革命性的变化,1913 年美国首先将白炽灯技术应用在凯迪拉克汽车
