现在,一般的汽车前照灯都还是采用卤钨光源。新的川D汽车前照灯则是采用高强度放电(HighIntensity olsch哩e)光源。为什么在汽车前照灯中要采用比卤钨光源更亮、寿命更长的HID光源呢?具体说来,有以下几方面的原因: (l)节电的需要一随着汽车电气化的发展,汽车中用电的部件增加,因此有必要降低单个装置的耗电量,尤其是特别耗电的前照灯。 (2)为了安全和经济,希望光源有更长的使用寿命一随着高速公路网的形成,夜问长距离行驶的机会增加,前照灯使用频率提高,因而对光源使用寿命的要求也随之提高。很显然,光源的寿命越长,车辆行驶的安全性越高。另外,如果光源的寿命长到可以与整车的寿命相比拟,也就是说在汽车的寿命期内无需更换光源,免去了这方面的维修费用,就更加经济。
Now, the general car headlamps are still using halogen light source. The new Chuan D car headlight is the use of high intensity discharge (High Intensity olsch mile e) light source. Why in the automotive headlamps to use halogen light source brighter, longer life HID light source? Specifically, the following reasons: (1) the need for a power-saving With the development of automotive electrification, As the number of components used in the car increases, it is necessary to reduce the power consumption of a single unit, especially for a particularly power hungry headlamp. (2) In order to be safe and economical, it is hoped that the light source will have a longer service life. With the formation of the expressway network, night interrogation increases the chances of traveling long distances and the frequency of use of the headlamps increases, so that the service life of the light sources Improve. Obviously, the longer the life of the light source, the higher the safety of the vehicle. In addition, if the light source life can be long compared with the life of the vehicle, which means that in the life of the car without having to replace the light source, eliminating the need for maintenance costs in this area, it is more economical.
