At first in the car can illuminate the road ahead of your life is not the electric light, but the steam lamp. Due to the stability of the early light is poor, brightness is not steam lamp, so with kerosene as the main energy of steam lamp is used for car lighting, but the disadvantage of steam lamp is also very obvious, first of all, steam lamp need to preheating, not light immediately, but steam lamp has been used N for many years, until the 1930s, steam lamp was gradually replaced by lights, retire!

 Light can replace steam lamp, there are two main reasons, first, with the development of technology, the stability of the light got a certain degree of solution, but the main reason is that the light can be lit at any time, no delay, and can use multiple light light switching function, perfect interpretation of the sentence " illuminate your beauty!"Not only is it more humane, but it also greatly reduces the occurrence of traffic accidents when driving at night. But at this time the light is still incandescent, low efficiency, short life, need to be further improved.

 With the development of technology, the upgraded version of incandescent —— halogen lamp appeared. Halogen lamp is injected with iodine or bromide into the original incandescent lamp, which not only greatly enhances the life of the filament, but also further saves energy by more than 30%. At this time, for the use of headlights demand, halogen lamp lighting brightness is enough, reliable work, is the best comprehensive cost-effective product. To this day, halogen lamps are still used in most family cars.

 Human beings will never be satisfied with the status quo, are still struggling to break through the possible. In the 1990s, a large enterprise took the lead in successfully porting xenon lights to car lighting and introduced xenon headlights.

 Xenon lamp has higher brightness, lower energy consumption, longer life, has a number of advantages. However, xenon lamps are manufactured for halogen lamps, so they have long been only used in high-end models; on the other hand, the physical spectral penetration of xenon lamps is average, and the help of halogen lamps is still needed in foggy weather, which cannot completely replace halogen lamps.

 Xenon lamp was originally introduced to China from Europe and the United States, in the automotive aftermarket development, nearly ten years, has been known as the industry "profiteering industry", which shows that the xenon lamp industry is not normative. A few years ago, because the consumer understanding of xenon lamp is not enough, mainly consider how to brighten the brightness of the headlight, is more sensitive to the price and no requirements for product quality. The fake and shoddy products in the market mainly imitate domestic brands; in recent years, xenon lamp is gradually accepted by more owners, many middle and high-end owners have modification demand.

 In the xenon headlights appeared only more than ten years, LED headlights soon entered people's vision, LED headlights have higher luminous efficiency, low energy consumption, life is far more than any bulb. Since the first assembly of LED headlights to the production vehicle 10 years ago and now, the manufacturing cost of LED headlights has decreased significantly, which is now lower than the manufacturing cost of xenon lamps, and is a representative of the new generation of lighting.
