Historical Changes of Automotive Lighting

Early Car Lights

In 1898, Boston held the first car show in the United States, the Columbia car in the United States as the lamp headlights and taillights, and so that the headlight was born. In 1916, an American named C•H•Thomas let the other driver can see gesture of his playing in the evening, a light bulb with battery mounted in the glove, and thereby turn signals humorous debut. In 1938, American Buick car fitted with a steering flash, and then only as optional accessories are installed in the rear of the car. Turn lights in front of the vehicle is also fitted until after 1940. The early automobile headlamps with tungsten incandescent lamp, the dim light can only supply slower car. A long time, in the domestic market, the incandescent has been the main source of all kinds of car lighting kits. Due to the unstable quality of incandescent, so many car accidents occurred every year in China, incandescent vacuum lamps will be phased out.

Halogen Lights for Cars

For nearly 20 years, the automotive lighting equipment halogen lamp (Halogen) is very popular. Each halogen lamp is composed of two sets of filament. The group is the main beam filament, straight forward shot to the mirror reflection of the light emitted by the lampshade. Another partial beam filament, the light emitted to the light shielding plate block to the upper part of the lampshade reflecting mirror, its rays are reflected out of the downward diffusion to the ground, and is not opposite to car drivers who cause dizziness. The disadvantage of the halogen lamp is used for a period of time after the light-emitting capability is gradually degraded. The disadvantage of this kind of auto strobe lights is too much power consumption and the heat bulb makes the lamp cover glass breakage, or lamp housing reflective coating peeling even rupture deformation due to thermal expansion.

Xenon Car Lights

After entering the 21st century, the automotive lighting also entered a new era. The xenon lamp came into being and for the first time equipped in Europe limousine. Compared with halogen lamps, the main difference of xenon lamp is that the xenon lamp through a gas ionization luminescence, the latter by heating tungsten light. Xenon car lamp has high reliability, and will not be affected by the car voltage fluctuations, and to improve road safety at night. Because no filament, the traditional filament easy to brittle fracture problem, life is much longer than ordinary halogen. In addition, the smaller headlamp volume given the automotive appearance design more creative space, car manufacturers also benefit from being able to use high temperature low standard plastic and reduce energy consumption. Therefore, the xenon lamp has gradually become the main trend of the modern automobile headlights.
