【Abstract】 xenon lamp is also known as the HID , the first xenon lamp or by the original halogen bulbs injected xenon made, and now xenon lamp has been developed to non-filament high-pressure discharge, emit like the sun light, projecting the scope of both far and wide. Let us recall that under the headlights lighting history.
Car headlights illuminated the history of
Said home portable lamp is the first domestic car headlight lantern. In 1887, a pilot lost in the wilderness of darkness when a farmer with a portable lamp led him to go home In 1998, Columbia for electric cars to electric headlights and tail lights, headlights that gave rise to the initial can not be the first dimming headlights, so will some dazzling car. from the early development of acetylene gas headlamps to mirror today's free surface gas discharge headlamps, nearly 120 years experience.
The first generation - acetylene gas headlamps headlamp high-brightness contours, acetylene gas flame brighter than the light source at that time twice the brightness can be achieved, therefore, in 1925, previously used car headlights almost all acetylene headlamps.
The second generation - electric light sources
1913, with inflation spiral filament incandescent bulbs come out, because of its high brightness, to electric light sources has opened up broad prospects. However, due to time constraints of automotive electrical systems, until 1925, electric lighting was widely used.
Third Generation - Dual headlights light the wick at the intersection to address the headlamp glare caused by car drivers due to glare caused by traffic accidents and crashes of the serious problems, the emergence of dual headlamps light the wick, but not completely solve the problem with light car lights, cars pass this hanging head problem, and still is the most difficult automotive lighting technology to solve problems.
Fourth Generation - asymmetric beam headlamps headlamp system is a dual-light the wick symmetric beam system for the car will solve the process, the headlight not produce glare, but also to ensure good lighting on the road , 1932, the United States invented the asymmetric headlight, which is based on reference axis as the center, the light beam into two cars near to the side of the landing distance is short (that is, beam down to anti-glare), while the other side floor beam long distance (ie, beam elevation, which increases as the see).
Fifth Generation - Halogen headlamps with halogen bulbs first by the French automobile headlamp "Spey" produced in 1964, the working temperature of the filament allows higher than ordinary incandescent bulbs, luminous efficiency increased about 50%, life expectancy has doubled. Since then the production of automobile headlights lighting is also more halogen bulb uses the principle of the sixth generation - rechargeable xenon bulbs (such as the BEST charge xenon lamp , recommended)
BEST xenon lights , light bulbs filled with high quality within the inert gas xenon, and select high-quality tungsten and high-quality quartz glass tube, lamp life and brightness to play extreme. More than 3200 lumens brightness. Such a result does not change the original car lamp bulb form factor, it will not be allowed to have focus problems. This concentrating effect is very good bulbs, and K values at 4300K or more, soft colors, bright white light.
Seventh Generation - Xenon lamp bulb (recommended)
HID xenon lamp technology with high voltage discharge xenon (Xenon) poured into the quartz tube, and then swing through the sophisticated ballast through the three instantaneous increase of 12 volts to 23,000 volts or more, excited xenon tube electronics free, in two arc between the electrodes to form a bunch of super-light continuous light, so light colors brighter.
