??Xenon bulbs -- the seventh generation (recommended for use)
??HID Xenon lights high voltage discharge technique xenon gas (Xenon) different machines quartz tube. Through sophisticated ballast transformers by three to 12 volts to 23,000 volts of electricity over an instant, Free electronic excitation tube arc in the two electrodes formed from a continuous super-luminous arc, the more so-bright color.
??Sixth -- full xenon bulb (BEST full xenon lights, would be to use)
??BEST xenon lamps, light bulbs filled with internal quality inert gas xenon gas. Tungsten and select high-quality and high-quality quartz glass tube, so that the service life and brightness bulb play their worst. 3200 lumen brightness above. Such bulbs because the bulbs have not changed the original vehicle dimension, it will not have the problem of not focusing. This bulb concentrating effect was very good, but K figure above 4300K, the color soft, white light.
??Fifth Generation -- tungsten halogen headlight
????Halogen Lamp with the first batch of bubble by the French automobile headlamp "Sbeineh" in the 1964 production. its operating temperature than ordinary incandescent lamp filament bubble allow high-efficiency increase by approximately 50%, life expectancy has doubled. After the pre-production vehicle headlamps lighting also adopt the principle of foam Halogen Lamp.
??Headlamp asymmetry near the fourth generation
????Headlamp system is nearly symmetrical double-wick - system, the car will solve the process, does not have a compelling Headlamp. guarantee the right path with good lighting, in 1932 the United States invented the asymmetric headlight. It is a benchmark for the center axis, the light beam into two cars near to the side of the ground a short distance (beam down, and thereby showing off), while the other side of the landing of long-distance beam (beam elevation, thereby increasing as see).
??3G -- double-wick Headlamp
????Headlamp due to the bright light at the intersection when the driver compelling cause traffic accidents and crashes caused serious problems Headlamp the double-wick, but did not completely solve the problem - the allocation of automotive lamps, Such vehicles will be suspended when the current problem, and still is the most difficult to resolve automobile lighting technology issues.
??The second-generation light source -- Headlamp
????Helical filament incandescent lamp with a 1913 inflatable bubble developed, which has a higher brightness, -- Headlamp light to open a broad prospect. However, due to time constraints the auto electrical equipment until 1925, they were widely used in electrical lighting.
??Headlamp first generation of acetylene gas
????Headlamp with high brightness profile, acetylene flame brightness light -- than the higher brightness can achieve double Therefore, in 1925 before it is used in almost all automobile headlamp acetylene Headlamp.
??Domestic mobile lights
????Reported a vehicle headlamps before the domestic mobile lights. In 1887, lost a pilot in the dark wilderness, One farmer primers using portable lights his home. 1998, Columbia put electric vehicles -- for the front lamps and rear lamps. This had the lights on, not the first former headlight dimmers. So when will some doubts. Headlamp acetylene gas from the early development of the free surface mirror of the contemporary gas discharge headlamp, experienced almost 120 years. |
