HID is the (HighIntensityDischarge) high-pressure gas discharge lamp abbreviation, often said: xenon lamp or xenon headlights, in the country, but also called: hernia or hernia lamp headlights. Since published in 1991, Germany's BMW car HID principle, the new 1995 Mercedes-Benz E-Class first application HID xenon lamp, launched in 1997 now BMW, BENZ, AUDI, LEXUS, all the HID as basic equipment. With the rapid development of automotive technology, computer, smart air conditioning, GPS, LCD DVD system audio, mobile phones, have gradually become the car's basic configuration. The equipment needs power, and power automotive lighting headlights is one of the largest auto parts. In order to reduce the load on car battery to extend battery life, more important is to improve the quality of automotive lighting, reducing visual fatigue of drivers, to ensure traffic safety. More than 15 million vehicles worldwide have installed a xenon lamp. Believe will continue HID xenon lamp and ABS brake system airbags, the car must be the assembly, known as the 21st century revolution in automotive lighting products.

Xenon lights on the market the brand more, the quality varies.

Divided into three main sources: 1. Europe. If Oushi Lang, Philips, EOS, etc. Very good reputation. EOS-originated in ancient Greek mythology, a symbol of a bright dawn goddess, in Europe particularly in Italy and France already has more users in luxury cars, and the number of users continues rapid growth, has been a growing number of cars worldwide modified market users and partners of all ages. 2 South Korea, the evaluation can still be 3 made. The quality of the other people present, domestic concerns, poor evaluation of teaching, especially in the summer, heat is more difficult. The difference between South Korea and Europe in the delay time lighting, Korea 2 seconds on only half a second just in Europe.

Experts suggest that consumers may choose in the choice of lamp light xenon headlamps, color temperature because of its high penetrating power, can improve nighttime driving safety. Xenon gas-discharge headlamps, also known as HID headlights, it is wrapped in a quartz tube with high-pressure xenon gas instead of the traditional tungsten filament, to provide a higher color temperature, lighting more together. As the high-pressure xenon lamp is used to form the current active xenon arc light beam can be sustained discharge between two electrodes glow. Ordinary car light bulb 65 watts of power, while only 35 watt xenon lamp, reducing nearly doubled. Xenon lamps can significantly reduce the burden of the vehicle power system.
