HID is the English abbreviation of High intensity Discharge high pressure gas discharge lamp, which can be called heavy metal lamp or xenon lamp. Its principle is to fill the UV-cut anti-ultraviolet crystal quartz glass tube with a variety of chemical gases, most of which are inert gases such as xenon (Xenon) and iodide, and then through the booster (Ballast) The 12-volt DC voltage on the car is instantly pressurized to a 23000-volt current, and the xenon electrons in the quartz tube are excited by the high-voltage amplitude to generate a light source between the two electrodes, this is called gas discharge.

The white ultra-strong arc light produced by xenon gas can increase the color temperature of the light. Similar to the sun's light in daylight, the current required for HID operation is only 3.5A, the brightness is three times that of traditional halogen bulbs, and the service life is better than Traditional halogen bulbs are 10 times longer.

The color temperature of xenon lamp is similar to that of sunlight, but it contains more green and blue components, so it presents blue and white light. This blue-white light greatly increases the brightness of road signs and signs.

● HID is three times higher than the brightness efficiency of halogen lamps, which has a significant effect on improving the visibility of driving at night and in fog.

● The luminous flux emitted by the xenon lamp is more than twice that of the halogen lamp, and the efficiency of converting electrical energy into light energy is also more than 70% higher than that of the halogen lamp, so the xenon lamp has a relatively high energy density and light intensity, and the operating current is only halogen. Half of the lamp. The increase in the brightness of the car lights also effectively expands the visual range in front of the car, thereby creating safer driving conditions.

● Power saving 1/2, halogen lamp consumes less than 60W of power, xenon lamp only 35W of power.

●Since the xenon lamp has no filament, there will be no problem of being scrapped due to the broken filament. The service life is much longer than that of the halogen lamp. The service life of the xenon lamp is equivalent to the entire running time of the car during the average service life.

●Once the xenon lamp fails, it will not go out instantly, but will go out gradually by dimming, so that the driver can win time in the dark and pull over urgently.

● The xenon lamp will not produce excess glare and will not cause interference to oncoming drivers.
