Xenon lamp, short for HID gas discharge lamp, was first used in air transportation. But it has been used in large quantities in automobiles for more than ten years.
It was developed by Haila in the early 1990s. The principle of xenon lamp is quite different from halogen lamp and incandescent lamp.
It does not have filaments, but uses high-voltage positive and negative electric stimulation of xenon in the bulb to react with rare metals and then emit light, as we usually see.
The tiny glass ball in the xenon lamp tube is the source of the light of the xenon lamp, which is filled with xenon and a small amount of rare metal. But xenon lamp due to technology
The technology content is higher, so it is more expensive than ordinary halogen lamp and incandescent lamp in price.
Halogen lamps began to be used on automobiles in the 1970s. Their light-emitting principle is very similar to that of ordinary incandescent lamps, i.e. through spiral tungsten in the lamp tube.
When the filament is heated, its luminous intensity is limited by the melting point of the tungsten filament itself. Generally speaking, to increase the brightness of halogen lamps, not only tungsten wires should be added.
The resistance number and the melting point of tungsten wire must be increased. The tungsten filament of halogen lamp has higher melting point than that of common incandescent lamp, so its brightness is higher than that of common incandescent lamp.
The latter.
The main differences between xenon lamp and halogen lamp are as follows:
1. Xenon lamp is illuminated by high voltage arc discharge, so Xenon lamp needs to be equipped with additional electronic control starter outside the lamp, commonly known as
Stabilizer, because it needs 23,000 volts starting voltage to light xenon lamp, while ordinary vehicle halogen lamp only needs 12 volts working voltage stabilizer as bulb.
In addition, as a high-voltage electrical device, the stabilizer itself has an important influence on the reliability of the whole set of xenon lamps.
Security is also very important.
2. Xenon lamp has a long life, but because it does not work independently, the quality of stabilizer is directly related to the life of the whole system.
Life is long. The inferior stabilizers sold on the market can not guarantee the same life as xenon bulbs, but also produce strong electromagnetic interference when working.
Xenon bulbs are seldom damaged, but they are filled with high-pressure Xenon gas up to 6 atmospheric pressures and a certain amount of mercury and metal halides if they occur.
Explosion or leakage can pollute the environment.
