Abbreviations xenon headlamps are HID (High Intensity Discharge Lamp), is a new type of headlamp comprising xenon, also known as high intensity discharge lamp gas.
1. Xenon headlamps noun
Abbreviation xenon headlamps are HID (High Intensity Discharge Lamp), it is a new type of headlamp comprising xenon, also known as high intensity discharge formula Discharge lamps. By filling a gas in a variety of chemical UV crystal quartz glass tube, using high pressure, so that the separation is generated between the power source poles, to provide a stable vehicle headlight lighting system.
One curse of traffic accidents is insufficient headlights lighting. Statistics show that 60 percent have an accident at night, when traffic accident and another 22 percent occurred in poor visibility conditions. Xenon metal halide lamp With energy saving, high brightness, safety, comfort and long life advantages, and by the automotive industry and motorists love, extremely rapid development. There are many people listed as xenon headlights driving with ABS, airbags and other equipment willBackup device.
2. xenon headlamps emitting principle
automotive HID xenon lamp with traditional halogen different, is a high pressure discharge lamp, its light emission It is the use of positive and negative electrical stimulation xenon rare chemical reaction with light emission, and therefore there is a small glass ball inside the tube, which is filled with xenon gas and a little rare, as long as they are current to stimulate a chemical reaction, two who will send up to 4000K-12000K color temperature of light. It uses a special ballast, 12V car battery voltage generating trigger voltage above 23000V start the lamp. 0.8 seconds when starting luminance is 20 percent of the nominal luminance, luminance reaches halogen lamps, headlights and reaches 4 seconds or less than 80 percent of the nominal brightness. Ballast provides about 85V supply voltage to the lamp after the lamp is stably maintained at a constant lamp power operation.
3. Disadvantage xenon headlights properties
● under rain, snow, fog and other weather conditions less penetration halogen.
● Because of high brightness, it is easy to make the driver feel across the harsh, affecting their sight, there is a certain security risk.
● circuit complex and expensive. At the same time, once damaged, difficult to repair.
● dimming difficult.
● prolonged use, and easy to melt glass crystal, affect the service life.
4. Xenon lamp mounting Note
where the vehicle mounted ● avoid overheating.
● installed in a place away from the water to avoid close; because of excessive moisture can lead to leakage and aging stabilizer.
● good ventilation should be seated in a position to allow air flow to reduce the temperature of the ballast.
● placing the ballast bulbs distance should not be too far away, in order to reduce the line pressure who were divided into the light bulb has phenomenon.
● high-voltage part of the ballast should be wound, in order to avoid too large a magnetic field, and the impact of other automotive electrical equipment.
● original car headlights 10A fuse replaced 15-20A, to avoid excessive current when starting the original car fuse blows.
