The latest explanation of HID xenon lamp[汽车修理知识]

1. The concept of xenon lamp Xenon lamp is a new type of headlight containing xenon, also known as high-intensity discharge gas lamp, HID (IntensityDischargeLamp) in English.Its principle is to fill a UV-cut anti-ultraviolet crystal quartz glass tube with a variety of chemical gases, most of which are inert gases such as Xenon and iodide, and then pass it throughSupercharger(Ballast) The 12-volt DC voltage on the car is instantly pressurized to a current of 23,000 volts, 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 the so-called gas discharge. The white super-strong arc light produced by xenon gas can increase the color temperature of the light, similar to the sun's rays 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 longer than traditional The halogen bulb is 10 times longer. 2. Luminescence principle of xenon lamp (HID) carThe xenon lamp is different from the traditional halogen lamp. This is a high-pressure discharge lamp. Its luminous principle is to use positive and negative electricity to stimulate the chemical reaction of xenon and rare metals to emit light. Therefore, there is a small glass ball in the tube, which is the irrigation Full of xenon gas and a little rare metal, as long as they are stimulated by electric current to carry out a chemical reaction, the two will emit light up to 4000K-12000K. It uses a special ballast that uses the 12V voltage of the car battery to generate a trigger voltage above 23000V to start the lamp. The brightness of 0.8 seconds at start-up is 20% of the rated brightness, reaching the brightness of a halogen lamp, and the headlights can reach more than 80% of the rated brightness within 4 seconds. After the lamp is stable, the ballast provides a supply voltage of about 80V to the lamp to keep the lamp running at a constant power. 3. Performance characteristics of xenon lamp (HID) 1. High brightness: The general 55W halogen lamp can only produce 1000 lumens of light, while the 35W xenon lamp can produce 3200 lumens of strong light, the brightness is increased by 300%, and it has an ultra-long and ultra-wide field of view, bringing you unprecedented Driving comfort; make the night no longer dark and have a clearer vision, which can greatly reduce the driving accident rate. 2. Long life: Xenon lamp uses electrons to excite gas to emit light, and there is no tungsten wire, so it has a long life, about 3000 hours, which greatly exceeds the total hours of car driving at night, while halogen lamps only have 250 hours. 3. Energy saving: The xenon lamp is only 35W, and the light emitted by the 55W halogen lamp is more than 3.5 times, which greatly reduces the load of the car's power system, saves 40% of power loss, and correspondingly improves vehicle performance and saves energy. 4. Good color temperature: there are 4300K-12000K, etc. 6000K is close to sunlight, which is well received by users, while the halogen lamp is only 3000K, and the light color is dim and red. 5. Safety and reliability: Safety is the greatest charm of HID. Many car owners who have used HID responded that they installed HID lights to have a good sight line, and the safety of night driving was greatly improved. Mainly because the multiple beams and intensities brought by HID lights will be more effective than simple far and near beam settings, which can greatly improve the lighting in front of the car and illuminate the signs on the roadside. The importance of these to driving safety is unquestionable. . 6. Emergency, due to the different lighting principles of xenon lamp and halogen lamp, whenAccumulatorWhen there is a problem with the power supply, it will be turned off for a few seconds, so that the owner has a certain time to deal with the emergency.
