HID lights for auto parts

Xenon lamps are defined by the authoritative definition of car2100. High intensity discharge is a high-pressure gas discharge lamp that contains an inert gas mixture including xenon gas, and has no filaments. It is referred to as HID xenon lamp for short. It can be called a heavy metal lamp or a xenon lamp. The principle of its light emission is through an initiator and an electronic ballast, forming an arc between two electrodes and emitting light.

Xenon lamp lighting principle The Xenon lamp's lighting principle is in a UV-cut UV-resistant quartz glass tube filled with a variety of chemical gases, most of which are Xenon Xenon lamps and iodides, and then through the pressurization The ballast (Ballast) instantaneously boosts the DC voltage of 12 volts on the car to a voltage of 23,000 volts. After the high-pressure shock amplitude excites the electrons in the helium gas in the quartz tube, a light source is generated between the two electrodes, which is called a gas discharge. The white super-arc light produced by the helium gas can increase the color temperature of the light. Similar to the sun's rays in the daytime, the HID needs only 3.5A of current to operate and its brightness is three times that of the traditional halogen bulb. Halogen bulbs are 10 times longer.

Composition of Xenon Lamps HID xenon lamps are generally composed of lamp caps, electronic ballasts (also called ballasts, regulators, etc.)
1. Lamp head: If you look closely, you will find that there is no filament in the HID Xenon lamp head, and there is no problem of tungsten filament burning;
2. Electronic ballast: Using a 12V DC voltage of the battery, after a series of conversion, control, protection, boost, and frequency conversion actions, an ignition voltage of 23,000V is generated to ignite the lamp cap, and then maintain the 35V AC after lighting. Voltage;
3. Line group: generally made of flame-retardant materials, by increasing the cross-sectional area of ​​the power cord, improving the current through the ability to ensure the normal operation of the HID xenon lamp.

The advantages and disadvantages of the xenon lamp The white super strong arc light produced by the xenon lamp can increase the color temperature value of the light. Similar to the daytime sun light, the current required by the HID is only 3.5A, and the brightness is three times that of the traditional halogen bulb. Life is 10 times longer than traditional halogen bulbs.
Its prominent advantages are as follows:
● The color temperature of the xenon lamp ranges from 3000K to 12000K. The color temperature of 6000K is similar to that of sunlight, but contains more green and blue components, and therefore appears blue-white. This blue-white light dramatically increases the brightness of road signs and signs.
● The HID's brightness efficiency is three times higher than that of a halogen lamp, which has a significant effect on improving visibility at night and in fog.
● The luminous flux emitted by the xenon lamp is more than twice that of the halogen lamp. At the same time, the efficiency of conversion of electric energy into light energy is also more than 70% higher than that of the halogen lamp. Therefore, the xenon lamp has relatively high energy density and light intensity, and the operating current is only halogen. Half of the lamp. The increase in the brightness of automotive lights also effectively expands the visual range in front of the vehicle, thus creating safer driving conditions.
● Power saving 1/2, halogen lamps consume more than 60W of electricity, and xenon lamps require only 35W of electricity.
● Since there is no filament in the xenon lamp, there will be no problem of discontinuity due to broken filaments. The service life is much longer than that of a halogen lamp. The service life of a xenon lamp is equivalent to the entire operating time of an automobile's average service life.
● Once the xenon lamp fails, it will not go out instantly. Instead, it will be extinguished (or quickly lighted) by gradually dimming. This will enable drivers to win time in the night driving and take an emergency stop.
● Xenon headlights will not produce extra glare and will not interfere with oncoming drivers. Xenon headlights, also known as HID gas discharge headlights, use high-pressure helium gas wrapped in a quartz tube to replace traditional tungsten filaments, providing higher color temperature and more focused lighting. Because the xenon lamp uses a high-voltage current to activate the xenon gas to form a beam of arc light, it can continuously emit light between the two electrodes. The power of an ordinary car bulb reaches 55 watts, while the neon lamp requires only 35 watts, which is nearly 1 times lower. Xenon lamps can significantly reduce the burden on the vehicle's power system. The color temperature of car xenon lamp is between 4000K-6000K, which is much higher than that of ordinary car headlight bulbs. It has high brightness. The 4300K ​​xenon lamp's light color is white and yellow. Due to the low color temperature, the visual effect is yellowish, and the light penetrating power is stronger than the high color temperature lamp, which can improve the driving safety at night and in fog. When you drive in dark nights on a road with no light, the road is narrow and crooked. At this time, if your headlights will be brighter and shine farther, the safety of driving will inevitably increase a lot. The HID lamp HID is a new generation of headlamps developed based on nighttime driving safety.


The disadvantages of the xenon headlamps The xenon headlamps, as modified products, naturally have some drawbacks. For example, the modified Mitsubishi and Polaris will have poor light concentrating, BMW's fault light will light, Buick Grand Hyatt will burn computer boards, and some individual models will also automatically turn off and other adverse reactions. Tip: This is because the modified product is not ideal with the original car. It does not mean that the product cannot. As long as the product is light, it is good!

Instead of focusing on several factors:
1, is the light bulb and lamp cup with no file.
2, is not installed or debugging is not good.
The fault light is because the original car's lamp has a large power loss (55W), and the power of the xenon lamp is low (35W), so the power of the xenon lamp is not enough and the alarm is reported. As the xenon lamp, its starting current is 8A, and the original car is 6.2A Qicheng So the original car's line settings do not match. Need to 4S shop to change the circuit mode. Automatic flameout is caused by excessive starting current and electromagnetic interference. This can be achieved by removing the ballast from the engine during installation or changing a low-current starter ballast! Basically all the situations can be solved.
