whenBMW,BenzWhen the new generation of lighting system HID was launched in top-tier cars, people all over the world were eager for it! I wish I could also install a set of HID on my own car. What follows is that the upgraded version of the domestic Audi A6 also uses HID xenon headlights. In addition, many domestic refitting factories have also launched similar products, but Many people don't understand what makes xenon headlights unique, so let me analyze it for everyone. Let everyone discuss it together!
Everyone knows that currently on the marketcarNinety-nine percent of the halogen lamps used are from the 60s. Its light-emitting principle is the same as the light bulbs used in our homes. It relies on tungsten filaments to emit light, but it is limited to the fact that tungsten filaments cannot withstand high temperatures. Considering its melting point, Therefore, most of the original bulbs are set at 60W, and 60W bulbs can only emit 1000 lumens. If they are converted into 100W bulbs, at most 1200 lumens! To increase its lumen, it needs to be updated with new luminescent materials! But limited to the limitation of the car itself, if the wattage of the bulb is increased, it will have a negative impact on the car!
HID, the full name is a gas discharge lamp. The principle is like lightning in nature. The principle of HID light emission is to fill a quartz tube with a variety of chemical gases, most of which are inert gases such as Xenon and iodide. 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. When you look at the bulb carefully, you will find a spherical glass ball in the middle. By the way, it contains xenon gas, and the yellow one is rare metal! When the transformer is given a high voltage of 23000V, the xenon gas is broken down, and the ionized xenon gas will emit unimaginable light. The color temperature can be as high as 5000K-8000K, but the sun's light is only 5500K at noon. You can imagine how bright its lumen is!
So, what is the attraction of HID, let me provide you with a reference material below:
1. Three times the brightness output:
Generally, the halogen lamp emits up to 1000LM degrees, while in HID it is 3200LM degrees. For people who often drive at night, the safety factor is greatly improved, and the fatigue is greatly reduced!
2. Ten times the life guarantee:
If you are a car owner, you may have encountered the halogen lamp on the car suddenly does not light up, and the result is that the tungsten wire burns out. Indeed, because the light-emitting principle of the halogen lamp is caused by the tungsten wire heating, and the tungsten wire Under long-term high heat, it is difficult to guarantee that it will not be burnt and damaged; and the xenon lamp uses electric current to stimulate the gas to emit light, and basically does not generate excessive high temperature, so as long as the xenon gas is not used up, it can emit light normally, and it is not easy to damage! According to one item Studies have shown that even high-quality halogen bulbs have a lifespan of 400 hours at most, while ordinary HIDs have a lifespan of at least 3000 hours. Even in normal car usage, HID can be used for 6-7 years. time!
3. Energy saving
As we said earlier, halogen lamps generally have a power of 60W---100W, while in HID it is 35W. Isn't it the same as saving you gas money if you have less wastage? Especially in today's high oil prices, isn't it worth considering?
Let me talk about the misunderstanding of choosing HID! Many people think that the higher the color temperature, the brighter the brightness. In fact, when the color temperature is higher than 5000K, the brightness will change from white to blue. When the color temperature is 8000K, the light emitted by the bulb is purple. , And at 12000K, the light is blue, so I suggest that you still choose a color temperature of 5000K, especially in foggy areas, because the penetration ability of yellow is stronger than that of white.
