Many sellers will emphasize that this car is equipped with LED headlights when selling cars. Of course, the price will be slightly higher. So what are the characteristics of halogen lamps, xenon lamps, LEDs, and laser lights? Is the money worth it?
▎Halogen headlights
Halogen headlights are incandescent lamps with halogen elements added in plain terms. The principle of tungsten halogen cycle is used to eliminate the blackening of the incandescent lamp shell. Halogen headlights are the most common type of headlights in automobiles, and are more common in models with a price of less than 200,000 yuan and low-end models of some high-end brands.
There are many advantages, cheap, fast lighting speed, high visibility in rainy and foggy days, but the disadvantage is that it is too LOW, and it is really not tall enough.
▎Xenon headlights
Xenon lamps have been the most popular in the modification industry in the past few years. Many halogen lamp owners have converted their headlights into xenon lamps. Because the light source is white and the lens effect is added, it looks more beautiful, and the night lighting effect is also better. Clear.
The xenon lamp uses the light emitted by the xenon discharge as the light source. Although it has the advantage of saving electricity, it takes time to light up. This is a major drawback of xenon lamps, and the cost is relatively high. As the mainstream configuration of high-end models, it has gradually been used as LED headlight Replaced.
▎LED headlights
The Chinese name of LED is light-emitting diode. In fact, it has always been used in automobiles. In 2008, the Audi R8 was the first model to use all-LED headlights. Since LED headlights have become popular, the shape of the lights has become more beautiful. Huan, various lighting forms emerge in endlessly.
Moreover, LEDs are more energy-efficient, brighter, light up quickly, and can debug a lot of illumination modes, which is why it began to replace xenon lamps and become the mainstream configuration of high-end models.
However, LED headlights are not without their shortcomings. They generate a lot of heat, and their luminous efficiency is also affected by high temperatures, so they are usually equipped with radiators, which indirectly causes the disadvantage of high costs.
Laser headlights
The biggest advantage of laser headlights is the long exposure distance, but it is precisely because the illumination is too far, the laser headlights are usually not turned on when driving at low speeds, and domestic regulations even limit the distance to 475 meters.
Laser headlights have all the advantages of LED headlights, and are smaller in size, which can leave more space for designers to design the front face part.
However, the price of laser headlights is indeed a flaw in the current situation. At present, only some flagship models of luxury brands are equipped, and it will take time to become as popular as LED headlights.
