In recent years, with the development of automobile technology, LED headlights have become increasingly popular. Compared with halogen lamps and xenon lamps, LED lamps that use chips to emit light have been comprehensively improved in durability, brightness, energy saving and safety. Therefore, it has become the new favorite of manufacturers with the strongest comprehensive strength. Nowadays, in order to show their luxury, many new cars will emphasize that they are equipped with LED lights.

You know, in the past few years, high-end models were equipped with xenon headlights. However, looking at the models on sale today, LED headlights are basically used, and xenon headlights are still used, only a few models, DS9 (low-profile), Kia KX7, etc.

However, as the most "primitive" halogen headlights, they can still be seen on many models. Some brands, such as Honda and Toyota, still use the headlight combination of low-beam halogen and high-beam LED. Why are halogen lamps not replaced by large areas, but xenon headlights with more "strength" will be gradually replaced by LEDs?

On the one hand, halogen headlights are cheap. You know, halogen lamp evolved from tungsten filament incandescent lamp, which is a "light bulb" in plain English. Moreover, the technology of halogen headlights is quite mature now, and car companies are willing to use it in some models that lower the price. At the same time, the maintenance cost of halogen lamps is lower, and it still has a market for some users with limited budgets.

Referring to the data on the industrial information network, it is also a headlight, and the price of a halogen lamp is about 200 to 250 yuan; Xenon lamp 400 to 500 yuan; LEDs are naturally more expensive, costing 1,000 to 1,500 yuan.

In addition, although many netizens think that halogen lamps are not bright enough and even call them "candle lamps", the penetration rate of halogen lamps is much higher than that of xenon lamps and LED lamps. For example, the color temperature of LED lamps is about 5500, that of xenon lamps is more than 4000, and that of halogen lamps is only 3000. Generally speaking, when light is scattered in rain and fog, the higher the color temperature, the worse the light penetration effect, so the halogen lamp penetration effect is the best.

On the contrary, although xenon headlights have improved in brightness, energy consumption and life span, the brightness is at least three times that of halogen headlights, and the power consumption is much smaller than halogen headlights, but it also means that its cost is bound to be higher, so it was mainly used in middle and high-end models.

However, behind the high cost, xenon headlights are not perfect, and it has a fatal disadvantage-astigmatism. Therefore, xenon headlights should generally be used in conjunction with lens and headlight cleaning, otherwise it is hooliganism. Moreover, after xenon headlights are used for a long time, there will be delay problems.

Generally speaking, halogen headlights, xenon headlights and LED headlights have their own advantages and disadvantages, which can be roughly summarized as follows:

From this point of view, the outstanding cost-performance advantage of xenon headlights is the biggest reason for their elimination. In terms of cost, it is far less cheap than halogen lamps, and in terms of performance, it is not as reliable as LED lamps. Of course, LED headlights also have defects, such as they are not full-spectrum light sources, the light frequency is relatively single, and the requirements for heat dissipation are high. As more and more models adopt LED lights, their sense of luxury and high-grade is gradually weakened. In the future, laser lighting technology may be further popularized in luxury brands.
