A lot of cars are halogen headlights, most of them should be like this. We all know the disadvantages of halogen headlights. If they don't light up, there may be accidents when the road conditions are bad, so many people choose to refit them at the first time. Halogen headlights are as shown in the figure. They are yellow, especially low beam headlights. If the light doesn't turn up, you can't see the road at all. I've seen a person almost bump into someone, that's the light. From halogen, xenon to LED, OLED, laser headlight, LCD headlight, etc., automobile headlights are constantly evolving, but some people still keep the most traditional halogen lamp and are unwilling to upgrade. Why?
Many people say that halogen lamp is too bad, is it really so? In fact, it is not entirely the case. Halogen lamps are mature in technology and simple in structure, so the cost is very cheap, which gives people a feeling of special cheapness. But in fact, the effect of halogen lamps is not so bad, and the light is very soft. However, compared with xenon lamp and LED lamp, halogen lamp is indeed "simple" a lot, not only the light is weak, but also the appearance shape and appearance value are significantly poor. Especially after the intervention of lamp factories like Audi, LED headlamp is even more gorgeous, almost becoming the standard of all luxury cars.
First of all, we need to understand the difference between the three kinds of lights?
Halogen lamp: mature technology, simple structure, low price, soft and even light, convenient maintenance.
Xenon lamp: long service life, higher brightness, low power consumption. However, due to the complexity of the structure and the longer start-up time, the penetration in rainy and foggy days is also seriously reduced.
LED lights: energy saving, environmental protection, long life, durable, simple structure, smaller volume, but because the technology is relatively more complex, so the price is higher.
