What is the difference between LED car headlights, xenon headlights and halogen headlights?

From the most basic halogen lamps, to advanced xenon lamps, to the new force full LED lamps, LED car headlights have been upgraded from generation to generation, and the cost is getting higher and higher, but the actual illumination effect is not necessarily. The ugly low-profile cars generally use the cheapest halogen lamps. The light-emitting principle is similar to that of a light bulb, except that halogen elements are added to the light bulb to extend its life. The brightness of this lamp is not high, equivalent to more than a thousand candles, and the same as a light bulb. Therefore, if the vehicle speed is fast, it will affect safety because the irradiation distance is too short.



The xenon lamp used in the middle and high-end cars is based on the principle of filling the quartz tube with high-pressure inert gas xenon, and then applying a high voltage of more than 20,000 volts. The light emitted is whiter and brighter than halogen lamps, and it has a longer life and consumes less power. However, the cost of xenon lamps is high, and they are generally used in middle and high-end cars. And the LED that sounds taller is actually the light-emitting diode on the radio. It is brighter than xenon headlights and has lower energy consumption, and it is not necessarily scrapped when the entire vehicle is scrapped.

Moreover, it is small in size and high in value, and can be shaped into any shape by designers. Of course, the price is also the most expensive. The most expensive all-LED headlights can only afford luxury cars. However, the most expensive is not necessarily the best. Because of the strong penetrating power of yellow light, halogen lamps are more reliable in rain and snow. Lighting effects can't just look at the light source, but also at tuning and other high-tech.
