A car is assembled from many parts. The lights are both the eyes and the language of the car. They can help us illuminate the road ahead and also allow car owners to communicate with each other, so the lights of a car are very important. , are used when taking the driver's license test. If you don't understand it, it will be difficult to pass the test.
In the early days, due to technical reasons, many cars had halogen light sources. Now that technology has improved, LED light sources have become popular. However, low-end models are still halogen. Some young people will spend their own money to modify them after buying them, and most of them will be changed to xenon. Headlights. In fact, halogen headlights are very cost-effective, very practical, and have many benefits. So how do you change the headlights? The advantages and disadvantages of xenon lamps, halogen lamps and LED lamps will be explained today.
The first is LED. I have to say that this kind of light source has many benefits, but it has also been over-promoted by companies. Because it is used in high-end models, it is too mythical. It is really not as magical as people say. In fact, LED is The abbreviation of the English name means light-emitting diode.
At first, the usage environment was relatively simple, and it was used as various signboards or as circuit indicator lights. It has only become popular in cars in recent years. However, the light set gives people the impression that the brightness is very high, even equivalent to natural light during the day. It also has a long service life and saves electricity, so only high-end cars have LEDs. With LEDs, cars are more aggressive when driving.
Generally, the service life of LED car lights can reach 50,000 hours, and this kind of light group has more concentrated light points and better brightness effect. However, it also has many shortcomings. Because the temperature is too high, some quality materials will often age faster. There is a risk of spontaneous combustion. Although the cost of the lamp set is getting lower and lower, in order to highlight the selling point, it is rarely used on low-end models.
Xenon headlights are a favorite among many people when they are refitting. The light sets consume less power and are of high quality. Before LEDs became popular, xenon headlights were popular all over the country. The light is softer and not dazzling when turned on. The effect is better than halogen lights, but the cost is a bit high, and it only appears on high-end models. Xenon headlights require additional lenses to work, otherwise they will scatter and affect the vision of other vehicles, so xenon headlights The shortcomings were replaced by LEDs.
Halogen headlights have many advantages, including low cost. Like ordinary incandescent lamps, the tungsten filament is powered to emit light, which converts electrical energy into heat energy and then into light energy. This kind of light source is now commonly used in cars. The price is low and the practicality is good. This kind of light is better to use in foggy weather because it has strong penetrating power. However, the disadvantage is that it is not high-grade and young people do not like it very much.
