When buying a car, many people pay more attention to the brand, power, appearance, interior, etc., but in fact there is another decisive factor that will determine whether many people buy this car or not. That is the headlights of this car. The headlights are the eyes of a car. Whether the materials of the headlights are good or not and whether they are well designed directly determine the appearance of the front face of the car.
In the past, all cars had halogen headlights, which are what everyone calls candle lights. They later developed into xenon headlights with lenses, and then developed into LED headlights. In the past two years, they have been upgraded to matrix headlights. Headlights and laser headlights. Many people are dazzled and don't know the difference between these lights. But many people think that LED lights must be better than halogen lights and xenon headlights because they sound more advanced.
However, in fact, from the perspective of use effect, LED headlights are the worst among these light sources. Although LED headlights are more energy-saving than ordinary halogen lights and xenon headlights, they generate less heat and have a higher amount of light. However, LED headlights have very poor penetration and poor color rendering. If you are driving on a slippery black asphalt road at night, turning on low beam and high beam will have the same effect as not turning on high beam.
Of course, this does not mean that all LED headlights are not good. I am simply referring to LED headlights with a reflective tile structure. However, many models on the market priced below 300,000 use this type of headlight. Reflective tile LED headlights. Whether it is low beam or high beam, the display effect is particularly poor at night. Firstly, the lighting distance is not far enough. Secondly, the astigmatism is very serious. If you turn on the low beam, others will think that you are turning on the high beam and it will flash. you.
The cost control of a car can also be indirectly seen from the structure and materials of a car's headlights. Honda is very famous for its cost control. Basically all Honda models have reflective tile-type LEDs, such as the Civic, Accord, CR-V, Odyssey, and even the most expensive Honda family, the Crown Road, all have reflective tile-type LEDs. The display effect of the headlights at night is really amazing. It’s hard to describe in one word.
In addition to Honda, many other models are also using this kind of reflective tile LED, after all, the cost is very low. For example, the Focus, Regal, Cadillac CT5, all Volvo models, mid- to low-end models of the Mercedes-Benz E-Class, and most modern models are basically made of this kind of cheap reflective tile LED. The display effect of the original light source at night is really good. Not so good, you have to drive with your eyes wide open at night.
There are also many LED light sources with a lens structure that use relatively low-cost materials. The display effect at night is much better than that of reflective tile headlights. They have stronger light concentration and longer illumination distance. Also further away. Basically all BMW models are equipped with lenses, Audi is basically the same, many Volkswagen models, and many Lincoln models are equipped with lens-type LED headlights or dual-lens LED headlights, which are original. The display effect at night is also pretty good. Moreover, this kind of headlight with lens looks more impressive.
As for the halogen headlights and xenon headlights used on older models in the past, they were not eliminated because they were lagging behind. Nowadays, many manufacturers only use LED for the sake of LED. Many competitors’ models have LED headlights. I can’t justify not using them, right? But in fact, the xenon headlights and halogen headlights with lenses on older models have very good display effects, strong light concentration, and much better penetration than LED light sources. The most important thing is that the color rendering of halogen headlights is very good at night, while the display performance of LED headlights is relatively poor. Even if the brightness is very high, some things cannot be seen clearly at night.
Nowadays, some new mid-to-high-end models will have matrix LED headlights. This kind of light source structure is much more advanced than ordinary LEDs. Of course, the cost is also higher, and it will only appear on some more expensive models. Cars like those that sell for nearly one million yuan will basically use pixel-level headlights or laser headlights. Such headlights have better display effects and are more intelligent, but ordinary consumers are not able to access them.
Lighting is very important for a car, especially when driving at night, which is directly related to driving safety. So when buying a car, don’t think that the car uses LED headlights, just think that it must be very high-end. LED headlights with reflective tiles are not as good as xenon headlights, so when buying a car now, you should try to choose that kind. LED headlights with lens. What structure of headlights do you use on your car? What do you think of the display effect of LED headlights now?
