Advantages of LED Automobile Headlights

2022-12-28 11:27:38

At present, the automobile headlights that are still in practical application mainly include halogen lamps, xenon lamps, and emerging LED lamps. Among them, halogen lamp has the disadvantages of low luminous efficiency and large heat generation, and their brightness is relatively low. It is generally the low configuration standard configuration of cars, so it is difficult to meet the needs of current drivers. On the other hand, the service life of halogen lamps is relatively short. Under normal circumstances, the service life of a halogen bulb can last about 1000 hours at most. In addition, the appearance of halogen lamps is rigid and can only be made into double round lamps, which limits the lamp shape.




The xenon lamp with higher brightness is the mainstream headlamp used by the current high-end vehicles. However, the xenon lamp has poor focusing performance, and because it is too bright, it is easy to shake the driver of the opposite vehicle, causing an accident, and its light penetration is poor. In foggy and snowy weather, the penetration of the xenon lamp is very weak. Another fatal defect is that the xenon lamp has a delay effect. This is because of the working principle of the xenon headlamp. It takes 2-4 seconds to light it. When the vehicle is driving at high speed, the horn is often useless, so you need to use the headlamp to "shake" the vehicle in front of you, but if you rely on the xenon headlamp, it will not be urgent.




Emerging LED lamps have the advantage of very high luminous efficiency. LED lights convert electric energy into light energy directly through LED, so LED lights are also called cold light sources. The working temperature is generally 50 to 70 ℃, and the power consumption is only about 1/10 of that of ordinary car bulbs. So it can better save fuel consumption and protect the car circuit from being burned out by excessive load current. In addition, LED is similar to xenon lamps in brightness, and its energy-saving performance is stable and environmentally friendly.


There are no ultraviolet and infrared rays in its light spectrum, and the headlights are combined with multiple LEDs. Therefore, the shape can be matched at will and can be shaped into a cool shape, which is very beautiful. In addition, its service life is very long, can reach 50,000 hours, and has a wide color temperature space. It can be realized from high color temperatures to fog lamps. Its high-speed reaction speed makes it on point without delay, becoming the most potential automotive headlamp technology at present.
