Now LED applications can be said to be very wide in the car, such as LED daytime running lights, width lights, angel eyes, etc., and even now have LED headlights. In some high-end cars, LED headlights have replaced xenon lamps and are favored by manufacturers such as BMW and Audi. It can be seen that the opportunities for LED headlights in the automotive market are great, but with the advent of opportunities, the challenges are gradually emerging, so we now analyze the development prospects and challenges for the application of LED headlights in automobiles. . Challenges: Although the advantages of LED headlights are great, they can't cover up some of the flaws in their existence, such as light radiation problems and expensive maintenance costs. Optical radiation is an urgent problem to be solved in current LED products. In the application of actual LED headlights, the potential photobiological radiation hazards of LEDs, such as blue light, should also be considered, which will have a certain impact on the human cornea. Depending on the application, LEDs can also have a health impact on people due to flicker and some long-term photobiological effects. This may not be a big problem for in-car reading lights, but the user experience will be more and more demanding, not only to meet the requirements of the experience, but also to be safe and radiation-free. Expensive maintenance costs are the reason why many owners are discouraged from LED headlights. Although the LED has a long service life, when there is no accident at that time, if the LED headlights fail, the cost of the repair is not fixed. For example, if the LED of the LED turn signal is burned out, then it is not a simple matter of changing a light bulb during maintenance. It is necessary to replace the entire assembly to be repaired. This has led many car owners to think that LED headlights are too difficult to serve, so they prefer to choose xenon or halogen lamps. Opportunity articles: LEDs have many advantages in automotive applications, such as energy saving and long service life. For example, LED daytime running lights not only consume 1/20 of the halogen lamp, but also have a long life. If the product is of good quality, the service life can reach 100,000 hours. It can be said that if there is no accident, how long does your car have? Long, LED daytime running lights can also be used for long. Because the advantages in actual use are quite prominent, this is the biggest opportunity for LED headlights so far. There are also other opportunities, such as the shape, the LED makes the shape and line of the headlights richer, and the night recognition is higher. For example, the angel eye and the devil eye are very popular among the enthusiasts. In terms of durability, because the LED components are simple, the impact resistance and shock resistance are very good, so they can adapt well to different environments; the response speed is fast, LED lighting only needs microsecond level, it can be quickly illuminated on taillights and turn signals to achieve better warning effect. It is used on headlights and has higher response speed than xenon lamps and halogen headlights. Driving safety has a better guarantee. By analyzing the opportunities and challenges of LED headlights in the car, it is not difficult to see that the opportunity is far greater than the challenge. Nowadays, it is a society that pays attention to energy conservation and environmental protection. No matter what it is, as long as it is low-carbon and energy-saving, it can attract the attention of many people. It is precisely because of this reason that LED has developed so rapidly. As for the technical problems, with the development of science and technology, it will certainly be solved one by one.
