For most friends who like cars, lights are a very interesting topic. Whether it is the “candlelight” of your own car, the “high-light dog” that everyone shouts on the road, or the high-end models that can identify their identity hundreds of meters away, the headlights of the vehicle will always be the most on the front face. The attractive part. This truth has been deeply implanted in our hearts after many years of practice in the “German Troika”. For Chinese brands, it is now a small step. Great progress has been made in appearance design, and naturally there are many dazzling headlight designs, such as the upcoming Mustang T80, which will soon become the first Chinese brand SUV to adopt all-LED headlights.
At present, the main light sources of car headlights are halogen, xenon and LED. Halogen headlights are the most common. More than 60% of new cars on the market now use halogen headlights. The advantages are low manufacturing and maintenance costs and easy replacement. The disadvantages are also obvious and the brightness is not enough. As a former “advanced product”, xenon headlights have been all the rage for a long time. Its high brightness and long irradiation distance are its biggest advantages. It was once regarded as a necessary configuration by car owners.
However, as a transitional product, xenon headlights also have obvious disadvantages: problems such as delayed start-up and strong current shock at the instant of start-up have always plagued car owners. At the same time, the penetration effect of xenon headlights in rain and fog weather is not ideal, especially in foggy weather, the driver’s eyes are basically white.
With the development of industrial technology, LED lighting has gradually become the future trend. Nowadays, in the field of home lighting, LED lighting has become the mainstream. The reason is very simple. The LED light source uses less power in exchange for better brightness. Better lighting effects reduce energy consumption and have a longer lifespan.
In the field of automotive lighting, LED headlights are still “high-end” products, which are more common in some luxury brand models. Generally, cars with less than 200,000 yuan are rarely equipped with LED headlights. Even if they are, they are basically top-mounted. The models will be equipped, and not all LED headlights, only the common low-beam headlights will be replaced by LED light sources. If you look down again, in the range of 150,000 yuan, there is almost no vehicle using LED headlights. Imported cars with high tax rates need not be self-explanatory, whether it is a joint venture model or a Chinese brand model that has always been configured to win It is also difficult to find one. But this time, the Mustang T80 broke this situation.
Well, when it comes to LED headlights for cars, you have to mention the famous “light factory”-Audi. In 2008, Audi first used LED daytime running lights on the A4, which first opened the automotive LED era. After that, many manufacturers started to follow up and adopted LED daytime running lights. European legislation stipulates that in order to drive safely, all models on sale must be equipped with LED daytime running lights. However, for a period of time, all manufacturers only stayed in the step of LED daytime running lights. It was not until the launch of the Audi A8 and the second-generation Mercedes-Benz CLS in 2010 that the real LED headlights appeared in people’s sight.
At that time, the Audi A8 was amazed once with a pair of matrix-type all-LED headlights. Not only did it have a stronger sense of presence than Mercedes-Benz CLS, but it also won the name of “Light Factory” for Audi. The matrix full LED headlights of the Audi A8 are composed of LED lamp beads, laser rangefinders and brightness sensors. During driving at night, the matrix LED headlights will always be illuminated with high beams. Once the light source sensor detects When an oncoming vehicle is detected, it will automatically adjust or turn off several LED lamp beads in the light group, so that the vehicle in front will not be interfered by strong light, ensuring driving safety.
