Recently, GM announced that its external light source of Cadillac ELR uses LED, which will be the world's first electric vehicle that uses LED as its light source.
The use of LEDs on cars has long been a news, but this time Cadillac ELR will use LEDs for external lighting, including the main source of headlights. Although the new Mercedes-Benz S-Class, which has just been listed abroad, uses LEDs almost all of its cars, it is still the first time in electric vehicles, and it is more in line with the energy-saving and environmental protection direction that electric vehicles admire.
LED has the characteristics of long life, high brightness, low energy consumption and fast time. Therefore, it is very worthy to promote a large number of applications in the car, and the whole visual effect is very dazzling. Although at present, there are still some shortcomings in LED itself, such as color temperature and color rendering index. But LEDs can rely on technology to combine more lenses and filter mates, as well as a variety of ways to improve LED energy consumption to make it more suitable for use as road lighting.
