Although LED daytime running lights have poor penetration, many car manufacturers (or light factories, such as Marelli) have already come up with solutions. Many models already have detectors on them, which can monitor the moving objects and light sources in front of them, so as to control the light source and angle of the lights, so as to increase the recognition of the traffic without affecting the safety of others.
When driving at night, under normal circumstances, the matrix LED headlights illuminate the front with high-beam lights. Once the system light source sensor detects that the emitted light beam is on the opposite side or the vehicle in front, it will automatically adjust or turn off the number in the light group It is a single LED, so that the vehicles in front will not be affected by the dazzling high-brightness LED. The front car can clearly know where you are, and the function of the front fog light is replaced.
In addition, there is also laser taillight technology. Take Audi as an example. Although the fog lamp has a strong penetrating ability, in extreme weather conditions, the beam of the fog lamp may still be affected by the haze and weaken the beam penetration. Penetrating ability.
The laser rear fog lamp uses the characteristic of directional light emission of the laser beam to improve this problem. The laser beam emitted by the laser fog lamp shines obliquely downward toward the ground in a fan shape, which not only plays a role of prompting the rear vehicle, but also avoids the influence of the beam on the rear driver.
