80% of people don't know why your car doesn't have front fog lights?
Consulted the configuration of mainstream car brands on the market, found a strange phenomenon, the front fog lights gradually disappear!
In everyone's mind, fog lights are a safety configuration, which is not equipped with a high one. In many automobile evaluation videos, when talking about the absence of front fog lights, the host must have said: We strongly suggest the manufacturer not to reduce the matching!
But the truth is... Found that today's cars, low equipped with front fog lights, high equipped without front fog lights......
So now there are two situations: one is that there is no front fog lights installed or daytime running lights; the other is that other light sources replace independent front fog lights or are integrated in the headlight assembly.
And that light source is daytime running lights.
Many people think that daytime running lights just look cooler configuration, in fact, this daytime running lights have been used for a long time in foreign countries, so that when the fog, their cars are easier to be found by the front car. Daytime running light is not a light source, just a signal light, which is like the function of the front fog light.
However, there is still a problem with daytime running lights replacing front fog lights, that is, the penetration. Needless to say, the penetration of traditional fog lights is better than that of daytime running lights. The color temperature of car front fog lights is about 3000K, and the color is yellowish and has strong penetration. And HID, LED lamp color temperature from 4200K to more than 8000K; The higher the color temperature of the lamp, the worse the penetration of fog and rain. Therefore, if you pay attention to driving safety, it is best to buy daytime running lights + front fog lights models.
The traditional fog lights will disappear in the future
Although the penetration of LED daytime running lights is poor, many car manufacturers (or light manufacturers, such as Marelli) have come up with a solution. Many models have detectors, which can monitor the moving objects and light sources in front of them, so as to control the light source and Angle of the headlight, so as to increase the driving recognition degree at the same time, without affecting others' driving safety.
When driving at night, normally, the matrix LED headlamp will illuminate the front with the high beam. Once the system light source sensor detects that the beam is coming to the vehicle opposite or in front, it will automatically adjust or turn off several LED monomer in the light group, so that the vehicle in front will not be affected by the harsh high brightness LED. The car in front knows exactly where you are, and the fog lights are replaced.
In addition, there is laser taillight technology. Taking Audi as an example, although fog lamps have strong penetration ability, fog light beam may still be affected by haze in extreme weather conditions, thus weakening the penetration ability of the beam.
The laser rear fog lamp improves this problem by using the characteristic of laser beam directional luminescence. The laser beam emitted by the laser fog lamp is fan-shaped and slanted down to the ground, which not only plays a warning role to the vehicle behind, but also avoids the influence of the beam on the driver behind.
