The color temperature of xenon headlights affects lumens

Color temperature is a general indicator that represents the spectral quality of the light source. Generally expressed by Tc. The color temperature is defined by the absolute black body. When the radiation of the light source in the visible region is exactly the same as that of the absolute black body, the temperature of the black body at this time is called the color temperature of the light source.
Luminance is generally called brightness, a unit of luminous flux, and the ability to describe the intensity of the visual response generated by the light source radiation per unit time.
From the above definition of color temperature and lumen, there is no proportional relationship between color temperature and lumen. Color temperature and lumen are only two important indicators for measuring xenon lamps, so why do some people still mistake the color temperature of xenon lamps? The higher, the higher the lumens, the stronger the brightness?
I think the fundamental reason lies in the location. It’s like in a hot summer, there are two people, one outdoors and one indoors. The indoor people think that the sun outside is very good, and they can take pictures of the scenery in the distance. It is clear that people outside can’t open their eyes because the sunlight is too violent, and they can’t see the surrounding environment. This is also the case during night driving. In the car, you may think that the outside road conditions can be clearly seen after turning on the xenon headlights, but the driver or pedestrian on the roadside is stunned by your xenon headlights. I can’t open my eyes. So many people think that the higher the color temperature of the xenon headlights, the higher the brightness of the lights, because the location is outside the car, if inside the car, in fact, the higher the color temperature, the lower the lumens. Of a situation.
We can illustrate with some data. The color temperature of European xenon headlights is required to be controlled at 4300K, and its lumen is 3200lm; the color temperature is 6000K, the lumen is 2600lm; the color temperature is 10000K, the lumen is only 2000lm.
It can be seen from the data that the higher the color temperature, the lower the light lumens, and the poorer its penetration into fog and rain…So when car owners modify their lights, they still have to ensure their driving vision. It will not cause trouble to other people as the standard, comply with relevant modification laws, and carry out modifications reasonably.
