Xenon headlight color temperature affects the brightness
Color temperature is the most common indicator of the spectral quality of a light source. Generally expressed as Tc. The color temperature is defined in terms of an absolute black body. When the radiation of the light source is completely the same in the visible region and the absolute black body, the temperature of the black body is called the color temperature of the light source.
The popular point of lumen is the brightness, which is the unit of luminous flux. It is the ability to describe the visual response of the light source radiation per unit time.
From the above definition of color temperature and lumens, there is no direct relationship between color temperature and lumens. Color temperature and lumens are just two important indicators of measuring xenon lamps. Why do some people still mistakenly think that the color temperature of xenon lamp? The higher the level of brightness, the higher the brightness.
I think the fundamental reason lies in the location. It's like there are two people. One is outdoors, the other is indoors. The people in the room will feel that the sunshine outside is very good. You can take pictures of the distant scenery. It is clear that people outside can't look at the sun because the sun is too fierce and they can't see the surrounding environment. The same is true during the night driving process. In the car, you may think that after you open the xenon headlights, you can clearly follow the road conditions outside, but the driver or the pedestrian on the roadside is shaken by your xenon headlights. Do not open eyes. Therefore, many people think that the higher the color temperature of the xenon headlamps, the higher the brightness of the lamp. This is because the location is outside the car. In the car, in fact, the higher the color temperature, the lower the lumens. A condition.
We can explain this with some data. The color temperature of the European xenon headlamps is required to be controlled at 4300K, with a lumen of 3200 lm; a lamp with a color temperature of 6000K, a lumen of 2600 lm, and a lamp with a color temperature of 10,000K, with a lumen of only 2000 lm.
From the data, it can be seen that the higher the color temperature, the lower the light's brightness, and the worse the penetrating power of fog and rain... so when the owners change the headlights, they still have to guarantee their own vision. It will not cause confusion to other people as a standard, comply with relevant modification laws, and reasonably perform modification.
