What’ s the Color Temperature?
Color temperature is a physical quantity used in lighting optics to define the color of the light source. That is, a black body heated to a temperature, the light emitted by the color and the light emitted by a light source of the same color, the black body heating temperature is called the color temperature of the light source, referred to as color temperature. The unit is expressed in "K" (Kelvin temperature unit).
The Color temperature of LED light is the color when the LED lighting, it generally divided into: warm white (2700K-3000K), Natural white (4000K-5000K) & cool white (5500K-6500K)
How to choose the Automotive LED light?
The color temperature only represents the spectral component of the light source and does not indicate the luminous intensity. But the color temperature directly affect the brightness and contrast. At the same time, the level of color temperature and the human eye on the light color feel great relationship. Here we compare the different color temperature lamp effect.
3500K halogen headlight color temperature is the lowest, light yellow, for night driving, not only the brightness is not enough, and increase the driver's fatigue, is not conducive to safe driving at night. The middle is 5500K LED headlamps, is natural white, you can reach the safe range of driving at night, and the human eye looks more comfortable. 7000K xenon headlamps, bright white light with blue light, the irradiation range has improved, but the penetration is very poor.
Considering the brightness and penetration and other factors, recommend the use of color temperature between 5500K-6500K LED lights, both to meet the needs of night driving lighting and do not need to worry about the penetration problem in the rainy or foggy day driving.
