What is the color temperature of car headlights
Color temperature is a common indicator of the spectral quality of a light source. Temperature K is the color temperature that gradually changes from red, orange, yellow, green, and blue when a standard black body (such as platinum) is heated. When the temperature rises to a certain level, indigo (blue-violet) ) And purple. Using this characteristic of light color change, when the light color of the light source is the same as the light color of the black body, we call the temperature of the black body at that time, because the color of the light source is the color temperature of the light source.
As the color temperature is different, the color of the light is also different. For example, when the color temperature is 4000K, the color of light is white, slightly yellow; when the color temperature is 6000K, the color is white, close to natural light; when the color temperature is 10000 K, the color of light is light blue. It can be seen that as the color temperature gradually increases, the color of the light gradually tilts toward the cool color, which is often referred to as cold light. Different color temperatures correspond to different colors. Different wavelengths give the human eye different color perception capabilities, from red, orange, yellow, green, blue, indigo (blue-violet), and purple. The sensitivity of the eye varies greatly with wavelength. .
Understand the basic knowledge of color temperature, so when we buy lamps, what is the appropriate color temperature? First, understand the application of color temperature in car headlights. The color temperature of halogen lamps is 2300k-7000k (usually 3000K), and the color is yellow; the color temperature of xenon lamps is 4200-8000k (usually 4300k), and the color is yellowish, and the color temperature of LED headlights is 3200k-15000k (usually 6000K), and the color is white. The color temperature is not an indicator to measure the brightness of the lamp, that is to say, the color temperature has nothing to do with the brightness. Below you can see the lighting effects of different color temperatures.
