The color temperature is the most common indicator of the spectral quality of the light source. The color temperature is defined by the absolute black body. When the radiation of the light source is exactly 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.
Due to the difference in color temperature, the color of light is also different. For example, when the color temperature is 4300K, the color of light is yellow with white; when the color temperature is 6000K, the color is white and close to natural light; when the color temperature is 10000K, light The color is light blue, which shows that as the color temperature gradually increases, the color of the light is gradually biased toward the cool color, which is often said cold light.
The color temperature of the halogen lamp is 3000K, the color is yellow, and the color temperature of the xenon lamp is 4300K ​​or more, and as the color temperature increases, the color gradually turns blue or even pink. Having said that, maybe you will feel a little confused, but you just have to remember that the color temperature is not a unit of brightness, which means that the color temperature has nothing to do with brightness.
If the color temperature is too high, it will be bluish (higher will appear purple). This color temperature light has very poor penetrating power in the foggy weather, so the situation is that you can't see the outside road in the car. The opposite driver or pedestrian is blinded by your eyes, which is very easy to create safety problems, so when choosing a xenon lamp, never choose to make your car look more cool, regardless of the modification law, choose the color temperature is too high. The product is not only for your own safety, but also for the safety of others.
Car led headlight color temperature selectionShould the lights be the brightest? Xiaobian tells you: not exactly. Bright blue light can not only improve the lighting effect for you, but also may lead to unnecessary traffic accidents. This is because the light produced by different light sources has different color temperatures.
As many car owners pay more and more attention to driving safety, most car owners choose to upgrade LED headlights instead of halogen headlights, because LED headlights have high brightness, long life, super energy saving and more stability, which makes LED cars big. The lamp becomes a replacement for halogen headlights. If you are considering color temperature to optimize your headlights, here's what you need to know.
What is the color temperature?
To understand why color temperature is very important, you must first understand what it is.
The color temperature, that is, when a black body is heated to a temperature, and the color of the light emitted is the same as the color of the light emitted by a certain light source, the temperature at which the black body is heated is referred to as the color temperature of the light source, referred to as the color temperature. Its unit is "K" (Kelvin).
Color temperature is the most common indicator of the spectral quality of the source. Technically, we use color temperature (K) to represent the color quality of the light source. For the color temperature and the color quality of the light source, it can be considered that the higher the color temperature, the colder the light, the lower the color temperature, and the warmer the light.
Different color temperatures correspond to different colors of light as shown above
3000K yellow light
4300K ​​white with yellow,
5500K light white, European standard car light maximum color temperature
Daytime under 6500K sunlight
7000-8000K white with obvious blue
8000K or more blue light
How to choose the color temperature of the car?The color temperature only represents the spectral composition of the light source, not the luminous intensity. However, the color temperature directly affects the brightness and contrast. At the same time, the color temperature has a great relationship with the human eye's perception of light color. Let's compare the effects of different color temperature lights.
The 3500K halogen headlight has the lowest color temperature and yellowish light. For night driving, not only is the lighting brightness insufficient, but also increases the driver's fatigue, which is not conducive to safe driving at night. In the middle is a 5500K LED headlight, which is white, which can reach the safe range of driving at night, and the human eye looks obviously more comfortable. Xenon headlights of 7000K, bright blue light with obvious blue light, the range of illumination is improved, but the penetration is very poor.
Considering factors such as brightness and penetrating power, the speed-changing brothers recommend LED lights with a color temperature between 5500K and 6500K, which can meet the needs of night driving lighting and worry about the penetrating power of rain and fog.
So choosing the right color temperature for the lights is just as important as choosing the brand of the lights!
