How to choose a Color temperature of the LED light?
- Aug 14, 2018 -

The color temperature of the LED is expressed by the absolute temperature K. When a standard black body is heated, when the temperature rises to a certain extent, the color begins to change gradually from deep red-light red-orange-white-blue-blue. When a light source and the black body have the same color, The source of the absolute temperature of the black body at that time.



Related principle

Since the correlated color temperature is actually the black body radiation approaching the light source color, the evaluation value of the light source color performance is not an accurate color contrast, so the two light sources with the same color temperature value may still be in the light color appearance. There are some differences. Color temperature alone cannot understand the color rendering ability of the light source to the object, or how the color of the object is reproduced under the light source.

Correlated color temperatures for different light source environments.

Color temperature change editing

The color temperature of the light source is different, and the light color is different:

The color temperature is below 3300K, the light color is reddish to give a warm feeling; there is a steady atmosphere and a warm feeling;

The color temperature is in the middle of 3000--6000K. There is no obvious visual psychological effect in this color tone, and there is a refreshing feeling; so it is called "neutral" color temperature;

The color temperature is over 6000K, and the light color is blue, giving people a feeling of coldness.

a. Color temperature and brightness Under the illumination of high color temperature light source, if the brightness is not high, it will give people a kind of yin atmosphere; under low color temperature light source, the brightness will be too high, which will give people a feeling of sultry heat.

b. Comparison of light color In the same space, two kinds of light sources with large color difference are used, and the contrast will have a layer effect. When the light color contrast is large, the level of light color can be obtained while obtaining the brightness level.

Irradiation with a low color temperature source makes the red color vivid;

Irradiation with a medium color temperature source to make the blue have a cool feeling;

Irradiation with a high color temperature source gives the object a cold feel.
