What Is Color Temperature
- Apr 18, 2018 -

Color temperature is a physical quantity used to define the color of light source in illumination optics. When a black body is heated to a temperature, the color of the emitted light is the same as the color of the light emitted by a light source. The temperature of the blackbody is called the color temperature of the light source, for short. The unit is represented by "K" (Kelvin temperature unit).——Color temperature


Color temperature  is an important application of visible light in photography, video, publishing and other fields. The temperature of the light is by comparing the color and thermal theory to determine the blackbody radiator. The Kelvin temperature of the thermal blackbody radiator matching with the color of the light source is the color temperature of the light source, which is directly related to Planck's blackbody radiation law.——Color temperature

Color temperature is the most universal index to indicate the spectral quality of light source. It is generally expressed in Tc. The color temperature is defined by absolute blackbody. The radiation of absolute blackbody and the radiation of the light source are exactly the same in the visible region, at this time the temperature of the black body is called the color temperature of the light source. The characteristics of the low color temperature light source are the energy distribution, the red radiation is relatively more, usually called "warm light". After the color temperature increases, the proportion of blue radiation increases in the energy distribution, usually called "cold light". The color temperature of some common light sources is: Standard candlelight 1930K (Kelvin temperature unit); tungsten filament lamp for 2760-2900K; fluorescent lamp for 6400K; flash for 3800K; noon sun for 5000K; electronic flash 6000K; blue sky for 10000K.——Color temperature

Light yellow with low color temperature, such as incandescent lamp, 2800K, high temperature and light blue, such as purple light, 9000K or above. It is generally believed that the standard white light and color temperature is 6500K and the white light emitted by CRT is about 5500K. So a little change of the mixture ratio of three colors can be used to simulate the effect of increasing the color temperature. The process of the change of photography, camera, display and other equipment, which is realized by the principle of color temperature, is called the color temperature effect.——Color temperature
