The color temperature (colo (U) r temperature) is the scale of the light color of the light source, the unit K (Kelvin), in the field of photography, video, publishing and other important applications. The color temperature of the light source is determined by contrasting its color and the theory of the hot blackbody radiation body. The Kelvin temperature is the color temperature of the light source, which is directly associated with the Planck black Body Radiation law.

Color temperature is the most common indicator of spectral quality of light source. generally expressed in TC. Color temperature is defined in absolute black, light source radiation in the visible area and absolute black body radiation is exactly the same, at this time the blackbody temperature is called the light temperature. Low color temperature light source is characterized by energy distribution, red radiation relative to more, usually known as "warm Light", the increase in color temperature, energy distribution concentration, the proportion of blue radiation increased, usually known as "cold". Some common light source color temperature is: The standard candle is 1930K (Kelvin temperature unit), tungsten is 2760-2900k; fluorescent lamp is 3000K, flashlight is 3800K, noon sunshine is 5600K; electronic flash is 6000K; blue sky is 12000-18000k.

The light that is usually seen by the human eye is composed of the spectra of 7 kinds of shade. But some of the light is blue, some are red, and the color temperature is a method specifically used to measure and calculate the colour components of light, created by the British physicist Lode Kelvin in late 19th century, and he worked out a set of color temperature calculations, which are based on the wavelength emitted by a blackbody radiator.

Color temperature (colortemperature) is a performance indicator for high-end displays. When a light source glows, it produces a set of spectra, a temperature that is required to be reached when the same spectrum is produced with a pure black body, which is the temperature of the light source. Now 15 inches above the numerical control monitor must have the color temperature adjustment function, through this function (generally has 9300K, 6500K, 5000K three choice) may enable the display color to satisfy the high standard work request. Some of the high-end products also support the color temperature linear adjustment function.
