Colour temperature is a measurement unit for indicating to include in light color component.Theoretically, colour temperature refers to absolutely black
The color that body is presented after being heated since absolute zero (- 273 DEG C).Black matrix after heated is gradually red by blacking, turns Huang, hair
In vain, blue light is finally sent out.It is known as this temperature when being heated to the spectral component contained by the light that certain temperature black matrixes are sent out
The lower colour temperature of degree, measurement unit for " K " (Kelvin) if, the light that sends out of a certain light source, sent out with black matrix at a certain temperature
The identical of spectral component contained by light is known as certain K colour temperature, such as 100 W light bulbs send out the color of light, with absolute black body in 2527K
When color it is identical, then the colour temperature for the light that this light bulb is sent out is exactly：2527K+ 273K=2800K.
