Color temperature is one unit of measure representing the inclusion of a color component in a light ray. Theoretically, blackbody temperature refers to the color that an absolute blackbody assumes after heating from absolute zero (-273 ℃). After being heated, the black body gradually turns from black to red, turns yellow and turns white, and finally emits blue light. When heated to a certain temperature, the spectral components contained in the light emitted by the black body are called the color temperature at this temperature, and the measurement unit is "K" (kelvin). If a light source emits light having the same spectral composition as the light emitted by a black body at a certain temperature, it is called a certain K color temperature. If the color of the light emitted by the 100W bulb is the same as that of the absolute blackbody at 2527 ℃, the color temperature of the light emitted by the bulb is: (2527+273) k=2800k.
