What's the color temperature of lamp come from？
Feb 25, 2022
Color temperature is a unit of measurement that expresses the color components contained in light. Theoretically speaking, the black body temperature refers to the color of an absolute black body when it is heated from absolute zero (-273°C). After being heated, the black body gradually changes from black to red, turns yellow, turns white, and finally emits blue light. When heated to a certain temperature, the spectral composition of the light emitted by the black body is called the color temperature at this temperature, and the unit of measurement is "K" (Kelvin).
If the light emitted by a light source has the same spectral components as the light emitted by a black body at a certain temperature, it is called a K color temperature. For example, the color of the light emitted by a 100W bulb is the same as the color of an absolute black body at 2527°C, then the color temperature of the light emitted by this bulb is: (2527+273)K=2800K
Used in the LED industry, generally speaking, 2700K is warm light, 4000K is natural light, and 6500K is cold light. The choice is made according to the requirements of people in different regions, which plays the role of lighting and adjusting the environment, according to different actual needs and application scenarios. , LED lights have a variety of options.
