Color temperature Refers to the numerical value of the color of light expressed in terms of the temperature of a black body (theoretically a virtual object that completely absorbs outside light). The unit is K (Kelvin).
The wavelength distribution of black light (hue) varies with temperature. In general, when the color temperature is low, it looks red, and the color temperature is high when it is green. The wavelength distribution of black light (hue) varies with temperature. Color temperature is often used to indicate the light color of fluorescent lamps and white LEDs, and the whiteness of the display.
Taking a white LED as an example, a common type of blue LED chips and yellow phosphors (average color rendering index Ra of 70 or more) is mostly a daylight color with a color temperature of 6000K or more, and a color of a light bulb such as a red LED The color temperature more than 3000K. Improving the light color of the phosphor combined with the blue LED chip, and obtaining the color temperature above 4000K and above 5000K. The color temperature can be used separately according to the setting place of the utensil.
For example, the office is best set with the sun close to the higher color temperature lighting, and most families and restaurants prefer to use and incandescent lamp close, low color temperature lighting.
