Introduction to the names of the color temperatures of different light sources

What is the international standard light source colorimetric light box? International standard light source colorimetric light box is a colorimetric light box inside the standard lamp is in line with international standards of lamps, each light source color temperature, illuminance, apparent finger are in line with international standards, installed in the colorimetric light box box inside the body, so that the colorimetric light box to achieve a standard environment in line with international standards. 

Standard light source that is specified by the CIE radiation similar to the CIE standard illuminant artificial light source, the standard illuminant is the illuminant with a certain moment of the day light the same or approximately the same relative spectral power distribution, the color of the object is light irradiated on the surface of the object after the presentation of the spectral reflections of the same object in the different light source irradiation, due to the degree of difference in the degree of absorption of different wavelengths of light, so that the object presents a different color. is different. 

Standard light sources are mainly of the following types:

F--Home hotel light Color temperature: 2700K Power: 40W

A--American kitchen window spotlight Color temperature: 2856K Power: 60W

UV - ultraviolet light source (Ultra-Violet) Wavelength: 365nm Power: 20W

D65 - international standard artificial daylight (Artificial Daylight) color temperature: 6500K Power: 18W

D75--Simulation of northern average sunlight Color temperature: 7500K

D50 - simulated sunlight color temperature: 5000K

U30--American warm white store light source (Warm White Fluorescent) Color temperature: 3000K Power: 20W

U35 - U.S.retailer Target-Target designated color lamps color temperature 3500k 

TL84--Europe, Japan, China store light color temperature: 4000K Power: 18W 

CWF - the United States Cool White Fluorescent store light source (Cool White Fluorescent) Color temperature: 4150K Power: 20W 

TL83 -- European standard warm white store light source (Warm White ) color temperature: 3000K power: 18W
