The color of the laboratory is different. Is there any difference between the morning sunlight and the afternoon sunlight? For printing and dyeing factories, choosing the source of light is a very important thing! Standard light source operating parameters The standard light source color-matched light box is usually a combination of multiple light sources. It helps users provide simulated sunlight D65, D50, simulated shop showroom lighting TL84, CWF, U30, and home lighting F, INCA, horizontal sunlight HORIZON, For ultraviolet lamps, UV, etc., the corresponding parameters of each light source are not the same. Light source name Color temperature(K) Tone RGB Explanation A 2856 Incandescent lamp/tungsten B 4874 Direct sunlight at noon C 6774 Average/North Sky Daylight D50 5003 Light on the horizon D55 5503 Morning/afternoon daylight D65 6504 Noon Sun: TV, sRGB color space D75 7504 North sky daylight E 5454 Equal energy F1 6430 Daylight Fluorescence F2 4230 Cool white fluorescence F3 3450 White fluorescence F4 2940 Warm white fluorescence F5 6350 Daylight Fluorescence F6 4150 Lite white fluorescent F7 6500 D65 simulator, daylight simulator F8 5000 D50 Simulator, Forest City F40 Design 50 F9 4150 Cool white luxury fluorescence F10 5000 Philips TL85,Ultralume 50 F11 4000 Philips TL84,Ultralume 40 F12 3000 Philips TL83,Ultralume 30 A light source: The color temperature is 2845K, which is equivalent to the light radiated by the incandescent lamp at 2800K. Light source B: The correlated color temperature is 4800K, which is equivalent to direct sunlight at noon. C light source: The correlated color temperature is 6700K, which is equivalent to the natural light during the day, and it has more blue components. D65 light source: The correlated color temperature is 6500K, which is equivalent to the average daylight. In recent years, it is often used as a standard light source for color TVs. E light source: also known as isoenergetic white light, that is, P(l)=constant. It is a hypothetical light source that does not actually exist. It is used purely to simplify calculations in chromatics, and its correlated color temperature is 5500K. F series illuminants represent various types of fluorescent lighting. Different color temperature, different light color Color temperature Light color Feel <3000K Warm (reddish white) Steady and warm 3000-5000K Middle (white) Readily >5000K Cool type (white with blue) Cold The color is usually observed in daylight, so the fine color discrimination in industrial production requires that the lighting source must have a spectral power distribution that approximates real daylight, that is, the D65 standard light source specified by CIE, and the D65 standard light source light box is also a large market demand.
