The color matching light box provides a standard light source for people to simulate various environments when visually detecting the color deviation of articles, such as simulating sunlight, simulating the lighting of shop showrooms, and household lighting, horizontal sunlight, ultraviolet lighting, etc. Specifications: Configuration: six light sources: D65, TL84, CWF, F, UV and TL83. Weight: 35Kg. Volume (width x depth x height): 7 10x530x570 mm. Standard light source color matching light boxes are widely used in textiles, printing and dyeing, printing, plastics, pigments, paints, inks, photography and other colors. No matter how to prepare color introduction or design or choose product color, Huiyuan standard multi-light source light box can provide you with a fair and objective color matching environment. The advantage of multi-light source switching makes it easier for you to detect whether there is metamerism between samples. This phenomenon means that the color of the sample matches one light source, but it does not match when switching to another light source. Add ultraviolet light waves to make the color matching light box provide you with the closest natural sunshine effect. The ultraviolet wave part can be used alone or combined with other light sources to detect fluorescent whitening agents on products, dyes and coatings more effectively.

The names of common light sources with complete configuration in British and American standards can be changed. It is more convenient to add a light source. Description of light source: D65 international standard artificial daylight color temperature: 6500K power: 18W TL84 Europe, Japan and China store color temperature: 4000K power: 18W CWF American cool white shop light source. Color temperature: 4 150K power: 20W F family hotel lamp and colorimetric reference light source Color temperature: 2700K power: 40W ultraviolet light source wavelength: 365nm power: 20WL83 European standard warm white shop light source (warm white). Color temperature: 3000K Power: 18W Working principle Let's start with a simple life case. When we go to the store to buy clothes, we often think that the color of a dress is beautiful because of the special lighting of the store lights, but when we go out for a walk or go home in it, it will greatly reduce the aesthetic feeling when we buy clothes in the store, and even think that the colors don't match and we don't want to wear them anymore. This is because the color of the same object is different for human eyes under different lighting sources, which is the so-called metamerism effect.
For some demanding goods, especially export products, inspectors also have high requirements for color. One of the important indicators is to check the color difference of goods under the standard light source specified by the merchant, such as the color difference between goods and samples, the color difference between the thread of clothing and the cloth, the color difference between the keys of the telephone handle and the shell, the color detection of printed paper products, and the color requirements of paint ink. These are inseparable from the standard light source color matching light box.
Color-matching light boxes are usually a combination of various light sources, for example, they can provide simulated sunlight D65, D75, D50, simulated store exhibition hall lights TL84, CWF, U30, as well as household lights F, INCA, horizontal sunlight horizon, ultraviolet light UV and so on. These light sources must be recognized by large international organizations, such as in-store lamps recognized by Wal-Mart and Martha, daylight recognized by international testing institutions, and lamps with various special requirements specified by merchants.
