The standard light source color comparison box is a lighting box that simulates a variety of ambient lights. It is mainly used to detect the color of goods. It is widely used in textiles, printing and dyeing, printing, plastics, pigments, paints, inks, photography and other fields involving color. It is used for visual evaluation of color fastness of materials in textile, automobile and other industries, color matching proofing, identification of color difference and fluorescent substances, etc., so that samples, production, quality inspection, and acceptance are carried out under the same standard light source, and the color deviation of goods can be accurately checked. Ensure that the quality of the color of the goods meets the requirements.
This article mainly analyzes the calibration method of the illuminance and correlated color temperature of the standard light box, as follows:
1. Calibration equipment: Illuminance Meter: The illuminance measurement range is 0.1~999 90 lx, the accuracy level is Class I; the color temperature measurement range is 2 300~20 000 K, and the accuracy level is ±100 K.
2. Calibration process
