Problems solved by technology

Although the measurement method of color measuring instruments can minimize the influence of human factors and give reliable, objective and repeatable measurement and identification results, traditional color measuring instruments cannot measure color images, curved surfaces, etc. due to the limitations of the principle and structure of the instrument itself. or bumpy, mixed, unevenly colored, or irregularly colored surfaces

Abstract

The present invention discloses a standard light source color observation box which comprises a box body with an observation cavity formed inside. The top of the observation cavity is provided with a standard light source which comprises a halogen tungsten lamp whose lower part is provided with a light filtering device. The top of the observation cavity is provided with an LED lamp. The halogen tungsten lamp emits light to go through the light filtering device to be mixed with the light of the LED lamp, and the light energy provided by a narrow band LED light source occupies 20% of the total radiation energy. The compensated light source quality is lower than 0.2A level according to the metamerism index specified by a CIE standard D illuminant, the color test of a tested article is carried out by the compensated light, and the accuracy of a long time color testing result is ensured.

Description

technical field [0001] The invention relates to a detection structure, in particular to a standard light source color observation box. Background technique [0002] At present, the daylight source of the standard D lighting body used in the standard light source color observation box or light box has a variety of brands of fluorescent tubes and tungsten halogen lamps are used to pass through the filter to make the irradiated light simulate the D lighting body specified by the CIE standard. The relative spectral power distribution of the irradiating light source with a tungsten-halogen lamp passing through the filter can reach the grade A level of the metamerism index of the D illuminating body stipulated in the CIE standard, but due to the influence of the material and manufacturing process technology, its function has a great influence on the radiation of the light source. It is difficult for the relative spectral power distribution technical index of CIED standard illumina...
