Embodiment Construction

[0043] In conjunction with the accompanying drawings, the specific description of the embodiments of the present invention is provided as follows.

[0044] Such as figure 1 The embodiment shown provides a color rendering-oriented technical scheme for color rendering evaluation of display light sources. Based on hue chess samples and combining the color characteristics of objects to be displayed, the color discrimination error estimation model is used as a means to realize the identification of light source illumination. The characterization of the color power performance provides an accurate and targeted evaluation method for the color recognition power of LED lighting in the field.

[0045] The embodiment uses 5 kinds of LED light sources with the same color temperature (5500K) and different Duv characteristics as the light sources to be evaluated, and 7 blue jeans with gradual changes in color as the objects to be displayed, and the results of the FM100 color discrimination ...

Abstract

The invention discloses a color discrimination-oriented display light source color rendering evaluation method and a color discrimination-oriented display light source color rendering evaluation system. The color discrimination-oriented display light source color rendering evaluation method comprises the steps of: acquiring spectral power distribution of a target light source; acquiring a spectralreflectivity of an FM100 hue chess; acquiring a spectral reflectivity of a to-be-displayed object; calculating chromaticity information of color samples of the hue chess and chromaticity informationof the to-be-displayed object in a uniform color space; selecting corresponding hue chess samples according to the chromaticity information of the to-be-displayed object, and calculating a hue angle difference value between the samples; for a light source to be evaluated, obtaining a corresponding estimated value by combining a color discrimination error estimation model according to the hue angledifference value of the selected hue chess samples, and realizing representation of the color discrimination performance of light source illumination. The color discrimination-oriented display lightsource color rendering evaluation method realizes efficient and accurate representation of the color discrimination performance of the light source illumination, and further provides an accurate and targeted LED illumination color discrimination evaluation method in the field.

Description

technical field [0001] The invention belongs to the technical field of LED intelligent lighting, and in particular relates to a method and system for evaluating the color rendering of display light sources oriented to color discrimination. Background technique [0002] As the fourth-generation lighting source, LED light source has the characteristics of high luminous efficiency, convenient packaging, energy saving and environmental protection, and has been widely used in the field of lighting. At present, with the advancement of lighting technology, the status of LED light sources in the commercial and civil fields continues to increase. The multidimensionality of lighting quality evaluation has been generally recognized by the industry and academia, that is, when evaluating the lighting quality of light sources, it should include lighting. Fidelity, harmony, color recognition, naturalness and other dimensions. [0003] Among them, because accurate identification of differe...
