A method for evaluating the quality of exhibition lighting based on visual color preferences

Abstract

A method for evaluating the quality of exhibition lighting oriented to visual color preferences can effectively realize the quantitative characterization of the color rendering of light sources oriented to the perception of human visual preferences, including determining the lighting mode of exhibitions and summarizing the lighting conditions of exhibitions into the observation and opening of display cabinets. There are three types of observations: conventional observation and general-purpose observation; measure the relative spectral power distribution information of light sources in the visible light range, and calculate the color rendering index of the corresponding light source according to the determined exhibition lighting method; combine the corresponding existing light sources according to the determined exhibition lighting method The color quality index calculates the quantitative comprehensive evaluation index of light source color rendering under different display conditions, and completes the light quality evaluation for visual color preferences.

Description

technical field [0001] The invention belongs to the technical field of light quality evaluation of exhibition light sources, and in particular relates to a method for evaluating the light quality of exhibition lighting oriented to visual color preference. Background technique [0002] Exhibition lighting plays an important role in lighting industry applications, including museum lighting, art gallery lighting, shopping mall lighting and many other applications. In exhibition lighting, the color information of exhibit objects under different light sources is an important dimension to evaluate the quality of exhibition light sources. In recent years, with the development of semiconductor lighting technology, the industry and academia have generally agreed with the multi-dimensional view of lighting quality evaluation, that is, evaluating the lighting quality of light sources should include color reproduction, preference, color discrimination, naturalness, etc. multiple dimens...

Problems solved by technology

[0011] In response to the above problems, some scholars believe that one-dimensional evaluation indicators cannot comprehensively characterize the color rendering of light sources (for example, visual color preference), so they propose a method of constructing a comprehensive index by combining multiple one-dimensional indicators in order to realize the color rendering of light sources. Improvement of quality evaluation accuracy

However, restricted by subjective and objective factors such as the level of theoretical methods, the above work is limited to the index construction stage based on specific color scientific theories and assumptions

So far, no research has reported on the validity of comprehensive indicators in a large number of psychophysical experimental cases
