Visual color preference oriented exhibition illumination light quality evaluation method

Abstract

The invention discloses a visual color preference oriented exhibition illumination light quality evaluation method. Human eye vision preference perception oriented light source color rendering quantitative characterization can be realized effectively. The method comprises the following steps: determining an exhibition illumination mode, wherein exhibition illumination conditions are concluded intothree types of showcase observation, open type observation and general type observation; measuring light source relative spectral power distribution information in a visible light range, and calculating a corresponding light source color rendering index according to the determined exhibition illumination mode; and according to the determined exhibition illumination mode, calculating light sourcecolor rendering quantization comprehensive evaluation index under different exhibition conditions in combination with corresponding existing light source color quality index so as to complete visual color preference oriented light quality evaluation.

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
