Abstract

The invention provides a light colorimetric performance optimization method and system for multiple light color light sources. The method comprises steps that outgoing light spectrum radiation efficiency, scotopic vision spectrum radiation efficiency and non-vision spectrum radiation efficiency are calculated according to photopic vision, scotopic vision and non-vision spectrum sensitivity curves and the preset three light color light sources, and a corresponding contour diagram is determined; two-element function fitting of the contour diagram is carried out, and corresponding contour values of outgoing light spectrum radiation efficiency, scotopic vision spectrum radiation efficiency and non-vision spectrum radiation efficiency are calculated; contour diagram gradient change of various color gamut type colorimetric points are acquired according to the contour diagram and the contour values corresponding to light spectrum radiation efficiency; gradient values of the color gamut type colorimetric points are acquired according to contour diagram gradient change of the various color gamut type colorimetric points. The method is advantaged in that unified optimization of the multiple light color light sources is carried out, light and chroma performance change rules of the multiple light color light sources can be predicted, and energy saving can be realized to a maximum degree.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a method and an optimization system for optimizing the photochromaticity performance of a multi-color light source. Background technique [0002] With the development of intelligent lighting technology, multi-color light source, especially multi-color LED intelligent control technology has been greatly improved, and the corresponding optimization scheme has also been developed rapidly. At the same time, various photometric and chromatic properties of the light source have been optimized and improved. Photometry was established by Lambert in 1760, which defined the main optical photometric parameters such as luminous flux, luminous intensity, illuminance, brightness, etc., and used mathematics to clarify the relationship between them and several important laws of photometry, such as the law of superposition of illuminance, The law of distance square ratio, cosine law...
