Abstract

The present invention provides a photochromatic performance optimization method and optimization system of a multi-color light source. The optimization method includes the following steps: according to the spectral sensitivity curves of photopic vision, scotopic vision and non-visual The light-color light source calculates the spectral radiation efficiency, scotopic spectral radiation efficiency and non-visual spectral radiation efficiency, and determines the corresponding contour map; performs binary function fitting on the contour map to calculate the spectral radiation efficiency, scotopic spectrum Radiation efficiency and the corresponding contour value of non-visual spectral radiation efficiency; according to the contour value of the contour map and the corresponding spectral radiation efficiency, the gradient change of the contour map of each chromaticity point in the color gamut class is obtained; according to the contour value of each chromaticity point in the color gamut class The gradient change of the iso-height map obtains the gradient value of each chromaticity point of the color gamut class. The optimization method can uniformly optimize multi-color light sources, and can predict the light and chromaticity performance change rules of multi-color light sources, which can save energy to a great extent.

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...
