Spectrum optimization method and system for four-color LED light source to alleviate jet lag

Abstract

The present disclosure discloses a spectrum optimization method and system for four-color LED light sources to alleviate jet-lag response. Firstly, the lower limit and upper limit of the correlated color temperature are set and converted to the corresponding CIE 1931 chromaticity coordinates; then based on the physiological Rhythm model and CIE color rendering index, under this chromaticity coordinates, use the spectral power distribution and tristimulus value of each light color LED to construct a spectral optimization model; finally use the constrained optimization algorithm to solve it, and then determine the four-color LED light source mitigation Optimal spectral power distribution for jet-lag. To solve the problem that the current passenger cabin adopts four-color LED light source lighting and lacks a spectrum optimization method for alleviating passenger flight jet lag. This method optimizes two sets of optimal spectra while ensuring the light quality required for general lighting, which can provide Alleviate passengers' flight jet lag and provide the best light environment; make full use of the spectrum adjustable advantages of four-color LED light sources, and provide technical support for the design and development of cabin lighting sources.

Description

technical field [0001] The present disclosure relates to the technical field of LED lighting, in particular to a spectrum optimization method and system for alleviating jet-of-flight response of a four-color LED light source. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] During long-distance transoceanic travel by air, after flying across multiple time zones, most people experience different degrees of jet lag, such as sleep disturbance, headache, gastrointestinal discomfort, cognitive and motor function decline and other uncomfortable symptoms, which are often It takes a few days or even a dozen days to be relieved, which is commonly referred to as jet lag. The generation of jet lag is mainly due to the fact that the human body's circadian rhythm system time (biological clock) is not synchronized with the external time, forcing it to ...
