Research on regulated biological regularity LED light source based on normality test algorithm

In this paper, the optimal channel weight combination and the key parameters of the synthesized spectrum are obtained respectively for the two scenes of daytime illumination mode and night sleep aid mode. The question of whether optimal lighting has a beneficial effect on sleep quality compared to normal light and dark environment, we first used genetic algorithms (GA), a multichannel spectral synthesis model is established, and then five key performance indexes are solved and optimized. Then, the overnight sleep data of 11 subjects in three environments were processed. Six groups of data including total sleep time, sleep efficiency, sleep latency, deep sleep proportion, rem sleep proportion and wake times were extracted. Next, using the normality test model, we pass the KS test and SW test, concluded that optimal light does not improve sleep quality compared with normal light and dark environment.
