Abstract

The invention discloses a method for modulating a daytime rhythm spectrum. The method comprises the following steps: providing a white light LED, a blue light LED, a green light LED and a blue-green light LED; adjusting the luminous flux of each LED to obtain a daytime rhythm spectrum with a preset luminous flux; wherein the luminous flux of the white light LED, the luminous flux of the blue light LED, the luminous flux of the green light LED and the luminous flux of the blue-green light LED account for 62.32%-75.9%, 1.74%-1.91%, 1.5%-20.27% and 15.5%-22.8% of the preset luminous flux respectively. By implementing the method, the daytime rhythm spectrum with high rhythm stimulation and high color rendering index can be obtained.

Description

technical field [0001] The invention relates to the field of luminescence spectrum, in particular to a modulation method of diurnal rhythm spectrum. Background technique [0002] The indoor light environment has a huge impact on human health. Empirical studies have shown that light can affect human vision, physiological functions, and behavior. According to the study, this effect of light is associated with light-sensitive retinal ganglion cells (ipRGCs). The light signal is transmitted from ipRGCs to the circadian rhythm center SCN, which can realize the regulation and control of the body's biological clock and various physiological activities. For the human body, when it is stimulated by light at a suitable time and intensity every day, it can well calibrate the rhythm cycle of the internal biological clock of the human body. If light stimulation of appropriate intensity and time is not obtained, this balance state will be destroyed, which in turn will bring great harm ...
