Healthy illumination system capable of effectively regulating and controlling circadian rhythm of human body

Abstract

The invention provides a healthy illumination system capable of effectively regulating and controlling circadian rhythm of a human body. The natural light is guided into a spectrum sensor module through a sealed reflector module to be analyzed to form a natural light spectrum, and the natural light spectrum is stored and sent to a central processing subsystem; a feedback processing module receivesthe illumination light fed back by an LED illumination subsystem and draws an illumination spectrum image to be transmitted to the central processing subsystem; a main control microcomputer module isused for classifying the natural light spectrums transmitted by a spectrum acquisition subsystem, analyzing the change tendency of circadian rhythm illumination CIL value and CAF value which are universal to natural light spectrum in one day, drawing out various target spectrum information in different time within one day by combining with the circadian rhythm curve of the human body, and simulating a target spectrum through a progressive method; and by comparing the simulated target spectrum with a lighting spectrum, the lighting spectrum is optimized to obtain a lighting spectrum closest tothe target spectrum.

Description

technical field [0001] The invention belongs to the field of healthy lighting sources and relates to the regulation of lighting on human body's circadian rhythm. Background technique [0002] Today, LED-based semiconductor lighting has rapidly replaced traditional lighting technologies due to a series of advantages such as high energy efficiency, long life, small size, fast response, environmental friendliness, and flexible spectrum. However, the white light of LED lighting is usually rich in blue light, and the ipRGC in the human eye is most sensitive to blue and blue-green short-wavelength light. Therefore, compared with natural light sources, people's circadian rhythm and sleep quality are susceptible to adverse effects when exposed to LED lighting at night. Long-term exposure to LED lights will aggravate the negative emotions of the human body. [0003] Many problems caused by LED light sources are emerging day by day, especially in hospitals, this effect will be more ...
