A control system and method for a healthy light environment

Abstract

The invention provides a regulating system and a regulating method for light environment. The system comprises a data collecting unit, a control unit and a data processing unit, wherein the data collecting unit is used for collecting parameters of an individual and environmental parameters around the individual; the control unit is used for adjusting the light environment around the individual; the data processing unit is connected with the data collecting unit and the control unit, is used for generating and sending configuration parameters to the control unit according to the collected parameters of the individual and the environmental parameters, and the control unit adjusts the light environment according to the configuration parameters. According to the system and the method providedby the invention, the physical environment in which a light environment user is located and various representative physiological and psychological indexes of the individual are monitored in real time,then various light environment parameters of the environment are regulated in real time, so that the compatibility among the illumination, physique, visual tasks and the like is enhanced, and the real-time healthy light environment which is most suitable for individual physiological and psychological conditions of the user is obtained.

Description

technical field [0001] The invention relates to the field of optics, in particular to a control system and method for a healthy light environment. Background technique [0002] Since humans discovered the non-visual effects of the human eye in 2002, the study of the human body's circadian rhythm changes caused by light stimulation of the third light-receiving cells of the human retina has become a hot issue in the medical field. The impact of the user's circadian rhythm is related to the individual's physical fitness. Individuals with different physical types have different susceptibility to various diseases. Currently, there are roughly the following methods for healthy light environment regulation: [0003] 1. Manual dimming according to the user's personal preference; [0004] 2. According to the user's mood, set several corresponding artificial light environments, which are selected by the user or through behavioral feedback, and the system automatically selects and adj...

AI Technical Summary

Problems solved by technology

[0011] The different modes in method 3 are set based on national standards, but the theoretical basis of the current national standard formulation is still the same as that of methods 1 and 2——determined based on the light environment preference selection experiment based on visual psychology, without considering the impact of light on the environment. Hysteresis of physiological effects, not accurate enough

[0012] 3. The limited mode cannot meet the diverse needs of individuals for the light environment

Therefore, the existing adjustment methods for the light environment are difficult to meet the diversity requirements of individuals for the light environment.
