Description

System and method for regulating and controlling healthy light environment
Technical Field
The invention relates to the field of optics, in particular to a system and a method for regulating and controlling a healthy light environment.
Background
Since the non-visual effect of human eyes was discovered by human beings in 2002, the study on the change rule of human body circadian rhythm caused by stimulating a third light receiving cell of human retina by illumination becomes a hot problem concerned by the medical field, the influence of illumination on the circadian rhythm of a user is proved to be related to the constitution of an individual at present, the susceptibility of the individual with different constitution types to various diseases is different for the individuals with different constitution types, and the existing healthy light environment regulation and control methods are mainly as follows:
1. manually dimming according to the personal preference of the user;
2. setting a plurality of corresponding artificial light environments according to the mood of a user, and automatically selecting and adjusting the system by the user through self selection or behavior feedback;
3. setting a plurality of corresponding artificial light environments according to different visual work contents, and automatically selecting and adjusting a corresponding mode by a user or by behavior feedback;
4. according to the color temperature/spectrum, the light intensity and the distribution characteristics of natural light in different time periods in the daytime, a plurality of corresponding artificial light environments are set and are simulated in different time periods along with the change of outdoor daylight.
However, the above methods all perform dimming based on the subjective psychological feeling of the user or according to the change of natural light outdoors, and have the following obvious disadvantages:
1. hysteresis without taking into account the effect of illumination on physiology
Both methods 1, 2 presume a healthy light environment based on the user's psychological perception. However, the psychological feeling is not completely consistent with the actual physiological feedback index, and due to the existence of the time accumulation effect and the hysteresis of the physiological response, the light environment estimated according to the psychological feeling is not the most suitable for the healthy light environment of the user, and the judgment according to the psychological preference of the user is inaccurate.
2. The standard according to which the revision is required
The different modes in the method 3 are set based on national standards, but the theoretical basis formulated by the current national standards is still the same as that of the methods 1 and 2, namely the mode is determined by a visual psychology-based luminous environment preference selection experiment, the hysteresis of the physiological influence caused by illumination is not considered, and the method is not accurate enough.
3. The limited modes cannot meet the individual requirements for the diversification of the light environment
The method 4 is different from the first 3 modes, and is a more advanced dimming mode at present. However, different individuals have different constitutions due to various differences in race, gene, region, growth process and the like, and the adaptability to illumination is greatly different; the required illumination is different for each individual in different physiological stages, in different physical environments, for different visual tasks, e.g. when suffering from a certain disease, than the appropriate illumination for that individual in a healthy state; the change in physical environment will cause the optimum lighting for the individual to change. Therefore, the existing regulation mode of the light environment is difficult to meet the requirement of the individual on the diversity of the light environment.
