Description
Technical Field
The invention relates to the technical field of lighting, in particular to an indoor lighting system and method applied to light color control.
Background
On the application level, the quality of the indoor light environment is affected by architectural design, indoor design and lighting design. The building design determines the size of the window and thus controls the amount of solar radiation. The color and reflectivity of various surface materials such as ceilings, wall surfaces, floors and the like are determined by indoor design. The lighting design is responsible for the integration of artificial lighting and natural lighting and the indoor lighting quality. Current non-visual effect based lighting applications mainly comprise two directions. The first is to use the light as a therapeutic means to research the clinical application of phototherapy on diseases such as senile dementia, insomnia and the like. Secondly, for healthy people, the indoor environment quality is further improved by discussing how the illumination is used for maintaining the normal physiological rhythm of the human body, improving the working efficiency and relieving the emotional stress. As mentioned above, light can affect the circadian system of the human body, and it is this theory that light therapy is applied to regulate the body's biological clock and endocrine by appropriate light stimulation.
The human circadian rhythm is mainly controlled by the supraoptic nerve cross nucleus (SCN) of the hypothalamus, and the retina regulates the SCN-controlled human rhythm timing system by receiving the stimulation of the light intensity. Lack of light stimulation, or aperiodicity, can cause biological rhythm disturbances that create health problems. The alternation of day and night in the nature makes human adapt to the living frequency of 24 hours, and the human adapts to the natural light change in the area, and the dynamic change of the natural light meets the requirement of human rhythm. However, the current indoor lighting standard only meets the basic visual effect, the illumination intensity is constant, and the requirement of human rhythm cannot be met. The indoor lighting is used as a main place for people to work, live, study and move, and the lighting needs to be considered from the health perspective to meet the requirements of human rhythms.
The alleviation of seasonal physiological disorders (SAD) by phototherapy is currently widely accepted; early morning light stimulation received was shown to be effective in treating sleep disturbances in alzheimer's patients; moderate lighting can also help night shift workers adjust the biological clock to adapt to the work pattern of night work day. However, research results for phototherapy tend to be excessive, and scholars call for high-quality illumination for healthy people, and illumination received indoors is reduced by 40-200 times compared with that received outdoors. In addition to the table illumination intensity, many studies have focused on the near-to-eye illumination intensity, indicating that the index better reflects the dose of light acting on the non-visual effect, and individual studies suggest that the near-to-eye illumination intensity should reach 1000lx to meet the stimulation requirement of the non-visual effect. Most of the current indoor lighting can not meet the standard, so that manual illumination is needed for compensation. High color temperature (5000-6000K) illumination rich in blue light has higher non-visual light effect, and stimulation effect can be generated when the light is lower than 1000 lx. Generally, people do not have the same illumination requirements during work and rest, and therefore, dynamic illumination with variable light intensity and light color becomes a main object of the research.

In the present application, researchers have also studied the dynamic change curve of illumination intensity and color temperature that can satisfy the non-visual effect of people according to the one-day work-rest mode, as shown in fig. 2 and 3, fig. 2 shows the change curve of color temperature over time that can satisfy the non-visual effect of people, and fig. 3 shows the change curve of illumination intensity over time that can satisfy the non-visual effect of people. Wherein, researchers have also formulated the illumination intensity that can satisfy people's non-visual effect, the changeable dynamic lighting scheme of colour temperature according to the work-rest mode of a day: beginning at 8:00 in the early morning, the user just enters a work post, the cold white strong light stimulation mode can enable the user to adapt to the work environment more quickly, therefore, the illumination mode is determined to be the cold white strong light stimulation mode in the early morning, and the illumination scheme in the early morning is gradually changed into warm white low illumination intensity illumination from the cold white strong light stimulation mode. In the noon, the illumination is reduced to about 500lx at the lowest to ensure normal visual activity, and meanwhile, the environment created by low illumination intensity and warm color light is suitable for rest illumination, so that people can relax. After lunch, the illumination is increased to cool and white strong light stimulation again between 12:30 and 14:00 to excite the activity of the body, and then the illumination intensity is gradually reduced and the light color is changed to warm color. And (3) giving cold white light stimulation rich in blue light again between 17:30 and 18:00 towards the end of one day of work, wherein the stimulation amount is slight, the illumination intensity is not improved, and the fatigue feeling of one day of work is relieved only through the change of the light color. Similar dynamic illumination sets up work and rest illumination respectively according to the rule of work and rest of working day, promotes work efficiency, thereby improves the mood and does benefit to human health. With the development of the LED industry, white LEDs are receiving much attention for indoor lighting. Compared to conventional fluorescent lamps, LEDs have a more continuous spectral characteristic, which not only affects the visual perception, but may also bring about different biological effects.
