An intelligent lighting control method for simulating sunlight spectrum mode

Abstract

An intelligent lighting control method simulating a daylight spectrum mode, used for a long-term workplace for personnel with side lighting, comprising the following steps: a lighting system with dimmable and color-tuning: a white LED lighting product with a dimmable color-tuning; Coordinated zoning method: The area is divided according to the distance from the side window; the control method is coordinated with the sunlight: the working time of the workplace may continue into the night, in order to avoid the adverse effect of high color temperature on human circadian rhythm, the The color temperature of artificial lighting should not exceed 4000K; natural light is preferred in the area A near the window, due to the high color temperature of natural light; the intermediate area B needs to take into account both natural lighting and artificial lighting, and the illuminance setting value of natural lighting + artificial lighting is 500lx; Mainly artificial lighting. The control of different lighting partitions to match the sunlight mode enables it to achieve the purpose of energy saving under the premise of ensuring the user's needs and the premise of comfort and health.

Description

technical field [0001] The invention relates to a lighting control method, in particular to an intelligent lighting control method for simulating a sunlight spectrum mode. Background technique [0002] The light environment of people staying for a long time or the workplace is usually the result of the combined effect of natural light and artificial lighting. During the daylight hours, daylighting is mainly used, which has a positive effect on energy saving and light environment. During the period of insufficient lighting, artificial lighting is supplemented. , which is the basic strategy for combining daylight and artificial lighting. However, sunlight is unstable, and it changes greatly with time and space, and the sunlight resources in different regions also vary greatly. This difference and change is not only reflected in the illuminance or brightness, but also in the spectrum. Conditions, different seasons, and different times of the sky spectrum have great differences...

AI Technical Summary

Problems solved by technology

However, the existing rhythmic lighting focuses on imitating the illuminance and spectrum changes of sunlight through artificial lighting. The differences in the indoor lighting conditions of the building are adjusted accordingly, and the artificial lighting and lighting are not organically combined

At the same time, the existing technology does not take into account the different needs of non-visual effects and visual operations, and fails to give full play to the characteristics and advantages of daylighting and artificial lighting.

[0005] Aiming at the problems that the current rhythmic lighting does not consider the difference of sunlight spectrum in different areas of the sky and the linkage control with daylighting, this invention proposes an intelligent lighting control method that simulates the actual sunlight spectrum mode. According to the characteristics of light and climate in our country, and coordinated with the indoor lighting conditions, it can meet the physiological and psychological needs of personnel for a dynamic light environment, and provides a healthy lighting solution based on non-visual and visual ergonomics, which is suitable for long-term stays in offices and other personnel and place for visual work
