According to the statistical data of the State statistics bureau: in 2018, the general population of the continent of China is 139538 million people, from the aspect of urban and rural structures, the constant population of towns is 83137 million people, the constant population of villages is 56401 people, and the ever-increasing population of towns makes people put forward more demands on living environments.

Urban population increases, and urban resources are more and more tense, so that urban space is continuously developed towards two dimensions of sky and underground. In fact, people in cities are indoors most of the time, whether they are working or leisure. Therefore, the improvement of indoor environment is an urgent need. According to statistics, the residence time of people in the room is as long as about 80%. With the improvement of living standard, the requirement of people on the comfort of indoor living environment is higher and higher. People's interest in indoor environments is mainly reflected in several aspects of thermal environments, air quality, acoustic environments and light environments.

The lighting environment is a key factor for the composition of the indoor environment, and 87% of the information acquired by people by means of sense organs comes from vision. The improvement of indoor illumination quality is a necessary link for people to pursue high quality of life and work at present when economy develops rapidly. For the indoor environment, the heat and sound environment are comfortable, and the light quality also influences psychological and physiological factors such as mood change, fatigue degree and the like of indoor personnel, so that the working efficiency is determined to a great extent. With the continuous development of illumination conditions and illumination research, people expand the illumination of an indoor environment by a lighting system to improve the visual comfort of user experience.

The surge of tall buildings and changes in public facilities has been found to have spent a large portion of their lives in artificial lighting conditions. For people who work indoors for a long time and even live in underground environment, the white light sources such as LEDs are not friendly enough, people who work indoors for a long time in such environment are prone to fatigue, and the happiness of people who work indoors for a long time are reduced. Compared with light sources such as indoor LEDs, people are more familiar with and love natural light caused by sunlight penetrating through the atmosphere, the light source enables the life of the earth to grow vigorously, the sunlight and the sky interact at different moments such as morning, noon and evening, and the scenes of gorgeous and colorful sunglow and sunset are provided, so that people tend to be happy and relaxed.

The existing indoor illuminating lamp only has the function of preliminary illumination, direct illumination and dazzling, and cannot simulate natural light, so that people are easy to fatigue and anxious in the environment for a long time, and the working efficiency is reduced.
