The necessity of the thesis The process of urbanization is fast people live and work mainly indoors under artificial lighting. The artificial lighting environment is different from natural light in terms of length spectral structure day and night cycle and the circadian rhythm of residents will be reversed and cause a lot of physical health consequences physiology and psychology such as insomnia obesity poor physiology infertility fatigue even cancer. Therefore creating a lighting environment for humans to protect eyevision and health is essential. In this thesis I will systematically present problems to be solved in the field of interior lighting derived from the knowledge about the role of light for people. Next is the design manufacture and application of solid lighting products on the basis of LED combined with free-form optical components in interior lighting. 2. The research objectives of the thesis Improve the usability and quality of LED-based lighting products. Develop a new generation of high-efficiency LED lights evenly distributed .
