LED lighting is an important lighting module in integrated ceiling. The progress of LED lighting technology will directly drive the development of integrated ceiling industry and form advantages in lighting effect. At the same time, the cost reduction brought by technological progress can also form a price advantage. Semiconductor lighting technology is not limited to chip manufacturing and packaging technology, but a system-level technology including optical design, heat and power management. In terms of current LED performance, the use of cluster LED driven by low voltage and constant current causes that semiconductor lighting lamps must solve the problem of dissipation of huge heat and power management caused by conversion from AC mains to low voltage constant current. In addition, the small light flow and high brightness of the traditional packaged power LED will cause very serious glare. From the LED epitaxial wafer to the final lighting lamps need to go through a series of industrial chain links such as the design and assembly of die packaging lamps made by material epitaxial chips. On the one hand, from epitaxial wafers to final lighting and display applications, each link of the industrial chain can form independent products, and has its own technical barriers and research and development needs; On the other hand, the quality of terminal application products will be affected by each link. For example, the core component of semiconductor lighting is LED chip, but the luminous efficiency of LED chip reaches 100lm/W, which does not mean that the efficiency of semiconductor lighting lamps also reaches 100lm/W; More importantly, in order to gain market recognition, semiconductor lighting products must have obvious advantages over traditional lighting products in terms of comprehensive performance including lamp efficiency, reliability and human eye comfort. In other words, even if the efficiency of semiconductor lighting reaches 100lm/W, it does not mean that it will be accepted by the market. Semiconductor lighting itself still has many scientific problems to study, for example, lighting effect and quality include color rendering, color consistency, human eye comfort, etc. Only when the development and maturity of technology makes semiconductor lighting lamps have advantages over traditional light sources in terms of efficiency, lighting quality and design novelty, can semiconductor lighting enter and continuously open up the market. On the other hand, the expansion of the market will promote the expansion of production and the increase of research and development investment in the industry, accelerating technological progress, thus improving performance and gradually reducing cost and price.
