Only when the development of the technology matures makes semiconductor lighting fixtures gain advantages in terms of efficiency, lighting quality, novelty of design and other aspects compared to traditional light sources, semiconductor lighting can enter and continue to open up the market. LED lighting technology is not limited to chip fabrication and packaging technology, but is a system-level technology that includes optical design, heat, and power management. In terms of current LED performance, the use of low-voltage, constant-current-driven cluster LEDs has led semiconductor lighting fixtures to address the dissipation of large amounts of heat and power management issues caused by the conversion of AC mains to low-voltage constant currents. In addition, the small light-pass, high-brightness light-emitting properties of conventional packaged power LEDs can cause very severe glare.
The expansion of the market will promote the expansion of production and the increase of R&D investment in the industry, and accelerate technological progress, so that the performance will increase and the cost and price will gradually decline. From the LED epitaxial wafers to the final lighting fixtures, a series of industrial links such as material epitaxy, chip fabrication, die encapsulation, and lamp design and assembly are required. On the one hand, from the epitaxial wafers to the final lighting and display applications, all aspects of the industry chain can form independent products, and have their own technical barriers and research and development needs; on the other hand, the quality of terminal application products will be subject to each link. influences.
For example, the core component of semiconductor lighting is LED chips, but the LED chip's luminous efficiency of 100lm/W does not mean that the efficiency of semiconductor lighting fixtures has reached 100lm/W; more importantly, semiconductor lighting products To gain market recognition, comprehensive performance including lighting efficiency, reliability, human eye comfort, etc. must obtain significant advantages over traditional lighting products.
In other words, even if the efficiency of a semiconductor lighting fixture reaches 100 lm/W, it does not mean it will be accepted by the market. Semiconductor lighting itself still has many scientific issues to be studied, such as lighting effects and quality including color rendering and color. Consistency, eye comfort, etc.
The expansion of the market will promote the expansion of production and the increase of R&D investment in the industry, and accelerate technological progress, so that the performance will increase and the cost and price will gradually decline. Therefore, the rapid development of the international LED lighting market, is expected to reach 17.449 billion US dollars in 2010. China is not far behind in the field of LED lighting, China introduced a number of policies, and actively promote the development of LED lighting market, is expected to reach 21.661 billion yuan in 2010, an increase of 35.8% next year.
