LED industry will focus on the lighting industry. Means that the lighting will be important areas for future development of the LED industry prospects and the current situation of the industry is how? Needs to be done to change i t?
LED performance in terms of the current caused by the use of low-voltage, constant current drive of the cluster of fluorescent tubes semiconductor lighting must solve the problem of significant amounts of heat dissipation and the AC mains to the low-voltage constant-current conversion and power management. In addition, the small lumen of the traditional power LED package, high-brightness light-emitting characteristics can cause very serious glare. Therefore, the semiconductor lighting technology is not limited to the production and packaging technology of the chip, but an optical design, heat and power management, including system-level technology.
LED epitaxial wafers to the final lighting produced through the material epitaxy → chip → die package → lighting design and assembly of a series of industrial chain. The one hand, from epitaxial wafers to final lighting and display all aspects of the application, the industrial chain can form a stand-alone product, and has its own technical barriers and R & D needs; the other hand, the quality of end-use applications products will be subject to every aspect of the impact.

LED lighting development of integrated technology and market with both hands
For example, the core component of semiconductor lighting the LED chip, but the sad light bulbs chip light-emitting efficiency of 100lm / W, does not mean that the semiconductor lighting efficiency reach 100lm / W; more importantly, semiconductor lighting products to gain market recognition luminaire efficiency, reliability, human eye, comfort, etc., including performance relative to traditional lighting products have a distinct advantage. In other words, even if the semiconductor lighting efficiency of 100lm / W, does not mean it will certainly be able to market accepted by the semic onductor lighting there are many scientific issues need to be studied, such as lighting effects and quality, including color, color product consistency, and comfort of the human eye.
The expansion of markets will lead to the increase in production expansion and industry R & D investment, accelerate technological progress, so that the performance gains and costs and prices gradually decline. On the other hand, only semiconductor lighting technology enables relatively conventional light sources advantage in efficiency, lighting quality, innovative design, etc., semiconductor lighting is possible to enter and continue to explore the market.
