LED lighting technology to accelerate the pace of development to achieve cost reduction

LED lighting is the main green light in twenty-first Century. LED lighting technology is not only limited to the chip production and packaging technology, but a system design, including optical design, heat and power management, etc.. The performance of LED in terms of the use of low pressure, constant current drive due to the dissipation of cluster LED semiconductor lighting must solve the great heat and from AC power to low-voltage constant current switching power supply management problems caused by. In addition, the traditional packaging power LED small luminous flux, high brightness light-emitting characteristics will cause very serious glare.

From the LED epitaxial wafer to the final lighting fixture, it needs a series of industrial chain links, such as material epitaxy, chip manufacturing, core packaging, lamp design and assembly. On the one hand, from the wafer to the final lighting and display applications, all aspects of the industry chain to form independent products, and has its own technical barriers and research needs; on the other hand, affecting the quality of terminal application products will be each link. For example, the core component of semiconductor lighting is LED chip, but the luminescence efficiency of LED chip to 100lm/W, is not equal to the efficiency of semiconductor lighting has reached 100lm/W; more importantly, semiconductor lighting products to gain market recognition, comprehensive performance including efficiency, reliability, light of human comfort, compared with the traditional lighting the product must have obvious advantages.

In other words, even if the semiconductor lighting efficiency reached 100lm/W, it doesn't mean that it must be accepted by the market, semiconductor lighting itself there are many scientific problems need to be studied, such as lighting effects and quality including color, color consistency, human comfort etc..

The expansion of the market will lead to the expansion of production and investment in R & D investment, accelerate technological progress, so as to enhance performance and cost and price gradually declined. Only when the development of technology makes the semiconductor lighting in the efficiency, lighting quality, design and other aspects of the advantages of the traditional light source, semiconductor lighting can enter and continue to open up the market.
