Output value is the current led road lighting in the domestic lighting market penetration of only 5%, core technologies rely on imports, and higher overall cost to become a stumbling block to hinder the further development of LED industry. “LED Engineering Research Institute, Dr. Xiao-Fei Zhang said.
LED chip is like a car engine. The lack of core technology will directly restricts the development of this industry. “Zhuang Shenan said. It is understood that the led road lighting upstream chip production technology lies in the hands of foreign companies, the slower the process of domestic technology, affecting the development of the industry. MOCVD epitaxial furnace and its related technology is the most high-end of the LED industry chain mainly dependent on imports, greatly restricted the cost control of the LED industry upstream.
“The overall level, the gap between China and the international first-class level, there is still about two years.” Feng-Yi Jiang believes that “in many developed and developing countries or regions in the world in accelerating the development of the semiconductor lighting technology and industry, technology , China in the second echelon.
Blind investment and lack of core technology makes led high bay lighting market in China was mixed, good and bad. Unstable quality is also a LED enterprises generally faced with a problem. “Some customers a higher price to go back to the LED lights, and even thousands of hours not last, and even the quality is not as good as traditional lighting led road lighting market, there are many small and medium enterprises for the production of low-quality products, the industry pattern of instability.” Zhuang Shenan said.
