LED industry faces three major bottlenecks

Recently held in the "2011 Chinese low carbon economy industry development forum, LED lighting company Leidi photoelectric technology (Shenzhen) company chairman Deng Weiye said, the current 90% LED business losses, because many domestic manufacturers lack core technology, in R & D investment is very small.

In the country to promote energy-saving emission reduction and low carbon economy in the background, the rapid development of LED lighting industry. Ministry data show that from 2011 to 1 in April, LED investment in the industry to maintain rapid growth, the amount of investment has more than 30 billion yuan, the growth rate of more than 90%, becoming a veritable investment hotspot. At present the four semiconductor lighting industry in the Pearl River Delta, Yangtze River Delta, northern area, Jiangxi area and Fujian area gathered in China has initially formed the epitaxial wafer chip preparation, production, packaging, integrated application of LED industrial chain formed.

Policy support, "the first priority theme of semiconductor lighting products in the national long-term science and technology development plan" will be of high efficiency and energy saving, long life "included in the key areas and priority themes", local governments have also increased the industryssupport.

However, with the promotion of favorable policies, the domestic LED industry blowout development has also exposed many problems. Insiders said that the lack of core technology, poor liquidity and lack of industry standards and other issues seriously hampered the development of the LED industry.

According to the deputy director of ICT Dun & Bradstreet division Zhang Benhou introduced LED epitaxial wafer and chip industry accounts for about 70% of the profits, accounting for about 10%-20% LED application package, accounting for about 10%-20%. At present, the country's more than 4 thousand LED companies, mostly in the packaging and downstream sectors, in the industry's most critical substrate material technology, epitaxial wafer production core equipment, technology patents have long been monopolized by foreign companies. MOCVD (special equipment, the growth of GaN thin film GaN is the main material used to make the LED light emitting diode) epitaxial furnace and related technology is the most high-end LED industry chain, mainly rely on imports to restrict the upstream industry chain cost control.

In addition to technical constraints, LED lighting is also facing the lack of testing standards embarrassment. Chinese people's Bank Financial Research Institute senior researcher Liang Meng said, at present, some energy company has become the "light bulb", before the building in the light bulb again, how to achieve energy-saving effect to the lack of standards. More importantly, in recent years, LED lighting in a large area of landscape lighting and road lighting, the lack of standards will result in the construction of low repetition, waste of resources is not conducive to the long-term development of the industry.

Compared with the core technology, the lack of standard testing standards, the lack of cash flow on the impact of LED lighting companies more directly. According to reports, the construction, development, marketing and other expenses have occupied the enterprise funds, and some LED companies even offer free products, only rely on the way of contract management, the recovery of funds, which makes some enterprises on the brink of collapse.
