"Four mountains" hidden behind the LED industry"

LED lighting industry in 2013 is destined to be an extraordinary year, the giants fall over each other admission, LED lighting seems to have become the meat and potatoes. In each of the major lighting companies continue to cheer for their 2013 results reported, but few people are concerned about the difficulties faced by the LED lighting forward process.

As far as the current situation is concerned, the LED industry is facing some problems at the present stage, which is solved by the way of merger or expansion. Some senior LED lighting technology engineer said, LED lighting is currently facing repeated local investment, lack of core technology, lack of lighting standards and funding chain tight four major problems. These four problems, the country is one of the major lighting giant called LED lighting on the road ahead of the four mountains.

Where repeated investment industry is ripening"

Previously, regardless of national policy to promote the market itself, or fried heat, laid the LED lighting the "God's favored one" status. Including China's ban on incandescent lamps in October last year, and almost all the way to pave the way for LED to replace its market share. For a while, do not talk about LED lighting chamber, it is not just the night returned to liberation seems so simple, not to be back to the Middle Ages "which the dark corner. However, whether in industry or outside the industry, not too many people really understand LED, most of the others, Qushifushi, also let the LED lighting market prosperity with a representation of the layers of fog and foam piles.

NVC CEO Wu Changjiang said, LED industry blind expansion of production capacity, the market demand is not synchronized with the terminal. According to research report data analysis, in 2012 China's semiconductor lighting industry, although the overall growth of 23% over the previous year, but the growth rate slowed and the lowest growth rate.

The maturity of the LED market is hot, but there is a contradiction between the broad prospects of LED applications and the current is not optimistic. LED as a new generation of green light, government efforts to promote the application of "strong twist but no ground for blame, not out of Muskmelon" truth in cold warned us, the subjective intention and objective promotion actually popularization, it is often. The so-called "days to rain, to marry a woman", it should at least be "free love", rather than "arranged marriage". To achieve the true meaning of universal, when this is to allow the market to gradually accept the LED, while the non artificially to the LED with a limited subscription mode hard sell to the market and the public.

Lack of core patents dominate the industry out of control

Over the past 10 years, the rapid growth of semiconductor lighting market, LED intellectual property rights has become the focus of the international semiconductor lighting industry competition. The global intellectual property of LED pattern, the core patent industry by Nichia chemical company, Japan's TOYOTA company, CREE company, the synthesis of PHILPS and Germany's OSRAM company lumens 5 leading manufacturers. In recent years, although the number of mainland China LED patent application volume increased significantly, has surpassed the United States ranked second in the world, but China's position in the global LED intellectual property in the pattern has not been fundamentally improved. On the contrary, LED intellectual property is becoming a bottleneck restricting the development of China's LED semiconductor lighting industry, the homogenization of competition caused by the intellectual property problem is getting worse, lack of initiative in the industry is becoming increasingly serious, risk of trade friction is also increasing. Breaking through the LED Patent Containment of foreign enterprises, and resolving the industrial crisis caused by the LED intellectual property rights, has become the key issue of the development of LED semiconductor lighting industry in china.

The LED patent in China is mainly concentrated in the middle and lower reaches of the middle reaches of the downstream packaging applications, patent applications accounted for 64% of the total. In relation to the long-term development of the industry, the key technology is still lack of core patents.

From the evolution process of global patent LED, LED China's patent application process behind Japan, the United States, missed the early development stage of patent technology in the first stage and second stage patent technology cultivation incubation stage, directly into the application stage of industrialization of patent technology. The impact of the development of China's LED patent is not balanced. From the patent type, LED patent in our country with the utility model and design patents, invention patents accounted for relatively low, the domestic LED utility model patents accounted for 59%, design patents accounted for 15%, while the LED invention patents accounted for only 26%.

China's LED patents are mainly concentrated in the middle and lower reaches of the field, midstream packaging, downstream applications accounted for 64% of the total patent applications. The largest number of applications LED applications, accounting for about 43% of the total patent, LED packaging accounted for more than about 21%, epitaxial and chip accounting for the proportion of 18% and 17%, respectively, the substrate accounted for more than about 1%. In the aspect of epitaxy, the gap between the domestic and the foreign countries and the buffer layer technology patent. On the chip, the domestic chip shape technology, surface roughness technology and substrate stripping and bonding technology patents. Packaging technology, the rapid development of China's patent technology, but the base material patents and fluorescent material patents and foreign gaps. Especially in relation to the key sectors of the industry's long-term development, China is still lack of core patents, such as Blu ray LED excited white lightphosphor technology, graphics technology, LED chip substrate vertical structure technology, flip chip packaging technology and pulse width modulation PMW power drive technology etc..
