The patent of LED companies

[Text|High- tech LED reporter Wen Zhao] High-tech production research LED research institute (GLII) statistics show that in 2014 China's LED industry total output value reached 344.5 billion yuan, an increase of 31%. Among them, the output value of LED upstream epitaxial chips, midstream packaging and downstream applications were 12 billion yuan, 56.8 billion yuan and 275.7 billion yuan respectively, up 43%, 20% and 32% respectively.

Behind the beautiful data, there is also a "å°´å°¬". China's LED industry is large in scale, but it is still mainly concentrated in the middle and lower reaches of the industrial chain, which is the area with low added value. "The homogenization competition of enterprises in the downstream sector is more serious, mainly based on price wars." Zhang Hongbiao, research director of the High-tech LED Industry Research Institute, told reporters that the LED industry has lower thresholds in the downstream sector, competition is disorderly, and some have strength. The company simply turned its attention to overseas markets. According to GLII statistics, in 2014 China's LED lighting exports reached 8.79 billion US dollars, an increase of over 60%.

At present, China's LED lighting export market is mainly concentrated in Europe, America, Japan and other countries and regions, which in turn dominates the US market. However, due to patent issues, overseas companies can only focus on downstream sectors with thin profits or buy chips from abroad to avoid patent risks.

"In recent years, Chinese LED companies are gradually implementing the "going out" strategy, going abroad and going to the world market, but often when going abroad, LED patents have become an important part of the overseas development of Chinese LED companies." Talking about LED patent issues, Gong Wenru, chairman of Jingtai Optoelectronics, said.

LED patents for Chinese LED companies to go abroad have become the focus of recent industry attention. The industry insiders have described the LED industry patent issue as "the sword of Damocles", which is high above the top and may fall at any time.

In the United States, for example, the safety standard is the primary condition for LED products to enter the market. It mainly performs UL safety certification or ETL safety certification. Both are LED lamps UL1993 and LED module UL8750 based on American national standards. The standard is extremely strict with the requirements of the products, the certification costs are high and the cycle is long, which makes many domestic LED export enterprises discouraged.
