"For China LED industry, LED upstream technology is monopolized by the international giants, midstream is almost so, now the most important thing is that whether the downstream can design better products with more reasonable prices or not", Rongqing Liang, director of Lighting Research Institute of Fudan University, expressed in view of the current development trend of Chinese LED industry.
Foreign Enterprises have Advantages in Upstream and Midstream
Rongqing Liang introduced that LED industry consists of upstream, midstream and downstream. LED chip technology belongs to the upstream industry. Under the Power density at 350, the current international LED chip technology comes to a very mature stage, especially the sapphire substrate, which has developed faster in overseas. Currently, the international mainstream LED companies like Osram and Philips have made a breakthrough in this regard, but which is the soft underbelly of Chinese LED enterprises.
The midstream industry is LED assembly areas. Rongqing Liang stated that now generally tooling with SMD; high power lighting adopts ceramic substrate. In this regard, domestic enterprises have certain advantages, but also basically monopolized by foreign enterprises.
"For the domestic LED industry is concerned, LED upstream technology is the international giant technological monopoly, midstream almost so, now the most important thing is downstream can design better products, and prices will be more reasonable." Liangrong Qing expressed.
To Discover the Application of LED in Special Fields
To gain a competitive advantage in the LED industry, in addition to the pursuit of "be more excellent than others", the creation of brand and technology advantage is a winning weapon, which requires companies to understand and master the latest technology and to be involved in new fields.
Rongqing Liang introduced that in the field of solid-state lighting, in addition to simple replacement of the traditional lighting, LED light source provides more applications for lighting design, some popular application development. He particularly introduced the application of LED in some special areas, such as LED visible light communication, the application of LED in non-visual lighting and cosmetic applications. Rongqing Liang also described the blank fields in LED industry. He added that the study on visual science is also very important.
