Current domestic LED enterprises should strive to explore the special areas of LED

For the domestic LED industry, LED upstream technology is monopolized by the international giants, the middle reaches of the same is true, and now the most important thing is to design a better downstream products, the price can be more reasonable. "Recently, the China web hosting, NVC lighting operations center in Shenzhen hosted the" low carbon energy saving lighting, global LED lighting product design, application and Innovation Forum "held in Guangdong, Dongguan, Fudan University Institute of electric light source of Liang Rongqing as the theme of the report on the current development of domestic LED industry. Wang Jinsui, honorary director of the China Illuminating Engineering Society, and director of the Institute of urban lighting planning, Beijing University of Technology, and hundreds of people in the field of lighting engineering, attended the forum of the.

The upper and middle reaches of the foreign enterprises

Liang Rongqing introduction, LED industry is divided into upstream, midstream, downstream three parts. Among them, LED chip technology belongs to the upstream industry. In the 350 power density, the current international LED chip technology to a very mature stage, especially the development of sapphire substrate in foreign countries faster and faster. At present, the mainstream international LED companies, such as OSRAM, PHILPS, in this regard has made a breakthrough, and this is the weakness of domestic LED companies.

LED midstream industry is the assembly link. Liang Rongqing introduction, and now the general tooling with SMD, high-power lighting is a ceramic substrate. In this regard, the domestic enterprises have certain advantages, but also basically for foreign enterprise monopoly.

For the domestic LED industry, LED upstream technology is monopolized by international giants, the middle reaches of the same is almost the case, and now the most important thing is to be able to design a better downstream products, and prices can be more reasonable. Liang Rongqing said.

LED special areas used to be excavated

In order to gain a competitive advantage in the LED industry, in addition to the pursuit of "I have excellent", the creation of "I do not have" brand and technical superiority is the winning weapon. This requires enterprises to understand and master the latest technology, to get involved in new areas.

Liang Rongqing introduction, in the field of solid state lighting, in addition to simply replace the traditional light source, LED light source for lighting design provides more applications, some of the hot research and development. In particular, he introduced the use of LED in some special areas. Such as LED visible light communication, Fudan University in the domestic front; - plant, fill in the beauty of applications and LED in non visual aspects of lighting. Jiangsu, a rice production base, often asked whether we can use LED light trap. We use LED to design the best light trap, combined with solar panels. Liang Rongqing cited an application case.

Liang Rongqing also depicts a number of gaps in the field of LED industry. "The study of visual science is also very important. What is the difference between different lights in different places? Such as the pilot, the cockpit inside the machine for a long time in the LED light source with the traditional light feel what is not the same? Liang Rongqing said.
