LED industry needs innovation and research hot"

In recent years, China's LED heat is just the concept of heat, rather than innovation, research and development hot. "In July 29th, China Academy of Engineering in chemical engineering, metallurgical and materials engineering department, national new material industry development strategy advisory committee, Taiyuan University of Technology, Shanxi Feihong Photoelectric Technology Group Co hosted the" China Academy of Engineering LED industry and application of high-level international seminar ", Chinese academician Zhou Lian explains my face the problem in LED industry.

This seminar, 11 Chinese academy, academician China Academy of engineering and from the LED field at home and abroad more than 100 experts and scholars, to strengthen the LED lighting industry technology innovation chain construction, explore the LED product development and new business models, to avoid the low-end industrial chain overheating issues discussed.

Stepping up industrial layout

Semiconductor lighting technology, as the fourth generation of lighting technology, its low energy consumption, long life, high luminous efficiency, so it has been widespread concern around the world.

Director of the Institute of semiconductor lighting research and development, semiconductor lighting joint innovation national key laboratory director Li Jinmin said: LED lighting industry as a strategic emerging industries, can promote the upgrading of traditional industries. In recent years, the United States and the United States and other countries and regions have implemented the semiconductor lighting development plan, stepping up the layout of the LED lighting industry. Because LED lighting has many advantages, in June 2003, the Ministry of science and technology led the establishment of a national semiconductor lighting project coordination leading group, opened the prelude to the domestic LED lighting industry. National semiconductor lighting engineering research and Industry Alliance Secretary General Wu Ling said.

In February this year, in order to guide the healthy and orderly development of semiconductor lighting industry, to promote energy conservation, the national development and Reform Commission and other 6 ministries for the "planning" semiconductor lighting industry, proposed in 2015, 60W more than ordinary incandescent lighting will be fully eliminated, the market share will drop to below 10%, and the LED function lighting market share is expected to reach more than 20%, LED LCD backlight, landscape lighting market share will reach 70% and more than 80%.

The experts also said that the current LED lighting market in China has formed a certain scale of the industry, but also faced technical support for sustainable development of industrial agglomeration, resources are not enough, the development environment need to be optimized, business promotion mode needs further exploration and other problems.

Integration technology breakthrough

LED lighting industry chain is long, many key technical points, most companies can lead in a certain point, the leading domestic R & D institutions and a lot of technical points, but the core technology of LED lighting system integration applications. Said Zhao Liancheng, academician of Chinese Academy of engineering.

In recent years, a number of well-known institutions of higher learning, scientific research institutes, have carried out the research and development of LED. At present, China's LED lighting core technology in the field of patent applications more than 50, to solve the previous LED lighting service life is short, serious glare, poor energy efficiency, bulky appearance, high prices and other issues.

Among them, with the core patent technology breakthrough and integration of Taiyuan University of Technology, China's main high-end accessories for lighting system integration products no longer rely on imports, also breaking the monopoly of foreign advanced technology in the field of semiconductor lighting, grasp the initiative in the semiconductor lighting industry.

High brightness blue and green LED epitaxial wafer of the school research and development (ZHCH-W) and chip (ZHCH-C) on 2004 by the state 4 ministries identified as national key new products, key products LED, LD wafer and chip, reached the international advanced level.

At present, Taiyuan University of Technology has begun to export patents, technology, management, brand and standards. At the same time, the school development and personnel training platform of Shanxi Feihong micro nano Photoelectric Technology Co. Ltd. Shanxi Linfen Ganting new energy materials Industrial Park is also relying on the good momentum of development.

Innovation challenges

However, in the past few years, due to the lack of core technology and patents, the LED industry is a serious problem of low-level blind investment. 70% of our enterprises can only be confined to the lower reaches of the low threshold of low technical content of the packaging and assembly links, low level competition. Zhou Lian said.

Zhou Lian believes that in the promotion of the state and policy support, the manufacturing cost of China's LED lighting products continue to decline, LED lighting market demand continues to expand, has formed a certain scale of the industry, but there are also many challenges.

First, the sustainable development of technical support is not enough, lack of research and development support, power decentralization.

Two industrial resources are not gathering, the urgent need to integrate the industrial structure. Small scale and scattered enterprises, the concentration is not high, the regional distribution of the industry showed a trend of decentralization, high-end products and leading talent shortage.

Three is the development of the environment needs to be optimized, the policy did not form a cohesive force, standards, testing and certification system to be improved.

Four is the lack of core technology patents, research cooperation loose. Although the luminous efficiency of LED is increasing, there are still some problems that need to be solved, such as low conversion efficiency, poor heat dissipation performance, the color index of warm white LED lighting and the difficulty of color temperature control.

The experts pointed out that the depth of the industry chain integration has become the trend of LED development, enterprises should increase investment in research and development, core technology and system integration innovation to cope with the challenges, in order to obtain a greater voice in international competition.
