LED lighting will be innovative and industrial technology development

2011 China (Shanghai) international semiconductor lighting technology forum held in Shanghai Zunyu Himalaya Hotel on July 6, 2011, the Shanghai municipal government and the Shanghai Municipal Science and Technology Commission leadership speech and wish the conference a success, while ledinside series stories state group chairman Liu Jiong Mr. long humorous "discovery, invention and creation of the 3 A great number of opinions" and for the macro semiconductor lighting industry creative. Opening ceremony in the climax of the end of the first day of the forum keynote speech, LED lighting and related industries, a number of scholars and experts from different angles to give their thoughts and insights on industrial development.

Dr. Zhu Junhao of Shanghai semiconductor lighting Engineering Research Center for China semiconductor lighting industry development situation, from the core competitiveness of the semiconductor lighting performance, development direction and how to cultivate the core competitiveness of the three angles to provide some thoughts for the healthy development of Chinese semiconductor lighting industry. Zhu Junhao pointed out that when the LED effect of light after 100lm/W, the technology will be divided into two directions, that is, the development of innovative technology and the direction of the development of industrial technology. China's semiconductor lighting market is currently at a low level, and presents a resource based competitive landscape. China's semiconductor lighting industry should strengthen international cooperation, expand production capacity at the same time, in the core R & D efforts, and constantly enhance its core competitiveness.

PHILPS lighting (Philips Lighting) professional lighting business Deputy General Manager Jeap Schlejen made a entitled "global market trends" report of the LED lighting system, analyzes three key segments: outdoor lighting, commercial retail and office lighting LED lighting area according to the development status of the market. He pointed out that people in different fields is different demand for lighting, semiconductor lighting industry needs better light, and constantly open up new areas of application, but also the development of digital technology and the combination of the concept of beyond lighting into reality. 2015 LED lighting is expected to reach 80 billion euros market share.

Nakamura Shuji, the father of Blu ray LED, focuses on the practical needs and the latest development of the research on polar and semi polar LED technology from the perspective of the latest developments in technology. He pointed out that the team began the development of polar and semipolar LED from 2000, 2007 the related mechanism of this technology in Japan to provide energy efficiency under the action has been significantly improved, but there still exist the problems of size is too small and expensive need further research to solve.

Chen Kun, vice president of OSRAM Semiconductor Co., Ltd., said in a speech, science and technology has always come from the needs of human nature. Solid state lighting is growing at an average annual rate of 45%, and the economic benefits of product performance will grow rapidly over the next ten years. Cost, quality and applicability has become the focus of attention, low energy consumption and more simple use is also the goal of OSRAM. In the future, the combination of semiconductor lighting and electronic digital system will achieve the effect of bright, bright and bright. To achieve this goal, we need to make efforts from the aspects of design and function, sustainability, efficiency, standardization, reliability, low cost and so on.

GE lighting Asia Pacific LED Product Manager Wang Jian began to throw a specific practical problem, that is, a specific Japanese baseball field is suitable for LED lighting, causing everyone's curiosity and thinking. He pointed out that from the perspective of consumer expectations, the two issue is more critical, that is, the quality of LED lighting products and return on investment. LED can replace the traditional lighting products, not only in the comparison of light efficiency and brightness, but in a specific application of the comparison, with the least light to achieve the same lighting effect. The investment return rate of many factors, should be based on the special use of the environment, taking into account the electricity tariffs, system costs, can withstand the purchasing power of many factors.

Veeco's MOCVD marketing director, Dr. Li Jia, delivered a lecture entitled "reducing the manufacturing cost of LED through advances in film deposition technology". He pointed out that high brightness LED is currently in the early stages of development, and its main driving force is the TV Backlight Market and general lighting market. With the further increase of LED backlight market penetration and lighting market opened, the sustainable development of the industry to promote the dual light efficiency and cost reduction, as a key equipment of the industrial chain of MOCVD, accounted for about 50% of the business capital output, for the thin layer LED control, thereby affecting the LED color uniformity, luminance and electronic the characteristics play an important role. Continuous improvement of 5 factors, which are high cost sensitivity, such as yield, brightness, capital efficiency, machine recovery and application of gas. In the machine base material, size, process flexibility, manufacturing environment, system reliability and maintainability, and other aspects of the breakthrough. Following the high degree of market acceptance of K46i, Veeco and the new MaxBright series products.

The other MOCVD manufacturers Aixtron Christan Greater China, Dr. Geng also made a report, he pointed out that the large size of the wafer is an important direction of industrial development, the consistency and the yield is MOCVD devices for the rapid development of industry, Christan Geng shows the production process of Aixtron automation, and said very seriously Chinese market at present the agency has been established in Shanghai, and Shanghai as the center of radiation throughout the Chinese, in Wuxi and Shanghai have related technical support, Aixtron has also recently established in Suzhou.
