The seminar was held in the lecture hall on the second floor of the conference center of Xi'an High-tech Zone. The meeting held a heated discussion on the current technology and market development of the LED industry.
The conference attracted about 120 audiences from LED companies from all over Shaanxi. Chai Jie, deputy director of Xi'an Optoelectronic Technology Industry Development Center, Mu Yijing, general manager of Xi'an Liming Electronic Technology Co., Ltd., Duan Weifeng, director of Ke Rui Beijing Office, Gaogong LED CEO Zhang Xiaofei, Philips Lumileds Asia Regional Marketing Director Zhou Xuejun, Jiangsu Xinli Optoelectronics Co., Ltd. Sales Director Gu Zongjun delivered a speech.
Gaogong LED CEO Zhang Xiaofei: Indoor LED Lighting Technical Requirements and Market Analysis
In his speech, Zhang Xiaofei deeply analyzed the problems in the technology, cost and market of LED indoor lighting applications. He pointed out that many technical indicators of LED lights have not yet reached the level of popular application. In theory, the life of LED lights can reach 80,000-100,000. More than an hour, but currently only 20,000 hours can be reached technically. In addition, the high cost of LED is the most important obstacle, and the immature supply market itself, the imperfect market construction, and insufficient consumer awareness have all hindered the popularization of LED lamps in various fields.
Based on this, Zhang Xiaofei proposed solutions: improving light efficiency, large-scale production, reducing LED production costs; improving LED packaging technology, improving light extraction efficiency, and solving heat dissipation problems of high-power LEDs; improving the quality of chip epitaxial materials and improving internal quality Quantum efficiency and luminous efficiency, develop new technologies to improve the color temperature and color rendering coefficient of LEDs.
Finally, Zhang Xiaofei pointed out that the lighting consumption demand presents nine major trends, functional subdivision, luxurious style, rich colors, high technology, multi-functional, energy-saving and environmental protection.

Deputy Director of Xi'an Optoelectronic Technology Industry Development Center Chai Jie: Overview of Semiconductor Lighting Project in Xi'an
Chai Jie introduced the application and application progress of semiconductor lighting engineering in Xi'an. In 2010, Xi'an Aerospace Base, High-tech Zone, Qujiang New District, City Wall Scenic Spot, Datang Furong Garden and Greenland Plaza will be on road lighting and landscape lighting. Use 5327ç› and 63030ç› respectively. The next important task of Xi'an in promoting semiconductor lighting is to ensure the quality and quantity of the pilot work tasks, highlight the characteristics of Xi'an semiconductor lighting demonstration project, cluster development, and improve the industrial chain.
Chai Jie said that in order to build a semiconductor lighting demonstration project with Xi'an characteristics, the LED application demonstrations of the World Expo, the Daming Palace, the city wall and other urban scenic spots, which highlight the image of Xi'an tourism city, should be strengthened, and at the same time, with Xi'an The city's rapidly developing concept of Internet of Things and other concepts combine to create a smart control road lighting demonstration.

Mu Yijing, General Manager of Xi'an Liming Electronic Technology Co., Ltd.: How to improve the quality of LED whole lamp system
Mu Yijing discussed how to improve the quality of LED whole light from the perspective of the optical quality of LED road lighting. Mu pointed out that the high-pressure sodium lamp has optical defects: when the light source is 120lm/w, the whole lighting effect is only about 80lm/w. The road surface efficacy is only 50lm/w~60lm/w. Light outside the practical road surface not only contributes to road lighting, but also causes light pollution. In addition, the presence of longitudinal uniformity of the high pressure sodium lamp achieves difficulties and optical disadvantages. In contrast, the light source characteristics of LED urban road lighting: color temperature selection, high color rendering index, is conducive to improving urban driving safety, using secondary optical design will easily meet the vertical uniformity requirements of urban road lighting standards, In two-way six-lane and eight-lane lighting, the pole is only 10m long enough.
Mu Yijing proposed several measures to improve the light efficiency of LED city road lighting: 1. Select high-efficiency LED tube; 2. Select LED tube with higher luminous flux at the same junction temperature; 3. Choose longer life at the same junction temperature. LED tube; 4, secondary optical design to avoid the use of reflective principle; 5, to avoid multiple light transmission barriers; 6, secondary optical design light distribution on the effective road surface and non-effective road surface ratio, is to improve the road surface brightness and illumination One of the important links; 7. In the secondary optical design, in the case of the same road lighting standard in the effective road surface, the light ratio at the far and close distance is also one of the important links to improve the illumination and brightness of the road surface.

Philips Lumileds Asia Marketing Director Zhou Xuejun: LUXEON Rebel - setting a new benchmark for LEDs quality
According to Zhou Xuejun, according to Philips Lighting, the proportion of LED lighting in 2008 is about 7% of global lighting, and it is estimated that it will reach 75% in 2020. Philips Lumileds will have more than $100 million in research and development investment this year. At present, the development of LED lighting is very fast, but LED lighting applications still face many challenges, focusing on the four aspects of light quality, performance, reliability and simplicity.
Zhou Xuejun introduced the latest Lumiramic patented fluorescence technology used by Philips Lumileds' new LUXEON Rebel 2700K and 3000K warm white light products. Its white light distribution can reach 1/16 of ANSI BIN, and Philips Lumileds' vision is to make the lighting industry completely Get rid of the troubles of BIN. After introducing the latest 300+ lumens high-light products LUXEON Rebel ES, which was specially designed for outdoor lighting, Zhou Xuejun also expressed his optimistic view on the prospect of AC LED. Philips Lumileds will soon launch its own unique AC LED products. In the field of LED backlighting, he introduced the high-power LED-based backlighting solution that is emerging due to its advantages in color stability and reliability. He also mentioned that the company's LUXEON Rebel LEDs have passed the US Energy Star certification and LM-80 test as early as last year.
