Mu Yijing: How to improve the quality of LED whole light system
On August 23, 2010, sponsored by Gaogong LED, Xi'an High-tech Industrial Development Zone Management Committee, Xi'an Optoelectronic Technology Industry Development Center and Xi'an Technology Property Exchange Center, 2010 LED Illuminated China Tour - National Tour Survey and Industry Seminar The seventh seminar of the event was successfully held in Xi'an. 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.
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.
