Lighting is very important to human’s life. In the last ten years, Solid-State-Lighting technology has made great improvement, and LED has been widely used in many application areas. This report mainly introduces the recent status, domestic and international situations and development trends of the Solid-State-Lighting technology, in seven parts: materials and chips, packaging, lighting systems, lighting applications, non-lighting applications, metrology and standards. The report is divided into two parts: general report for summary and special reports for details.
The luminous efficacy is no longer a limitation to the applications of LEDs, since the technology of materials and chips, packaging and application systems has made great improvement. Nowadays, Solid-State-Lighting industry is trying to reduce the cost, while offering more comfortable and higher quality of lighting. Intelligent and multi-functional lighting are also important. Solid-State-Lighting technology has also been used in agriculture, poultry breeding, medical applications and communications. Besides, in terms of metrology and standards, fundamental research on lighting standards is in urgent needs. Standardization of LED modules and universal interfaces has received more and more attentions.
