LED solid-state lighting, infrastructure construction is a major task in the future

'To build new infrastructure for solid-state lighting, for technical staff is a major task in the future'. University graduate institute of technology study of Japanese mountain pass while the professor taguchi often are, (the '2006 LED technology seminar LED技术研讨会2006) 'Said. Scheduled to realize LED oriented theory limit efficiency 300 lm/W 2020, taguchi in motivating young researchers and technicians for further research and development at the same time, shows the new infrastructure to build lighting area road map ( 路线图) , hope in material and device technology leading Japan to participate in the cooperation and become a leader. Taguchi pointed out that, as a road map of high output, the goal is to achieve 100 before 2010 lm/W, in 2015 before 200 lm/W, in 2020 before 300 lm/W. In addition, improve the quality of the color rendering of the light and ensure safety and so on, is also necessary to implement solid-state lighting using LED. Taguchi said, lighting the theoretical research of solid technology is 'a difficult and important field. Because leds on the luminosity distribution Angle dependence, so can't use incandescent light bulbs and fluorescent lighting engineering were analyzed, and the need to have a new theory of point light source. In addition, with LCD back light is different, in terms of lighting light objects, color is very important, in the use of red ( R） , green, G） , blue, B） Color phosphor white leds emit white fluorescent type mode, object more beautiful. Taguchi said: 'now have a very good fluorescent body. 'And lit a trial in April, the use of R15 96 RGB color fluorescent type white LED lights. About the LED, scheduled for August is released to the international conference. In addition, taguchi introduced in 2007 in Tokyo on November 26 ~ 30 Pacific hotel ( Le Meridien Pacific Tokyo, shinagawa) , to discuss the use of LED lighting field 'the first white LED solid-state lighting international conference'. In the field of international conference held in Japan for the first time. The organizers for the Japanese lighting academy, coordinated external academic organization for Japan photoelectric conversion 125 committee. Details and papers published guidelines in July after reservation on lighting academy website. （ Reporter: onishi male)
