About the Conference

The "First International Conference on White LEDs and Solid State Lighting (White LEDs-07) is being held from the 26th to the 30th of November 2007. The chairman of the conference, which is being organised by the Illumination Engineering Institute of Japan (IEIJ), is Professor Tsunemasa Taguchi of Yamaguchi University. The conference is being supported financially by a Grant-in-Aid from the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT).

The comprehensive four day programme of invited and contributed talks and poster sessions, covers all aspects of emerging LED and OLED solid state lighting technologies including device materials, architecture, packaging and manufacture, device performance, phosphors and colour quality, market analysis and projections, and mainstream lighting and specialist applications.

Dr Devonshire's talk "The Competitive Technology Environment for LED Lighting" will compare and contrast the performances of light sources in each of the three major branches of light source technology, namely: thermal (e.g., halogen); discharge (e.g., fluorescent); and solid state lighting (e.g., LED). Although White-LED lighting has made rapid progress in recent years the performance of lamps in the two established lighting technologies, thermal and discharge, has also continued to advance significantly. The lighting market itself is also changing with increasingly restrictive performance and environmental regulations coming into force worldwide, and concerns about the usage patterns of artificial lighting leading to an increasing emphasis on the control of lighting. The talk will analyse these factors, and others, to provide an overview of the true competitive nature of the market.
