LED emitters and lighting fixtures with a vast array of new and established Chinese companies beginning to develop LED products and technologies that could be vital for the future of lighting.
The majority of the lighting companies seen at the Guangzhou International Lighting Fair are commercialising standard products which may or may not be suitable for the European market in terms of performance or safety standards, however there is definitely significant progress being made by these home grown companies. The Chinese lighting market is expanding significantly driven by Government support for energy efficient and green lighting projects. International market research
states that the Chinese market will become the largest global lighting market by 2017 therefore it’s vitally important the European lighting community engages with their Chinese counterparts to share expertise and technology know-how in order to access this market. Finally, the latest OLED roadmaps highlight 2011 and 2012 will be defining years for promises being made about the robustness and performance of OLED lighting fixtures. If the technology cannot be made in volume, low cost and reliable compared to traditional light sources or even high brightness LEDs by the end of 2012 I think the opportunities for OLEDs to gain significant market share could be lost.
