According to a survey released by the Japanese market agency Fuji Keizai on March 31, the global light source market (including visible light, ultraviolet light, LED and semiconductor laser) fell by 0.6% to 3 trillion in 2007. 8,15 billion yen. Among them, the visible light (including white heat lamp, fluorescent lamp, etc.) accounted for 79.4%, the ultraviolet lamp was 1.3%, the LED was 14.0%, and the semiconductor laser (semiconductor laser) was 5.2%.
According to the report, in the LED (including visible light LED, infrared LED and ultraviolet LED), due to the economic downturn and low consumption, the inventory of enterprises is difficult to eliminate. Therefore, the demand in this market decreased by 8.3% to 100 billion in 2008. It also fell 4.8% year-on-year to 535.2 billion yen.
The report also pointed out that the global market size of LED in 2009 is expected to be reduced by 6.4% year-on-year to around 500.9 billion yen, but it is expected to turn into positive growth after 2010. The Fuji economy also predicted in the report that the global LED market demand is expected to increase by 11.6% to 111.6 billion in 2008; the amount is expected to increase by 18.9% from 2008 to 636.3 billion yen.
