Countries in Europe and the America pay early attention to indoor energy saving LED lighting, as early as 90s in the last century the United States Environmental Protection Agency introduce a identification system for energy-efficient: EnergyStar, to label the products meet the energy efficiency standards with a green five-pointed star, and enter the catalog of United States Environmental Protection Agency for promoting.
But over the past two years' rapid development of LED technology, LED light-emitting efficiency progress a lot, LED can already replace the traditional light sources in many places, in particular the emergence of high-power LED, it has accelerated the speed of LED light sources to replace traditional lighting, also makes the LED for large area indoor lighting applications become more realistic. Along with the industry continues growing, and high-power LED will be reduced a lot on the price, coupled with the strong national policy guidance, the future of LED Interior lighting will enter the main light source of the lighting market.
According to the statistics of Strategies Unlimited, the development of LED interior lighting will be exponential growth within the next five years. It is estimated that by 2011, its output will be up to several billions dollars. LED interior lighting is a very huge market, Especially the European Union banned incandescent in 2009, as well as the continued promotion of energy conservation issues, bring an enormous market opportunity and optimistic outlook for LED interior lighting. From the Blueprint of National semiconductor can know that LED entered the general lighting market in 2007, and by 2010, the white LED will replace part of fluorescent lamps and enter the main market including home lighting.
Faced with such huge market opportunity, LEDKE Technology Co., Ltd (www.ledke.com) launched several LED interior lighting to the market, such as the LED tube lighting, LED ceiling lamp, LED par light, LED spot lights and so on, LEDKE started the layout of LED home lighting. All the signs show that with the improvement of LED technology, especially the cooling technologies of high power white LED, domestic firms come to realize the huge market of indoor lighting, and many companies layout to seize the market opportunities.
The application for indoor LED light sources require high light efficiency, low thermal resistance, color temperature controllability, good color rendering, long lifespan, low-cost, integrated design and so on. At present, there is no problem on the basic technical aspects of LED indoor lighting, compare with traditional fluorescent lighting, LED already has advantage of energy saving.
However, due to high cost issues, the promotion is still difficult; In addition, as many places are traditional lamp structure, and if replaced by LEDs, but also need replace the lamp structure.
The suggestion for LED indoor lighting is the initial purchase cost can be about 5 ~ 10 times of the traditional lighting. The light source accounted a very large proportion of the LED lamp cost, so reduce the cost of high-power LED light source is the key to reduce the lamp price. Along with technology improving and the cost of falling, the promoting for interior LED lighting will be much easier than before.
