There is a significantly decline in costs of LED product applications particularly commercial LED light such as high power LED flood light and constantly improve on cost-effective : the introduction of new technology makes the upstream epitaxial wafers, chip technology increasingly matures , significantly improving the efficiency of commercial high power LED flood light and other commercial and household LED light , while a large amount of new capacity into market lead to the intensified competition. The costs of raw material made into the LED light and prices are likely to drop sharply .

The growth in Luminous efficiency is steadily by an average of 10% to 15 % : high brightness LED luminous efficiency is rising，take the U.S. Cree ‘s for example, white LED luminous efficiency of commercial LED lighting products including high power LED flood light is 139lm / Win 2009, the company has exhibited white high power LED flood light and other LED products whose luminous efficiency is up to 208lm / W on March 2013, the compound growth rate is 10.6%.

The decrease in the prices of high power LED flood light and other outdoor and indoor LED lighting products is by average of 20% to 40% : take the LED bulbs ( replaces 60W incandescent ) for example , , the global average price of LED bulbs is $ 21.9 as on August 2013  , with an average annual decline of 28.7% ~ 29.9% ; the average price of Japan LED bulbs is $ 21.5 , with an average annual decline of 30% to 36.4% .

The decline in costs of raw material and lower prices is conductive to the expansion of market capacity of LED industry，the decline in the costs of main raw material provide a price cut for high power LED flood light and other commercial and household LED application products and accelerate the development of LED product applications, while accelerating LED product’s market and the commercialization process .Browsing http://www.lead-lighting.com/products/sid125-1.htm for more information about high power LED flood light.

Why we have been concerned about LED lighting lies in its pretty large market size. The existing lighting including residential lighting , street lamps , etc., is expected to replace with LED ceiling light and other household and outdoor LED lighting. Coupled with active support of governments,the “green action ” conversing to green LED lighting is active day by day .

There are many countries focusing on LED ceiling light and other indoor and outdoor LED lighting , especially in Korea. South Korean Ministry of Knowledge Economy estimate that the growth rate average of LED ceiling light and other interior and exterior LED lighting market will by 30 percent, the market size of $ 21.4 billion in 2008 will expand to approximately $ 100 billion in 2015 . Facing with this huge market,the Korean government introduced a policy aimed at improving the competitiveness of Korea.Browsing http://www.lead-lighting.com/products/bid14-1.htm for more information about LED ceiling light.
