High-power LED is to improve the brightness of the only way to replace modern lighting. Using high-power LED lighting has many advantages, and disadvantages. How to make the high-power LED is the key at the same time, this high-power LED lamps for lighting products made with more traditional, but also on the high-brightness LED applications in lighting and discuss the field.

Keywords: High power LED, high power, LED

First, the development of high-power LED LED from the history and potential applications to every 10 years since the birth of brightness by 30 times, 10 times the price down rapidly. Ordinary high-brightness white led now reached 100 lm / W level, 80 lm / W white LED high-power LED market has officially entered. In monochromatic light, the red, yellow, blue, green light effect also has been renewed recorded as a new type of high-power LED lighting products use high-power LED and more about the prices of cheaper, high-power LED gradually attracted people's attention and expectations.

Currently high-power LED applications were distributed in various diverse industries, including instructions, display, backlight and lighting. High-power LED lighting is the most promising sectors, with high-power LED light effect the continuous improvement and continuous cost reduction, its share in the lighting market will be growing. Near future high-power LED lighting market entry to replace the current lighting is widely favored. Liang-Hui Chen Chinese Academy of Engineering academician, according to forecasts, China in 2005 and 2015, the semiconductor light energy can be accumulated 400 billion kWh of electricity, for the users to reduce 260 billion yuan in electricity bills, and create 150 billion yuan output value, solve the one million population in employment.

High power LED energy saving per year will exceed the annual power generation of Three Gorges power station! In the context of increasingly scarce energy resources, use of high-power LED energy-saving features, the development of high power LED lighting is the world's energy problems on a positive response.

Second, high power LED light source characteristics and comparison with other, LED is a real "green light." In the lighting industry, will be high-power LED light source with the traditional comparative analysis of some aspects of high-power show can not substitute: LED as a light source for illumination has the following advantages:

1, power consumption is low, only about 80% of the power consumption of ordinary light.
2, long life, can light 50,000 hours continuous.

3, can produce any color at any angle and high-power LED

But the high-power LED is also inadequate, as in no real white LED. Currently produce white light LED, the color rendering index of about 80. For some color resolution for high places can not. Compared with the incandescent lamp still has a gap, LED high power prices were too high, one-time into a larger, comprehensive cost considerations from many occasions to use LED or significant cost savings
