United States Department of energy to support solid-state lighting 2020 LED lighting is expected to move towards the mainstream

President Obama's energy policy, the development of "the slogan shouted for cheap, clean and efficient energy, the development of zero energy building (Zero Energy Building) in order to improve the efficiency of energy use is an important part of. According to 2006 statistics, the United States accounted for ordinary residential lighting power consumption 11.6%, commercial building energy consumption 24.8%, the data show that the reduction of the energy consumption of lighting products, one of the necessary conditions for the development of zero energy buildings, so as to promote the solid-state lighting to improve the efficiency of energy use, the United States reached an important key to reducing greenhouse gas emissions.

At present, LED lighting in the United States has reached the standard of competition with the traditional lighting, the biggest problem is that the price is too high, OLED lighting is not yet reached the mass production stage. The United States Department of energy in February 2005 in San Diego on the basis of the results set until 2020, in order to improve the efficiency of solid-state lighting and years of development plans to lower its price target. Plan in 2020 pointed out that the cold white light LED average luminous efficiency is 219 lm/W, OEM price target is $1 per thousand lumens; efficiency is 127 lm/W OLED lamp, OEM price target for every thousand lumens of $6 or $80 per square foot.

Because of the development of the ultimate goal of solid-state lighting to replace traditional lighting has become widely used in daily life, so in addition to the above technical development goals, Solid State Lighting Development Planning Commission set up to 2020 market oriented development of solid-state lighting milepost, 2020 target market general level LED lamp luminous efficiency above 140 lm/W.
