LED lighting development goals: 2020 luminous efficiency 258lm/W

President Obama to actively promote green energy policies, claims $150 billion launched a 10 year green construction plan, encourage the development of clean energy, its vision to create the United States as the global benchmark for green technology powers. The development of Building (Zero Energy) is one of the goals of the U.S. government's energy policy...

2010 market warm white LED light emitting element efficiency is 93 lm/W, slightly less than 96 lm/W by the U.S. Department of energy development plan in the 11 edition, but higher than the 10 year development plan of the target for the 90 version of lm/W. U.S. Department of energy is expected to 2020 when the warm white LED light-emitting efficiency of 253 lm/W, for the market in 2010, the white light of the luminous efficiency of the LED luminous efficiency of 2.72 times. The United States Department of energy in 2011 version of the solid-state lighting development plan, set the warm white LED element OEM target price of $18 in 2010 from /klm to 2012 to $7.5 to /klm, 2015 and 2020 respectively to $2.2 and $1 in /klm /klm. In 2010 the market cold white LED light emitting element efficiency is 124 lm/W, less than 134 m/W for United States Department of energy development plan targets in the plan, expected in 2012 when the cold white LED light emitting element efficiency is up to 176 lm/W in 2015, increased to 224 lm/W, to 2020 reached 258 lm/W, as of 2010 the actual luminous products the efficiency of more than 2 times.

The program is expected to cool white LED component foundry prices from 2010's $13 /klm, down to $6 in /klm in 2012, a decline of up to $2 in /klm in 2015, to $/klm in 2020 and then fell to $1. Due to the technical development, enhance the luminous efficiency faster than expected, the U.S. Department of energy in 2011 development plan, for the warm white light LED element luminous efficiency, Leng Baiguang LED light emitting element efficiency of each annual target value compared with the previous version, and cut each year warm white LED element OEM price target.
