U.S. President Barack Obama to actively promote green energy policy, advocates launched a U.S. $ 150 billion investment in 10 years of green building program to encourage development of clean energy, and its vision to build the U.S. as the global benchmark for green technology power. Development of zero-energy buildings (Zero Energy Building) for the U.S. government’s energy policy objectives …
2010 warm white LED devices on the market for the luminous efficiency 93 lm / W, slightly lower than the 11 version of the U.S. Department of Energy Development Plan set out 96 lm / W target, but higher than the 10-year version of the development plan targets 90 lm / W . U.S. Department of Energy 2020 is expected to warm white LED luminous efficiency of device 253 lm / W, the market for the 2010 warm white LED luminous efficiency of 2.72 times the component.
U.S. Department of Energy in 2011 edition of solid-state lighting development plans, setting warm white LED OEM components from the 2010 target price of $ 18 / klm, from 2012 down to $ 7.5 / klm, 2015 and 2020 were reduced to $ 2.2 / klm and $ 1 / klm.
On the market in 2010 cold white LED luminous efficiency of device 124 lm / W, lower than the U.S. Department of Energy Development Plan set 134 m / W target, plan, expected in 2012, when the cold white LED luminous efficiency of 176 lm components / W, in 2015 to 224 lm / W, up to 2020, when 258 lm / W, the actual luminous efficiency of the product in 2010 more than 2 times.
The plan is expected to cool white LED components from the OEM price of 2010 $ 13 / klm, from 2012 down to $ 6 / klm, a drop of 53.8% in 2015 up to $ 2 / klm, lower and lower by 2020 to $ 1 / klm.
As the technology development, luminous efficiency faster than expected, the U.S. Department of Energy Development Plan in 2011, set warm white LED luminous efficiency of components, cold white LED luminous efficiency of each component compared with the previous version of the annual target upgrade and downgrade the annual warm-white LED target price OEM components.
