In the 2011 lighting development plan, the US Department of Energy (DOE) plans to increase the luminous efficiency of the white LED components and the luminous efficiency of the cool white LED components by the previous version, and reduce the annual warm white LED component OEM. target price.
In 2010, the luminous efficiency of cool white LED components on the market was 124 lm/W, which is lower than the target of 134 lm/W set by the US Department of Energy. In the plan, it is expected that the luminous efficiency of cold white LED components will reach 176 lm in 2012. /W, increased to 224 lm/W in 2015 and 258 lm/W by 2020, more than twice the actual luminous efficiency of products in 2010.
The plan expects the price of cold white LED components to be reduced from US$13/klm in 2010 to US$6/klm in 2012, a drop of 53.8%, and US$2/klm in 2015, and will fall again by 2020. To $1/klm.
In addition, the luminous efficiency of warm white LED components on the market in 2010 was 93 lm/W, which was slightly lower than the target of 96 lm/W set by the US Department of Energy's 11th edition development plan, but higher than the target of 90 years of the 10-year version development plan. /W. The US Department of Energy expects that the luminous efficiency of warm white LED components will reach 253 lm/W by 2020, which is 2.72 times the luminous efficiency of warm white LED components on the market in 2010.
In the 2011 version of the solid-state lighting development plan, the US Department of Energy's target price for warm white LED components was reduced from US$18/klm in 2010 to US$7.5/klm in 2012, and dropped to 2015 and 2020 respectively. 2.2 USD/klm and 1 USD/klm.
