Luminous efficiency of 258lm/W in 2020, the US LED lighting development goal

Annual luminous efficiency lm/W, US LED lighting development target The luminous efficiency of warm white LED components on the market in the year is lm/W, which is slightly lower than the lm/W target set in the US Department of Energy's development plan, but higher than the annual development plan The set target lm/W. The U.S. Department of Energy expects that the luminous efficiency of warm white LED components will reach lm/W by the end of the year, which is twice the luminous efficiency of warm white LED components on the market. In the annual solid-state lighting development plan of the US Department of Energy, the target price for the foundry of warm white LED components has been reduced from USD/klm at the time of the year to USD/klm at the time of the year, and to USD/klm and USD respectively at the time of the year. /klm. The luminous efficiency of cold white LED components on the market in 2016 is lm/W, which is lower than the m/W target set by the U.S. Department of Energy’s development plan. In the plan, the luminous efficiency of cold white LED components is expected to reach lm/W by the year. When the time is increased to lm/W, it will reach lm/W by the year, which is more than twice the actual luminous efficiency of the product. According to the US Department of Energy's LED Lighting Development Plan, it is expected that the foundry price of cold white LED components will drop from USD/klm in the year to USD/klm by the end of the year, a decrease of .%, reaching USD/klm in the year, and then falling again by the end of the year. To USD/klm. Due to technological development, the rate of increase in luminous efficiency is higher than expected. In the annual development plan of the US Department of Energy, the luminous efficiency of warm white LED components and the luminous efficiency of cold white LED components have been set higher than the previous version. Annual target price for foundry of warm white LED components.
