Scientists succeeded in directly observing how LECs -- which are attracting attention as one of the post-organic LEDs -- change their electronic state over time during field emission by measuring ...
Researchers have demonstrated nanomaterial-based white-light-emitting diodes (LEDs) that exhibit a record luminous efficiency of 105 lumens per watt. Researchers have demonstrated nanomaterial-based ...
(PhysOrg.com) -- Researchers from the Nichia Corporation in Tokushima, Japan, have set an ambitious goal: to develop a white LED that can replace every interior and exterior light bulb currently used ...
The luminous efficiency for LED lighting has now risen to 100-150lm/W and is expected to keep rising to 200lm/W in five years and to 220lm/W in 2020, according to Solid State Lighting (SSL) Fellow ...
Taiwan's Ministry of Economic Affairs (MOEA) on July 1 brought into force a required minimum luminous efficiency of 75lm/W for indoor LED white-light bulbs and 70lm/W for indoor LED yellow-light bulbs ...
