Absolute vs. relative efficiency: How efficient are blue LEDs, actually?
Category: Environment Hits: 8
The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study has found that the assumption of always perfect IQE is wrong: the IQE of an LED can be as low as 27.5%.Read more https://www.sciencedaily.com/releases/2023/05/230526183206.htm
