High-power LED characterization
The efficiency decreases at high current, is a major problem to solid state lighting. This problem is called “droop”. The definition of droop is the loss of efficiency at high power. In order to keep the electrons in this region, the feature have an electron blocking layer, Gan barriers and active r...
