Abstract
A light-emitting diode includes a PN junction light-emitting portion over a substrate; wherein the PN junction light-emitting portion includes an alternating-layer structure of alternating a strained light-emitting layer and a barrier layer, wherein the strained light-emitting layer with a component formula of GaInAsP, 0<X<1 and 0<Y≤0.05, and the barrier layer has a component formula of (AlGa)InP, 0.3≤a≤1 and 0<b<1; when a current of 350 mA flows through the PN junction light-emitting portion in forward direction, the light-emitting diode has an output power at least 202.2 mW.
