Light emitting diode component
First Claim
1. A light emitting diode component, comprising:
- a light emitting semiconductor structure disposed on a growth substrate, the light emitting semiconductor structure having a top surface, anda micro-optical multilayer structure arranged to guide light out from said top surface of the light emitting semiconductor structure, said micro-optical multilayer structure comprising a plurality of layers, wherein an i+1;
th layer is arranged on top an i;
th layer in a sequence as seen from said semiconductor structure, wherein a refractive index, ni, of the i;
th layer is greater than a refractive index, ni+1, of the i+1;
th layer wherein the value of i is selected from the set of positive integers, wherein a thickness of the i+1;
th layer is greater than a thickness of the i;
th layer, wherein the thicknesses of the i+1;
th layer and the i;
th layer are on the order of hundreds of microns, and wherein the growth substrate is disposed between the multilayer structure and the light emitting semiconductor structure.
