Document Type and Number:
WIPO Patent Application WO2001080322
Kind Code:
A3
Abstract:
The invention relates to a high-radiance LED chip (1) comprising a radiation-emitting active region (32) and a window layer (2). In order to increase the radiant yield, the cross-sectional surface of the radiation-emitting active region (32) is smaller than the cross-sectional surface of the window layer (2), which is made available for disengaging the light. The invention also relates to a method for producing a lens structure on the surface of a light emitting component.
