Abstract
The invention concerns a light-emitting diode chip () comprising a radiation-emitting active region () and a window layer (). To increase the luminous efficiency, the cross-sectional area of the radiation-emitting active region () is smaller than the cross-sectional area of the window layer () available for the decoupling of light. The invention is further directed to a method for fabricating a lens structure on the surface of a light-emitting component.
