High radiance led chip and a method for producing same

摘要

The invention concerns a light-emitting diode chip ( 1 ) comprising a radiation-emitting active region ( 32 ) and a window layer ( 2 ). To increase the luminous efficiency, the cross-sectional area of the radiation-emitting active region ( 32 ) is smaller than the cross-sectional area of the window layer ( 2 ) 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.
