High radiance LED chip and a method for producing same |
摘要 |
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.
