Patent ID: 7306960

Claim:
A method of fabricating a lens structure on the surface of a light-emitting component, wherein the light-emitting component comprises a radiation-emitting active region of lateral cross-sectional area F L and a radioparent window layer disposed after said radiation-emitting active region in the direction of radiation and having a refractive index n S , and which, for purposes of the decoupling of light, has a lateral cross-sectional area F C and comprises a decoupling surface adjacent a medium having the refractive index n M , the cross-sectional area F L of the radiation-emitting active region being smaller than the cross-sectional area F C of the decoupling surface, in accordance with the relation: F L ≤ ( n m / n S ) 2 · F c characterized in that on an outer surface of said light-emitting component through which light is intended to exit or pass, said lens structure is shaped by means of a milling or sawing tool or an etching process.
