发明名称 Optoelectronic component and method for producing it
摘要 An optoelectronic component having a basic housing or frame ( 12 ) and at least one semiconductor chip ( 20 ), specifically a radiation-emitting or -receiving semiconductor chip, in a cavity ( 18 ) of the basic housing. In order to increase the efficiency of the optoelectronic component ( 10 ), reflectors are provided in the cavity in the region around the semiconductor chip. These reflectors are formed by virtue of the fact that a filling compound ( 28 ) filled at least partly into the cavity ( 18 ) is provided, the material and the quantity of the filling compound ( 28 ) being chosen in such a way that the filling compound, on account of the adhesion force between the filling compound and the basic housing, assumes a form which widens essentially conically from bottom to top in the cavity, and the conical inner areas ( 30 ) of the filling compound serve as reflector.
