ABSTRACT:
A surface-mountable light-emitting diode light source is described, in which the leadframe-bends toward the rear side of the package that are required for surface mounting lie within a transparent plastic molded body. Also described is a method of producing a mixed-light, preferably white-light source on the basis of a UV- or blue-emitting semiconductor LED. The LED is mounted on a leadframe, a transparent plastics molding composition is mixed with a conversion substance and possibly further fillers to form a molding composition. The leadframe is encapsulated, preferably by the injection-molding process, with the molding composition in such a way that the LED is surrounded on its light-exiting sides by the molding composition.
