Abstract

The light source has an LED, preferably produced for the surface-mounting technique, embedded in a transparent material filling. A converter substance is integrated in the filling for the at least partial wavelength conversion of the light emitted by the LED. A lens is glued onto the transparent material filling. The material filling has a convex surface and the lens has a concave underside entering into a form fit with the convex surface of the material filling.
