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.
Claims17
A method of producing an LED light source, which comprises the following steps:
- forming a recess with a planar bottom face in a basic body;
- mounting an LED on the bottom face;
- filling the recess with a defined amount of a transparent material containing converter material;
- providing a lens with a concave underside;
- while the transparent material is still in a liquid form, inserting the lens with the concave underside into the transparent material;
- and
- curing the transparent material.
