Abstract
A light source suitable for surface mounting onto a printed circuit board. The light source includes a planar substrate with a centrally positioned aperture. A light emitting diode is mounted on a metallic layer covering the bottom of the aperture, and is encapsulated by a transparent encapsulant material. The metallic layer provides a thermal path for heat generated by the light emitting diode.
Claims16
A light source comprising:
- a substrate having opposing first and second surfaces, the substrate defining an aperture extending between the first and second surfaces,
- a platform covering an opening of the aperture adjacent the first surface,
- a light emitting diode mounted on the platform within the aperture, and
- a transparent encapsulant material encapsulating the light emitting diode in the aperture.
A light source as claimed in claim 2, wherein the platform extends beyond the opening of the aperture over the first surface.
A method of manufacturing a light source comprising:
- providing a substrate with opposing first and second surfaces,
- plating a first surface of the substrate with a metallic layer,
- drilling a hole through the substrate from the second surface up to the metallic layer on the first surface such that the metallic layer provides a platform covering the opening of the aperture adjacent the first surface,
- mounting a light emitting diode on the platform within the aperture, and
- encapsulating the light emitting diode in the aperture with a transparent encapsulant material.
