Abstract
A compact, high-efficiency, high-power, solid state light source, comprising a high-power solid state light-emitting device, a light guide having a proximal light-receiving end proximate the light-emitting device and a distal light-transmitting end spaced farther from the light-emitting device, and a mechanical light guide fixing device coupled to the light guide near its proximal end, to hold the proximal end of the light guide in position near the light-emitting device.
Claims23
An illumination device comprising:
- a high-power solid state light-emitting device having a flat package, the flat package comprising a structural window material encasing a light-emitting element of the light-emitting device on exposed top and side surfaces of the light emitting element such that the structural window material is disposed adjacent to and in contact with a light-emitting surface of the light-emitting element and has a flat face opposite the light-emitting surface, wherein the flat face directly light couples to a light guide;
- and
- the light guide comprising a light-receiving end and a light-transmitting end, wherein the light-receiving end is in contact with proximate to the face of the structural window material;
- wherein the structural window material comprises a ground dome lens having a flat top surface.
The illumination device according to clause 1, wherein the light guide comprises a single glass or plastic fiber.
An illumination device comprising:
- a high-powered solid state light-emitting device having a package, the package comprising a light-emitting element and a flat structural window material, wherein the light-emitting element defines a light-emitting surface and the flat structural window material is adjacent to and in contact with the light-emitting surface, wherein the structural window material encases the light-emitting element on exposed top and side surfaces is encased within the package such that the structural window material has a flat surface that directly light couples to a light guide;
- and
- the light guide comprising a flat light-receiving end and a light-transmitting end, wherein the flat light-receiving end is in contact with proximate to the flat structural window material;
- wherein the structural window material comprises a ground dome lens having a flat top surface.
