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.
Claims24
An endoscope comprising:
- a) a high-power solid state light-emitting device having a light emitting region of a semiconductor chip with a lens and coupling gel removed, and
- b) a fiber optic light guide comprising
- a light-receiving end and a light-transmitting end wherein the light receiving end is placed directly against the light emitting region of the light-emitting device, said light-receiving end matching the size and shape of the light-emitting region.
An illumination device comprising:
- a) a high-power solid state light-emitting device having a light emitting region of a semiconductor chip with a lens and coupling gel removed, and
- b) a fiber optic light guide comprising
- a light-receiving end and a light-transmitting end wherein the light receiving end is placed directly against the light emitting region of the light-emitting device, said light-receiving end matching the size and shape of the light-emitting region.
