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.
