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.

Claims

1-25. -25. (canceled)

26. An illumination device comprising:

a high-powered solid state light emitting device comprising an array of light emitting semiconductor chips with lens and coupling gel removed; and

a light guide comprising a light receiving end and a light-transmitting end, the light-transmitting end in direct contact with the array of light emitting semiconductor chips, said light-receiving end matching the size and shape of the array of the light-emitting semiconductor chips.
