Patent ID: 7182597

Claim:
An instrument for curing light-curable compounds comprising: a housing; a light emitting structure positioned in the housing and including a plurality of light emitting dies forming a generally planar array positioned on a generally planar substrate; the substrate being mounted on a base made of a thermally conductive metal; a heat sink thermally coupled with the base to direct heat away from the base and light emitting structure; a reflector configured for being positioned with the light emitting structure, the reflector being a tubular structure having open proximal and distal ends; the open proximal end of the reflector surrounding the die array generally at the plane of the substrate, the reflector further configured to capture light emitted from the die array at the proximal end and direct the light out of the distal end onto a light-curable compound, an adaptor having opposite ends and configured to interface, at one end, with the distal end of the reflector and to interface, at the other end, with an end of a light guide so that the light guide is directly coupled to the distal end of the reflector for directly transmitting light captured by the reflector onto a light-curable compound.
