Patent ID: 7581846

Claim:
A light weight, hand held curing light system useful for curing light activated composite materials comprises: a light source housing comprising at least one light source mounted on at least one heat sink for drawing heat away from said at least one light source, said at least one heat sink comprising: a thermally conductive housing having an open end, a closed end, and a substantially hollow interior, said thermally conductive housing is substantially contained in the light source housing; a capping device comprising a formation for compression fitting in the open end of the thermally conductive housing; and at least one phase change material, undergoes substantially reversible phase changes, that partially fills said conductive housing; and said at least one light source mounted on the closed end of said thermally conductive housing; wherein said curing light system has a power supply locatable on said light source housing, said power supply serving to provide electrical power to said light source.
