Patent ID: 6971876

Claim:
A curing light comprising: a housing for housing components of a curing light, air space within said housing, at least one vent located on said housing, a secondary heat sink located within said housing, said heat sink having a proximal side, a radial periphery, and a distal side, a thermoelectric cooler to assist in heat dissipation located on said secondary heat sink proximal side, a fan located within said housing, said fan being capable of causing air to move past said thermoelectric cooler in order to improve heat dissipation, a plurality of light emitting semiconductor modules located on said heat sink, at least one of said light emitting semiconductor modules being located on said heat sink distal side, a plurality of said light emitting semiconductor modules being located on said secondary heat sink radial periphery, light from said light emitting semiconductor module located on said heat sink distal side traveling generally toward a light transport device which serves to transport light to a curing location, light from said light emitting semiconductor modules located on said heat sink radial periphery traveling generally orthogonal to a light transport device which serves to transport light to a curing location, each of said semiconductor modules including a primary heat sink, a semiconductor chip which emits light of a wavelength useful for curing light curable composite materials, said chip being affixed to said primary heat sink, a cover serving to protect said chip, a reflective light collecting device which collects light emitted by said semiconductor modules located on said secondary heat sink radial periphery and directs it as an unfocused beam toward a focusing lens, a focusing lens which serves to focus said unfocused light beam from said light reflective device onto a light transport device, and a light transport device for transporting said focused light beam to a curing location.
