Patent ID: 6988890

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 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, an elongate light transport device for transporting a focused light beam to a remote location for use in curing, said light transport device having a longitudinal axis, a plurality of light emitting semiconductor modules located on said heat sink, each of said semiconductor modules including a primary heat sink, a well in said primary heat sink, said well having a light-reflective wall, 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 in said well, a cover serving to protect said chip, said light-reflective wall serving to reflect at least some light emitted by said chip in a direction that is generally orthogonal to said light transport device longitudinal axis, at least some of said light emitting semiconductor modules emitting light in a direction that is generally orthogonal to said light transport device longitudinal axis as a result of being reflected from light-reflective walls of said wells, a reflective light collecting device which collects light emitted by said light emitting semiconductor modules traveling generally orthogonal to said light transport device longitudinal axis and reflects it in a new direction as an unfocused light beam traveling generally in the direction of said light transport device longitudinal axis so that it may strike a focusing lens, and a focusing lens which serves to receive an unfocused light beam from said reflective light collecting device and focus said unfocused light beam toward a light transport device as a focused light beam.
