Abstract:
A curing light comprising:a wand adapted to be grasped by a human hand for use in positioning and manipulating the curing light, a light module on said wand, said light module including a secondary heat sink, said secondary heat sink being configured to assist in heat dissipation, said secondary heat sink having a first and a second mounting platform, said first and said second mounting platforms being arranged with respect to each other at an angle &thgr;, said angle &thgr; being less than 180 degrees, first light emitting semiconductor chip module mounted on said first mounting platform, a second light emitting semiconductor chip module located on said second mounting platform, and each of said first and said second chip modules including a primary heat sink, a light emitting semiconductor chip affixed to said primary heat sink, and a cover; wherein mounting of said primary and secondary chip modules on said first and second mounting platforms at an angle &thgr; with respect to each other causes light from said first and said second chip modules to overlap in an overlapping light beam that creates an overlapping light footprint that has increased light density compared to only one of said chip modules emitting light.
