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, and said secondary heat sink having a longitudinal axis, said secondary heat sink having a first, a second and a third mounting platform thereon, each of said first, second and third mounting platforms being generally planar, said first, second and third mounting platforms being arranged with respect to each other at an angle &thgr;, each of said first, second and third mounting platforms being arranged at an angle &phgr; with respect to said longitudinal axis of said secondary heat sink, a 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 a third light emitting semiconductor chip module located on said third mounting platform, each of said first and said chip modules including a primary heat sink, a light emitting semiconductor chip affixed to said primary heat sink, and a cover covering said chip; wherein light emitted by said chips converges in an overlapping light beam that creates a light footprint.
