ABSTRACT:
A dental curing light comprises an elongate hollow wand housing having a proximal first end, a distal second end, a light source disposed at the distal second end of the wand housing, and a heat sink disposed at least partially within the wand housing. The heat sink is in contact with the light source, and comprises a plurality of layers or regions comprising different materials. A first layer or region comprises a first material having a higher thermal conductivity than that of a second layer or region, while the second layer or region comprises a second material having a specific heat greater than that of the first layer or region.
