ABSTRACT:
A cooling system suitable for use with a light curing device includes a forced air unit, such as a diaphragm pump, a fan, or an eccentric cam blower that is disposed remotely from the hand-held portion of the light curing device, such as, within a power plug of the light curing device. Tubing electrically and pneumatically interconnects the power plug and the hand-held portion of the light curing device. Air blown by the forced air unit through the tubing is directed to the hand-held portion of the light curing device about a heat sink that is disposed therein. The circulating air displaces hotter air surrounding the heat sink, thereby lowering the ambient temperature within the light curing device.
