A DENTAL LIGHT IRRADIATION DEVICE

摘要

A dental light irradiation device (1) which has a light emitting diode (15) and a heat sink (16) for dissipating heat generated by the LED. The heat sink (16) is formed of a composition which includes a polymer and a filler. The filler provides the composition with increased thermal conductivity relative to the polymer alone. The invention helps maximizing the convenience in handling of dental light devices.
