Abstract
A dental curing light includes a device body that efficiently conducts heat away from the light emitting diode (LED) portion of the curing light. The device body is one-piece body formed from a continuous seamless piece of thermally conductive material extending between a proximal end and a distal end. The one-piece body includes a gripping handle portion extending to the proximal end and a light-emitting head portion extending to the distal end. The one-piece thermally conductive body acts as a heat sink to efficiently conduct heat away from the LED dies during use. The one-piece body eliminates problems of multi-segmented curing lights that include one or more joints between adjacent segments. Eliminating joints increases thermal conductivity of the body, eliminates crevices where microbes can grow, and eliminates the risk of accidental separation if the curing light is dropped.
