Abstract

A curing device for curing dental materials by light-induced polymerization has a supply station and a hand-held apparatus including a light source. A detachable cable connects the hand-held apparatus to the supply station. An output control device controls the light source in order to ensure a uniform light intensity, wherein the output control device has a preset nominal output. The output control device includes a control FET. The cable is connected within the output control device. The output control device prevents switching on the curing device or emits a warning signal when the nominal output requires a voltage, surpassing a control bias voltage minus a potential difference of the control FET, or a corresponding current.
