ABSTRACT:
A mains-operated device for curing by light polymerizable dental material has a housing with a light guide and a cooling fan. A halogen light source, including a reflector and a spiral-wound filament, is positioned in the housing and emits light through the light guide. A control device is connected to the light source. The reflector is positioned at an end of the filament remote from the light guide. The reflector is transmissive for infrared radiation. The reflector is positioned in the cooling air flow of the fan. The control device supplies the filament with a voltage of 100 V to 240 V. The filament provides luminance of more than 750 cd.
