Abstract
A lighting apparatus for dental purposes having plurality of light sources supported on semi-conductor bases, which are mounted on a substrate is provided. The lighting apparatus includes a reflective over surface encircling the light sources which reflects visible light. The lighting apparatus may be deployed in a light hardening device as a light source unit with the emitted light beams being conducted, in particular, by a prismatic body, to a light guiding conduit.
