Abstract
Disclosed is a lamp apparatus designed for both bleaching teeth and curing dental restorative materials. Both bleaching and curing modes of operation may be used in at least three different power levels designated as boost, ramp, and normal. The lamp apparatus contains a incandescent xenon-halogen bulb and a dichroic reflector which focuses filtered visible light on the end of a flexible light guide which is part a handpiece for directing the transmitted light by the light guide to a tooth being treated. The lamp apparatus employs a slave microprocessor in a control panel mountable at different positions on a housing for the xenon-halogen bulb and a master microprocessor within the housing which is detachably connected to the slave microprocessor.
