Abstract
A method and apparatus for curing photocurable dental materials involve a solid state light emitter and a source of electrical current connected to the light emitter. The source of electrical current provides a current to the light emitter that is sufficient to reduce the lifetime of the light emitter to less than 10 hours. The intensity of light from the light emitter is substantially increased and the apparatus can be conveniently disposed of after use on a single patient. A light guide that includes two conical optical surfaces collects light from the solid state light emitter and optionally directs the light to a third optical surface which has the shape of an elongated, curved tube.
