Photo activation device of photosensitive composite materials used in dentistry has optic fibers associated with light emitting diodes in way that surface of diode is optically coupled with inlet surface of one or several optic fibers

摘要

A light concentration device (23') permits to combine in a point a light emitted from all emitting surfaces (25) of diodes (20). The device (23') includes optic fibers (23) associated with the light emitting diodes (20) in a way that the surface (25) of the diode (20) is adjusted optically with the inlet surface of one or several optic fibers (23).
