Abstract: A photo-curing device includes a light source for initiating the curing of a photo-curable material. The light source has light-emitting diodes, each emitting light in a determined wavelength range, the wavelength ranges of the LEDs overlapping partially so as to cover a continuous wavelength range that is broader than the wavelength range of each LED. An activation device is provided for selectively activating each LED.

Abstract: The invention relates to a photopolymerization device (100) comprising a polymerization light source (111) and optical means (113) for guiding and/or directing the light energy produced by said source towards a zone photopolymerizable material. The photopolymerization device (100) further comprises means (117, 118) for measuring the intensity of the light reflected by the material for polymerizing, and in that said intensity measurement means are in communication with processor and control means (300) for controlling the light source and responding to the intensity measurement to adjust automatically at least the duration of the illumination by the light source (111) as a function of the measured intensity of said reflected light.

Abstract: The invention relates to an electro-optical device for the photo-polymerization of composite material, and is used in particular in the dental field. The inventive device comprises a light source (2) which is defined by an LED or a group of LEDs. It comprises electrical power supply means consisting of a battery (4) which is associated with a direct current/direct current converter device (7) commonly known as a DC/DC converter, passive means (3) for the evacuation of heat, and a central management unit (5) for operating parameters of the light source for the definition of a determined photo-polymerization energy profile.
