Abstract

Apparatus has a light source including an electric discharge lamp and reflector connected by an optical cable to a light outlet. The fiber optic has a bundle of fibers. One end of the cable has a plate for positioning it at the focal point of reflector. A filter is between the plate and the reflector.

Description

La présente invention concerne un appareil pour polymériser desThe present invention relates to an apparatus for polymerizing

compositions dentaires photopolymérisables par action de la lumière.  light-cured dental compositions by the action of light.

Les inconvénients des appareils à diode émettrice ou à laser de l'art  The disadvantages of emitting diode or art laser devices

antérieur sont complexes et onéreux.  anterior are complex and expensive.

Pour pallier ces inconvénients, la demanderesse a eu l'idée d'utiliser une  To overcome these drawbacks, the applicant had the idea of using a

lampe à microdécharge utilisée pour des accessoires automobiles.  microdischarge lamp used for automotive accessories.

L'invention consiste en un appareil caractérisé en ce qu'il est composé d'un générateur de lumière utilisant une lampe à microdécharge équipée d'un réflecteur et alimentée par un appareillage électronique, un cordon conduisant îo la lumière depuis la lampe à microdécharge jusqu'à un embout de sortie de lumière.  The invention consists of an apparatus characterized in that it is composed of a light generator using a micro-discharge lamp equipped with a reflector and supplied by electronic equipment, a cord leading the light from the micro-discharge lamp to '' to a light output tip.

On comprendra mieux l'invention à l'aide de la description qui suit faite  The invention will be better understood using the following description made

en référence aux figures annexées suivantes: * Figure 1: vue générale d'un appareil selon l'invention, * Figure 2: vue en coupe d'une lampe utilisée dans l'appareil selon  with reference to the following appended figures: * Figure 1: general view of a device according to the invention, * Figure 2: sectional view of a lamp used in the device according to

l'invention, et présentée ouverte.  the invention, and presented open.
