CA 2245748

A luminaire to illuminate an article to be visually inspected for surface defects includes a housing having an opening in a forward face thereof. At least one elongate light source is accommodated by the housing. At least one linear reflector is also accommodated by the housing. The at least one linear reflector has at least one forwardly directed, angled reflective surface that directs light emitted by the at least one elongate light source such that the luminaire projects light onto a specular surface of an article being inspected resulting in a plurality of laterally, spaced images of the at least one elongate light source being reflected by the specular surface.

Cette invention concerne un appareil d'éclairage pour éclairer un article à soumettre à un examen visuel de surface, comprenant un boîtier à face avant ouverte, au moins une lampe de forme allongée fixée dans le boîtier, au moins un réflecteur également logé dans le boîtier et comportant au moins une surface réfléchissante orientée vers l'avant de manière à concentrer la lumière émise par la ou les lampes sur la surface de l'article à examiner afin que celle-ci réfléchisse plusieurs images séparées de la ou des lampes.
