A lighting fixture comprising for use in an environment which requires protection from EMI/RFI emissions. The fixture comprises a body forming a light-emitting opening, lighting components including at least one lamp in the body, a lens covering the opening, and a conductive grid across the opening, the grid being separate from the lens, electrically connected to the body, and positioned between the lighting components and the opening. The grid is a conductive screen which covers the entire opening between the component area of the fixture and the light- emitting opening area of the fixture, thereby encasing the lamps in metal which prevents EMI and RFI from escaping outside the fixture.
Il s'agit d'un appareil d'éclairage utilisable dans un environnement nécessitant une protection antiparasites. Cet appareil comprend un corps formant un orifice électroluminescent, des éléments d'éclairage comprenant au moins une lampe dans le corps, une lentille couvrant l'orifice et une grille conductrice à travers l'orifice. La grille est séparée de la lentille, raccordée électriquement au corps, et placée entre les éléments d'éclairage et l'orifice. La grille est un écran conducteur qui couvre tout l'orifice entre la partie des éléments de l'appareil et la partie de l'orifice électroluminescent de l'appareil, ce qui enferme ledit appareil dans du métal et empêche les signaux parasites d'en sortir.
