Lighting Fixture with EMI/RFI Electrically Conductive Shielding Grid
First Claim
1. In a room-surface-securable luminaire including a body forming a light-emitting opening, lighting components having at least one lamp in the body, a lens covering the opening and having an inner surface, and a conductive grid connected to the body and extending across the opening to prevent electromagnetic interference from radiating from the luminaire during its emission of light, the improvement comprising the conductive grid being a separate structure from the lens positioned adjacent to the lens inner surface thereacross.

Abstract
A lighting fixture 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.

19. A luminaire securable with respect to a room surface, including:
-
a luminaire body forming a light-emitting opening, the body being mounted to a ceiling; lighting components including at least one lamp in the body; a lens having an inner surface covering the opening; and a conductive grid between the lighting components and the opening, the grid being a separate structure from the lens, electrically connected to the body and positioned adjacent to the lens inner surface thereacross and extending over the opening, whereby the grid prevents electromagnetic interference from radiating from the luminaire during its emission of light therefrom.
