Abstract: A ceiling light fixture for medical patient rooms and a method for the same. The fixture comprises a body which defines a middle region and two side regions along opposite sides of the middle region. A cover is movably attached to the body and includes a lens over at least the middle region. A graphics image is associated with the middle region and is substantially parallel to the lens. At least one graphics-light source is within the middle region and configured for illuminated display of the graphics image. At least one exam-light source is located within each of the two side regions.

Abstract: A ceiling-mounted troffer-type light fixture for illumination. The fixture comprises a body with a first flange having at least one hook-receiving opening and a second flange with a suspension-member-receiving opening. A cover includes a rectangular frame, at least one catch-arm and at least one suspension member. Frame fasteners along the frame engage the perimeter in a closed position. One-person attaching/closing and removal of the cover for maintenance is facilitated by the cover being supported in an open position, suspended position and fully engaged with the body in a closed position.

Abstract: A modular lighting fixture may include a housing having opposite ends, an endplate for fastening to one end of the housing, the endplate having a lens receiving face on a first side and an additional-structure-connecting face on a second side. The second side has an outer perimeter portion and a first peripheral surface, the first peripheral surface being inward of the outer perimeter portion. An additional structure is provided having a second peripheral surface with substantially similar contour as the first peripheral surface on the second side of the endplate. The additional structure is connected to the endplate with the second peripheral surface being proximate to the first peripheral surface of the second side of the endplate.

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.

Abstract: A modular, linear-type lighting fixture may include an elongate housing having lengthwise ends, and a pair of endplates adapted for sealing attachment to either lengthwise end of the housing, each of the endplates having respective perimeter surfaces adapted for attachment to any one of a bridge adapted for angularly-directable extension of the housing, a bridge adapted for linear extension of the housing, and an endcap. A modular lighting fixture may include first and second elongate housings each having ends, pairs of endplates for being respectively mated with the first and second ends of the first and second elongate housings, the endplates each having a rim, and a bridge adapted for joining one of the endplates of the first elongate housing with one of the endplates of the second elongate housing by sealing cooperation with the respective rims thereof. A lighting fixture may have one or more isolated raceways therein.

Abstract: A detention facility lighting fixture includes an elongate unibody housing having a flat back wall, four sidewalls including symmetrically sloped and opposed lengthwise sidewalls and trapezoidally shaped end sidewalls, at least one top wall, and welded seams at each of four corners, a door having a lens frame, a lens, and at least two Z-channels securing the lens to the lens frame, and a hinge secured to the housing, where the door and housing are adapted so that the top surface of the door, when closed, is essentially flush with the at least one top wall. A method includes providing a lighting fixture having a unibody housing with a flat back portion and beveled sidewalls, the housing being structured to receive a lens-holding door, and sealing a perimeter of the lighting fixture to the wall or ceiling with a continuous bead of security caulk.

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.

Abstract: A lighting fixture includes a lens frame having a rearmost rear-facing side with an outer perimeter, a baseplate connected to the lens frame, and a water shunt provided at the rearmost rear-facing side near the outer perimeter of the lens frame, the water shunt being structured for restricting water flow directed inwardly of the outer perimeter of the lens frame.

Abstract: There is described a multi-configurational, multi-functional electrical lighting fixture for high-abuse application and structured for surface mounting. The fixture includes a lens of U.V. stabilized, high impact-resistant, injection molded polycarbonate plastics, integrally formed with two selective, separate and distinct, high-performance reflector/refractor surface systems carried by the single lens, as separate zonal areas. The first system generates a long and narrow "throw", and the second system a short and wide "throw". A molded, opaque "eyelid" provides optimum lamp shielding and controls light distribution. The lens surmounts a lens base to which it is secured by means of unique internal, integrally-molded lugs received in cooperating hook-shaped slots. An 0-ring gasket establishes a water-tight seal. Unlocking of the assembly is deterred by means of a single, tamper-resistant screw. The lens base is mounted on a deep casting, with or without an interposed cast aluminum baseplate.

Abstract: A closure assembly to facilitate the sealing of each of a series of necked containers, each of different body configurations and contours, with the same hinged lid. The invention thus obviates the need for relatively complex and costly molds and effects substantial savings in manufacturing costs. The first component of the closure assembly is an adapter for mounting on a given particular container. The adapter includes a skirt for sleeved securement onto the neck of the container. A plate of the adapter overlies the container neck and is formed with a through port for discharge therethrough of material stored in the container. A second component of the closure assembly consists of a lid assembly, the same lid assembly being readily attachable to each of the different adapters, and, thus, to each of the different containers. The lid assembly includes a cover overlying the plate of the cap.
