Abstract: A device for holding and positioning an optic, such as a refractive lens, over a light source such as a light emitting diode. The refractive lens is frustum-shaped with an upper light-exiting end having an upper rim, a lower light-entering end, and a conical sidewall that tapers from the upper rim to the lower end. The device has a channel including a base and first and second sidewalls extending from the opposed side edges of the base, and further having one or more optic holding positions. The optic holding position includes an aperture formed in the base that is configured to receive the conical sidewall of the optic, and an aperture formed in a portion of each sidewall, adjacent the aperture in the base, for retaining a portion of the upper rim of the optic lens. The aperture can include a slot opening through which a portion of the upper rim of the optic lens at least partially extends.

Abstract: A luminaire for lighting a traffic surface in a tunnel is disclosed, wherein the luminaire has light sources disposed in an array for casting light on a traffic surface and structure for controlling and directing the light, such as a reflector or refractor lens. The luminaires are positioned along the length of the tunnel at angles to the traffic surface facilitating optimal use of the generated light. The luminaire is configured as a module that can be quickly installed into a support track mounted on the tunnel walls, and is dust and waterproof to endure mechanical and high pressure water cleaning by conventional tunnel washers. The luminaire is particularly well suited to employ light emitting diodes for generating and casting light.

Abstract: Lighting assemblies with light sources are disclosed for use in place of fluorescent lights. A support member can be attached to brackets, which can snap into a spring lampholder brackets used for a fluorescent light. For holding a support member, an offset bracket can be used or alternatively, a bracket with a tab or set screw can be used. The disclosed lighting assemblies are particularly well suited for providing light from light emitting diodes. Methods for manufacturing light strip assemblies are also disclosed. Each support member can be positioned on a supporting surface so that a support surface of the light strip is substantially horizontal. A lens can be formed on each light source. Application to refrigerated cases is described.

Abstract: A linear light system, and a linear luminaire used in the system, for lighting a traffic surface. The linear luminaire has a plurality of light emitting diodes (LEDs) disposed in a linear matrix along the length of the traffic surface, and a plurality of refractive lenses for directing the emitted light from the LEDs at the traffic surface. The traffic surface is typically the roadway of a tunnel. A refractor lens is used to direct the emitted light from the LEDs predominantly toward at least the traffic surface.

Abstract: A foldable element support made from planar sheet of material that can be formed by folding into a support for positioning and securing a refractor lens to a luminaire housing. The foldable element support is a planar sheet that has a central base having a central opening, a plurality of foldable securing arms formed into the central base for attaching the support to a luminaire housing, and a plurality of peripherally-arranged support flanges for supporting and positioning the upper rim of the refractor lens in proximity to the luminaire housing. The folded support can be manipulated into the folded configuration by hand, with hand tools, or by a machine.

Abstract: A lampsocket having a porcelain body that has a base, a peripheral wall, and at least two of a rigid, longitudinal spacer projecting axially outwardly from the base. The longitudinal upper surfaces of the spacers engage opposite areas of the bottom of the base of the lamp. The lampsocket is intended for use with and to operate a class of lamps having a threaded base having an insulated extension from the central portion of the bottom of the lamp base, and a central button mounted on the insulated extension. The lampsocket can also accept, but can not make electrical contact with, other lamps that have a conventional base contact without the insulated extension.

Abstract: A luminaire reflector formed from at least one sheet of reflective material is folded and curved by hand to form a self-standing reflector having a predetermined three-dimensional reflector shape. Each sheet of reflective material includes integral panels that are joined to adjacent panels through fold lines that allow the panels to be folded by hand. The panels have free edges that are folded and/or curved into abutting relationship. The panels include locking members and positioning tabs formed adjacent the free edges to retain the reflector in a predetermined three-dimensional reflector shape. Methods of making a self-standing reflector for a luminaire are also disclosed.

Abstract: A retrofit luminaire assembly for mounting in an existing canopy fixture housing and methods of installing same. The retrofit luminaire assembly includes a planar panel having electrical control elements mounted to an upper surface of the panel. A lamp is received in a lamp socket mounted to the panel with a light-emitting section of the lamp extending away from a lower surface of the panel. A lens is mounted to the lower surface of the panel for enclosing the light-emitting section of the lamp. The panel preferably has a pair of oppositely directed pivot members which are adapted to engage with inwardly directed flanges of the canopy fixture housing to removably and pivotally support the panel for movement between a vertical, inoperative position and a horizontal, operative position. Flange extension members are provided to engage the inwardly directed flanges of the fixture housing to reduce the size of the opening for larger fixture housings to a desired common size opening.
