Abstract: An apparatus and method according to which a door is secured to a lighting device chassis.

Abstract: A recessed light fixture includes an LED module, which includes a single LED package that is configured to generate all light emitted by the recessed light fixture. For example, the LED package can include multiple LEDs mounted to a common substrate. The LED package can be coupled to a heat sink for dissipating heat from the LEDs. The heat sink can include a core member from which fins extend. Each fin can include one or more straight and/or curved portions. A reflector housing may be coupled to the heat sink and configured to receive a reflector. The reflector can have any geometry, such as a bell-shaped geometry including two radii of curvature that join together at an inflection point. An optic coupler can be coupled to the reflector housing and configured to cover electrical connections at the substrate and to guide light emitted by the LED package.

Abstract: A tool (20) for manipulation of a tubular fluorescent lamp (22) has a backplane (30), a coupler (32) for attachment to an external extension pole (36), a lamp gripper (38), a lamp extractor (44), and an extraction endpiece (50). The coupler (32) has a mechanism for angular adjustment (34). The lamp gripper (38) has a segmental cylindrical structure (40) with a non-slip inner surface (42) and an inner diameter generally coincident with that of the lamp (22). The lamp extractor (44) has an extraction extension (46) and an extraction stud (48) at the end of the extension (46). The Extraction endpiece (50) has an endcap (52) intended to fit over an end of the lamp (22) and an engagement fork (54) with which to engage the extraction stud (48).

Abstract: A tool (20) for manipulation of a compact fluorescent lamp (24) has a body (28) and a lamp holder (30). The body (28) has a coupler (32), for attachment to an extension pole (22), and a base (36), coupled to the coupler (32). The body (28) also has a detent (42) for attachment to the lamp holder (30). The lamp holder (30) is removably attached to the body (28). The lamp holder (30) has a baseplate (46) with a central opening (48) of a shape and size intended to admit a compact fluorescent lamp bulb assembly (44). The baseplate has a collar (50) with at least one protuberance (54) configured to engage the detents (42) on the body (28). The collar (50) has a plurality of grippers (52) axially extending therefrom.

Abstract: A modular luminaire consists of a rectangular housing having a top, first and second sides and first and second ends, with an open light-emitting bottom. Elongated reflector members are located in a side-by-side relationship in the housing for independently reflecting the light from a compact fluorescent lamp from each of the reflector members out of the open bottom of the housing. The reflector members may be made as a single unit or as separate, independent individual units. The edges of the separate, individual reflector members are made to releaseably interconnect with one another; so that any desired number of reflector members and corresponding compact fluorescent lamps may be mounted in a side-by-side relationship in housings of different widths to provide the desired amount of light. Fixtures are designed to replace HID lamps and conventional, low efficiency fluorescent lamp luminaires.

Abstract: A lighting system employs luminaires having reflectors with a fluorescent lamp support frame at the base end of the inside of the reflector. The support frame includes a plurality of extensions for holding the bases of compact fluorescent lamps arranged in a general star configuration around the center line of the reflector. The extensions are at an angle to cause the compact fluorescent lamps to follow the outwardly-flared inside surface of the reflector. A system of luminaires then provides a substantially uniform volume of light in a facility due to the patterns of overlapping light contributed by the individual luminaires.
