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 high efficiency heat-dissipating dome lamp utilizes convex centralized optics and tiered venting to house concurrently inwardly canted compact fluorescent lights, ballast for the lights, and an emergency ballast system.

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.
