Abstract: Lighting fixtures using light-emitting devices are disclosed with heat sinks that are both decorative and functional by providing heat dissipation for the light-emitting devices used therein. A luminaire can feature a base for attachment to a support and a driver positionable in the base. An electrical connector can extend downward from the base and have a proximal end and a distal end with the proximal end disposed in the base and engaging the driver. A heat sink can be disposed at the distal end of the electrical connector with the electrical connector extending through the heat sink. A light-emitting device can be attached to the heat sink and connect with the electrical connector such that the driver is electrically connected to the light-emitting device. A lamp shade can be secured to the heat sink proximal to the base with the light-emitting device disposed within the lamp shade and at least a portion of the body of the heat sink forming a decorative portion extending outward from the lamp shade.

Abstract: A light emitting device assembly can include a plurality of substrates, extending in a longitudinal direction, that are coupled together to provide a plurality of surfaces that face in respective radial directions that are orthogonal to the longitudinal direction. A heat sink can be coupled to the plurality of substrates, and the heat sink can extend radially from the plurality of substrates and is configured to transfer heat away from the plurality of substrates.

Abstract: The disclosure describes devices that are used in conjunction with a pair of (single wattage) compact fluorescent lamps (CFL). In some embodiments, the devices can emulate the behavior of a 3-way incandescent bulb used in a standard 3-way lamp socket. Such can allows people to retain the benefits of their existing Edison-base (E26d) 3-way lamps with the improved energy efficiency and color temperature of modern CFL technology in a cost effective and flexible way. Light fixture conversion kits for allowing an incandescent lamp to accept CFL bulbs are also described.
