Abstract: An integrated cardan mechanism for an adjustable luminaire for a lighting system. In an embodiment, a ring component includes a generally circular ring, a first inward connector having a through hole and extending inwardly from the ring component along a first axis, a second inward connector portion having a through hole and extending inwardly from the circular ring component along the first axis opposite the first inward connector, a first outward connector comprising a through hole and a first tab and extending outwardly from the ring component along a second axis, and a second outward connector comprising a second through hole and a second tab and extending outwardly from the circular ring component along the second axis opposite the first outward connector.

Abstract: A tilting mechanism for a luminaire assembly is provided. The tilting mechanism includes a first rotating connection between a first housing of the luminaire assembly and an exterior surface. The first housing configured to pivot relative to the exterior surface around a first axis defined by the first rotating connection. The tilting mechanism also includes a second rotating connection between the first housing and a second housing of the luminaire assembly. The second housing is configured to pivot relative to the first housing around a second axis defined by the second rotation connection. The first axis defined by the first rotating connection between the first housing and the exterior surface and the second axis defined by the second rotating connection between the first and second housing are transversely oriented with each other.

Abstract: A luminaire housing assembly includes an outer side wall extending between a lower end and an opposite upper end. The side wall is shaped to extend around a perimeter of one or more light generating devices of a luminaire. The housing assembly also includes a base plate coupled with the upper end of the side wall. The base plate includes vent openings for convection of heat generated by the one or more light generating devices out of a volume encircled by the side wall, wherein the side wall is joined to the base plate by a press fit connection.

Abstract: According to some embodiments, a light cover includes a first end having an opening adapted to receive an illuminating bulb portion of a compact fluorescent lamp. The light cover may further include an outer surface contoured substantially in the shape of an illuminating bulb portion of an incandescent light bulb, wherein the outer surface is configured such that one or more open portions are provided.

Abstract: According to some embodiments, a light cover has an axis extending vertically from a threaded base portion to an end portion opposite the threaded base portion. The light cover may include a vertically open, pear-shaped first half portion (e.g., formed of plastic). The light cover may further include a vertically open, pear-shaped second half portion coupled to the first half portion to form a cavity to hold an illuminating bulb portion of a compact fluorescent lamp. The first and second half portions together may form an outer surface contoured substantially in the shape of an incandescent light bulb.

Abstract: A compact fluorescent lamp (CFL) ballast driver includes first, second and neutral AC voltage terminals, a full wave rectifier between the first AC voltage terminal and the neutral AC input terminal, and a separate branch between the second AC voltage terminal and the neutral AC input terminal. A resonator circuit includes at least two inductors and provides its output voltage to a CFL lamp. The driver includes a first state detector circuit to monitor the first AC voltage terminal, and a second state detector circuit to monitor the second AC voltage terminal. The first and second state detector circuits activate respective first and second switches. The first switch shunts one inductor of the resonator circuit, and the second switch shunts another inductor of the resonator circuit. The driver can be housed in a CFL having a capper, a three-way lamp base adjacent to the capper and an arc tube.

Abstract: A lamp includes a collar with internal and outer surfaces, where two or more connection pins extend from the internal surface of the collar. At least two connection pins have a head portion distal from the collar internal surface. The head portions include a slot. The lamp includes a light source with at least two external lead-in wires. The lead-in wires are located within respective slots and are mechanically coupled to respective surfaces of the slots in a press-fit manner which may be free of wrapping, winding, twisting, or soldering. A PCB disposed inside the lamp has two opposing surfaces and a rim between the two opposing surfaces. There are conductive surfaces disposed on at least one of the rim and one of the opposing surfaces at positions corresponding to connection pin slots. The PCB is located between connection pins with the conductive surfaces in electrical communication with the lead-in wires.
