Abstract: A multi-wing edge-lit structure includes a first edge-lit light guide panel, a second edge-lit light guide panel, and a joiner unit. The first edge-lit light guide panel is adjustably attached to the joiner unit on a first side of the joiner unit. The second edge-lit light guide panel is adjustably attached to the joiner unit on a second side of the joiner unit. The first side and the second side are opposite sides of the joiner unit.

Abstract: A linear light emitting diode (“LED”) light fixture includes LED modules that interface with one another to provide a substantially continuous array of LED's. This continuous array allows for substantially uniform light output from the LED light fixture. The LED modules can interface with one another via one or more connectors, which allow two or more LED modules to be electrically and mechanically coupled together. The connectors may be disposed beneath the LED's so that the connectors are not visible when the LED modules are coupled together. The connectors may be disposed along opposite ends of the modules to allow for end-to-end configurations of the modules and/or along side ends of the modules to allow for angled or curved configurations of the modules. The LED modules can be powered via one or more wires, magnets, or clips, which are coupled to a power source.

Abstract: A direct-indirect luminaire including a pair of sockets for receiving at least one tubular fluorescent lamp; a louver, arranged on one side of the lamp socket, for controlling downlight from the lamp; and a shutter, arranged on an opposite side of the lamp socket, for controlling uplight from the lamp. The shutter may include a plurality of adjustably sizeable apertures which may be formed by adjacent members that are slidable relative to each other, with matching patterns of overlapping openings. The adjacent members may further include nested concave surfaces facing the lamp, such as channel-shaped members with openings that are arranged on at least two walls of the channel. A positioner may also be provided for designating a size of the apertures. For example, the positioner may include a protuberance on one of the adjacent members for engaging a hole in the other of the adjacent members.
