Abstract: A lighting unit includes an architectural panel having an overall thickness that is measured between a first surface that is configured to be exposed to light output by the lighting unit and a second surface that is opposite the first surface, and a light fixture embedded in the architectural panel. The light fixture includes a solid state light source, an optic, a power supply and a driver circuit that at least partially embedded in the recess of the panel. The light fixture is configured to output light in an output direction extending out away from the first surface of the panel. The light fixture extends from the first surface of the panel in a direction opposite the output direction by a distance that is less than the overall thickness of the architectural panel.

Abstract: Described are integrated lighting systems incorporating ambient lighting, task lighting, and/or emergency lighting into a single, aesthetically pleasing lighting system. Main line power is directed to an ambient lighting fixture, and then may be transferred to one or more additional ambient lighting fixtures. The ambient lighting fixtures may include a power supply and receptacle to transfer excess power to a task or emergency lighting fixture through a low-power cord. The cord and receptacle allow the task or emergency lighting fixture to be easily connected or disconnected from the ambient lighting fixtures without the need for a trained electrician. A similar power delivery system may also be used to easily connect or disconnect emergency lighting fixtures from a dedicated emergency power source. The resulting lighting system allows for easy adjustment or tailoring of the lighting conditions to the changing needs of a space without requiring special training or personnel.

Abstract: Light fixtures having a plurality of light-emitting diodes that maximize the amount of direct light into an intended area. The light fixture may include a carriage with a first (top) end and a second (bottom) end. A hood may be mounted to the first end of the carriage. At least one light engine comprising a plurality of light sources is mounted to the hood. The light sources emit light downwardly directly onto an intended area. In certain embodiments the second end of the carriage is shaped and sized so that it does not interfere with emission of the light to the intended area. The light fixture thus provides light in a thermally efficient manner, maximizes the amount of direct light, and limits the amount of light pollution.

Abstract: Light fixtures including a housing that acts as a heat sink, and additionally includes structure to selectively position the light fixture at different orientations. In certain embodiments, the light fixture includes a housing, a light source, and a bracket. Set of fins may protrude from the housing, and flanges may protrude from the bracket. In use, the flanges engage ribs on the housing to support the lighting fixture. By altering the engagement between the flanges and ribs, the light fixture may be re-positioned within the bracket in a number of different orientations, creating a number of light distribution options for the light fixture.

Abstract: Light fixtures comprising an organic light emitting diode (OLED) as the light source, and further comprising a housing, at least one hollow, and an optic. The at least one hollow defines an intended area where light is emitted, and includes a reflective surface to reflect light within the intended area. The optic comprises a refractive portion that is defined by two edges. In one embodiment, the OLED is coupled to the two edges of the optic. In another embodiment, the OLED is coupled to and contacts an inner surface of the refractive portion. In either embodiment, the OLED is either sufficiently close to or contacting the refractive portion such that surface area of emitted light is maximized. Additionally, the OLED is placed sufficiently close to (or within) the intended area that reflected light and optical efficiency are maximized.

Abstract: A dispenser for dispensing sheet material from a roll has a storage section wherein at least one reserve roll can be stored on a storage mandrel until depletion of a supply roll positioned on a dispensing mandrel in a dispensing section. Upon depletion of the supply roll, the user may pivot and remove the roll core from the dispensing mandrel. Upon return of the dispensing mandrel to its dispensing position, under a spring bias, the dispensing mandrel displaces and thereby releases a spring arm holding the reserve roll in the storage position against the bias of a spring urging the reserve roll toward the dispensing section. Upon release, the spring pushes the reserve roll onto the dispensing mandrel for dispensing.
