Abstract: A lighting fixture includes a fixture housing. A circuit board is positioned in the fixture housing. The circuit board includes a driver circuit. A plurality of light emitters are disposed on the circuit board. The light emitters are operatively connected to the driver circuit to produce a light output. A temperature sensor is disposed on the circuit board, the temperature sensor configured to measure a temperature of the circuit board and output a signal. The driver circuit is configured to reduce the light output in response to the signal from the temperature sensor.

Abstract: A ceiling fan is provided. The ceiling fan includes one or more fan blades. The ceiling fan further includes a motor. The motor is operatively coupled to the one or more fan blades. The motor is configured to drive rotation of the one or more fan blades. The ceiling fan further includes a light kit. The light kit includes a panel. The panel has an edge extending between a top surface of the panel and a bottom surface of the panel. The light kit further includes at least one light source positioned to illuminate the edge.

Abstract: A light fixture includes a housing for supporting a light source and an enclosure for supporting a driver in electrical communication with the light source. The enclosure is selectively supported in one of a first position and a second position while maintaining electrical communication between the driver and the light source in both positions. The enclosure is directly coupled to the housing in the first position, and the enclosure is supported separately from the housing in the second position.

Abstract: A switch includes a first terminal, a second terminal, and a third terminal. The switch includes an output node coupled to the second terminal and the third terminal. The switch includes a contactor coupled to the first terminal and movable between at least a first position and a second position. The first terminal is coupled to the second terminal when the contactor is in the first position. The first terminal is coupled to the third terminal when the contactor is in the second position. When the contactor is in the first position, the switch is configured to provide direct current power at the output node. When the contactor is in the second position, the switch is configured to provide alternating current power at the output node.

Abstract: A method and apparatus for determining the circadian input of a light source includes selecting a circadian input to be measured based on an action spectrum corresponding to a wavelength sensitivity of photoreceptors for a circadian regulation system, where the circadian input is configured to stimulate a retinaldehyde photopigment, and for measuring spectral intensity across the action spectrum to determine the circadian input of the light source.

Abstract: The present invention involves a light system for stimulating or regulating neuroendocrine, circadian, and photoneural systems in mammals based upon the discovery of peak sensitivity ranging from 425-505 nm; a light meter system for quantifying light which stimulates or regulates mammalian circadian, photoneural, and neuroendocrine systems. The present invention also relates to translucent and transparent materials, and lamps or other light sources with or without filters capable of stimulating or regulating neuroendocrine, circadian, and photoneural systems in mammals. Additionally, the present invention involves treatment of mammals with a wide variety of disorders or deficits, including light responsive disorders, eating disorders, menstrual cycle disorders, non-specific alerting and performance deficits, hormone-sensitive cancers, and cardiovascular disorders.

Abstract: An outdoor lighting fixture that is capable of being mounted flush with a mounting surface is provided. In one embodiment, the outdoor lighting fixture contains a housing having an upper and lower portion. A light source is in operable communication with the housing and can provide light in a direction that is substantially parallel to the mounting surface. It has been discovered that the outdoor lighting fixture of the present invention can be mounted substantially flush with a mounting surface so that it remains relatively hidden from view during use. Furthermore, the outdoor lighting fixture can also provide light in a linear direction, thereby enabling it to illuminate paths, sidewalks, driveways and the like, without having to provide light in all directions.

Abstract: A light assembly with a removable reflector for use in a ceiling, wall, or the like is provided. The reflector has a top surface with a substantially hurricane-shaped mounting aperture defined by a primary diameter and a secondary diameter that intersect each other and in which the primary diameter is greater than the secondary diameter. When the reflector is rotated, the secondary diameter approaches a holding key in the light assembly, which engages the top surface to releasably hold the reflector within the light assembly. A method of releasably installing the reflector is also described.

Abstract: A recessed lighting fixture that includes a battery assembly integrally connected to a recessed enclosure is provided. The battery assembly includes a battery that can supply the lighting fixture with power in the event of a power outage. In one embodiment, the battery assembly includes a ballast plate to which the light source (e.g., incandescent or fluorescent lamps) and the battery are connected. The ballast plate can be connected to the recessed enclosure so that the battery is disposed within an open face defined by the recessed wall enclosure. As a result, the lighting fixture can be formed as an integral structure that can be easily installed and accessed by a user.

Abstract: A fire assembly that can be used for installing recessed electrical fixtures into various structures such as wall assemblies is provided. The fire assembly includes an electrical fixture contained within a generally fire-resistant housing. The housing can enclose the electrical fixture in such a manner that the resulting fire assembly has an integral structure. In some instances, a support structure can be utilized to attach the housing to the electrical fixture. Furthermore, the housing can be a cube-shaped box have a variety of generally fire-resistant walls. These walls can be made from materials such as sheet rock.
