Abstract: A lighting component may include a light emitting diode (LED) positioned on a printed circuit board assembly (PCBA), and a reflector positioned on the PCBA over the LED. The LED may be configured to emit an effective span of light which may pass through the reflector from a rearward opening to a forward opening of the reflector. The reflector may include a first region with one or more surfaces configured to subtend a first portion of the effective span of light. The reflector may include a second region with one or more first surfaces configured to subtend a second portion of the effective span and one or more second surfaces configured to subtend exterior light entering the forward opening back through the forward opening. The reflector may include a third region with one or more surfaces configured to subtend exterior light entering the forward opening back through the forward opening.
Abstract: A light fixture is provided that includes lighting components having one or more surfaces that subtend light emitted by one or more light sources into one or more corresponding subtended spans. Additional light sources are provided within the light fixture to exhibit back lighting effects that may be seen at various locations external to the light fixture and that may highlight other features of the light fixture intended as aesthetic features. Both the forward projected ray sets and the aesthetic lighting may be controlled independently of each other.
Abstract: An optic configuration including a PCBA with one or more LEDs mounted thereon to emit light through a lens and a reflector. The optic configuration may be assembled within a cavity of a lighting fixture. At least a portion of the emitted light may be subtended by the lens, such that the lens may subtend light through a number of regions (e.g., three distinct regions). At least a portion of the emitted light may be subtended by the reflector, such that the reflector may subtend light from a number of surfaces (e.g., four surfaces). At least a portion of the light subtended by the lens may further be subtended by the reflector. The light subtended by the lens and/or the reflector may form a beam pattern including a high intensity spot portion and a lower intensity flood portion.
Abstract: A method and apparatus for collecting and projecting light into a specified target illuminance. A lens may be mounted or otherwise paired to a carrier to form a lens/carrier combination, which may then be mounted to a printed circuit board assembly (PCBA) containing a light emitting diode (LED). The lens/carrier combination may establish an optimum optical relationship between the LED and the lens, such that a predetermined photometric distribution of the LED is collected by the lens, while the remaining photometric distribution of the LED is rejected by the carrier. The lens may include a first pair of opposing surfaces forming a first focus and a second pair of opposing surfaces forming a second focus. The first and second foci may cause light to be subtended into one or more of collimated light focused light, diffused light, and shifted light. The carrier may include an obstruction extending toward the PCBA.

Abstract: A method and apparatus for a curved lighting fixture that is symmetric about a longitudinal axis of the curved lighting fixture. The curved lighting fixture includes end caps that are parallel to the longitudinal axis. Each end cap includes two mounting studs that secure the lighting fixture to mounting brackets, where a first mounting stud provides an axis of rotation for the lighting fixture and a second mounting stud facilitates the rotation. The two mounting studs do not enter into an interior portion of the lighting fixture so as to facilitate externally serviceable hardware. A bushing provides an external retention mechanism to retain the two mounting studs within each end cap.
Abstract: A rail nut spacer is shown and described, and may have a body and one or more threaded inserts positioned along a width of the body. Threaded inserts may be retained within the rail nut spacer by surface characteristics on each insert to prevent movement thereof with respect to the rail nut spacer. The rail nut spacer may be inserted in a first direction into a slot extending through a width of a housing, such that the slot prevents movement of the rail nut spacer in a second direction. Fasteners may extend through a bezel, through the slot, and/or through the threaded inserts to secure the bezel to the rail nut spacer. The bezel may exert a force on a media to secure the media to the housing. The bezel, media, and/or housing may be sealed together by a gasket to protect an interior of the housing from contaminants.
Abstract: A lighting system may include a reflector having at least one surface forming an interior. The reflector may have a forward opening and a rearward opening. The lighting system may further include an LED positioned at the rearward opening to direct light through the interior of the reflector. The lighting system may further include a lens positioned within the reflector, wherein the lens is formed of a segment of a toroid.
