Abstract
Embodiments of the invention provide for a lighting system for illuminating aisles with shelving. A rail can include a plurality of LEDs that extend along the length of the rail. The rail can be coupled with a node that includes various components along with an egress light source. The LEDs can be used to primarily illuminate the shelving on both or one side of the aisle. The egress light can be used to illuminate the aisle during times of emergency, at night, or when egress may be required.
Claims16
A light fixture comprising:
- a. a primary lighting subsystem adapted to emit light to illuminate an architectural space with a first illumination pattern, wherein the primary lighting subsystem comprises:
- at least one rail having a length and an end;
- a plurality of LEDs disposed along the length of the at least one rail;
- and
- an optical element disposed along the length of the at least one rail and positioned to distribute the light emitted from the primary lighting subsystem in the first illumination pattern, and
- b. a secondary lighting subsystem adapted to emit light to illuminate the architectural space with a second illumination pattern different from the first illumination pattern, wherein the secondary lighting subsystem comprises at least one node mechanically coupled with the end of the at least one rail,
- wherein the light fixture activates only one of the primary lighting subsystem and the secondary lighting subsystem at a time.
A light fixture for illuminating an architectural space having a vertical component and a horizontal component, the light fixture comprising:
- a. a primary lighting subsystem that emits light and comprises:
- i. a plurality of rails each having a length and an end;
- ii. a plurality of LEDs disposed along the length of each of the plurality of rails;
- and
- iii. at least one optical element disposed along the length of each of the plurality of rails, wherein the at least one optical element of each rail is adapted to direct a majority of the light emitted from the rail towards the vertical component of the architectural space;
- and
- b. a secondary lighting subsystem that emits light and comprises at least one node interposed between, and mechanically coupled to, the ends of adjacent rails, wherein a majority of the light emitted from the at least one node illuminates at least a portion of the horizontal component,
- wherein the light fixture is adapted to activate only one of the primary lighting subsystem and the secondary lighting subsystem at a time.
