Abstract
Embodiments disclosed herein generally relate to lighting an interior of an enclosure using light emitting diodes (LEDs). In one example, a lighting system is provided. The lighting system includes one or more selective light directors having one or more point sources of light disposed along a length of the selective light director, a circuit board coupled to at least one end thereof, and a light emitting diode directing light into the selective light director.
Claims22
A lighting system for an aircraft, comprising:
- one or more selective light directors coupled to a fuselage of the aircraft, each of the one or more selective light directors having one or more point sources of light disposed along a length of the selective light director, a circuit board coupled to at least one end thereof, and a light emitting diode directing light into the selective light director, wherein the light emitting diode is adapted to receive alternating current power from an alternating current power source located on the aircraft, and wherein each of the one or more selective light directors include a core surrounded by a cladding, and a reflector region at least partially covering an outer circumferential surface of the cladding.
A lighting system for an aircraft, comprising:
- one or more selective light director assemblies positioned in a fuselage of the aircraft, each of the selective light director assemblies comprising:
- a selective light director coupled to a circuit board, the selective light director including a core at least partially surrounded by a cladding with a reflective layer at least partially covering a circumferential outer surface area of the cladding and having one or more point sources of light formed along a length of the selective light director;
- and
- a light emitting diode coupled to the circuit board and directing light into the selective light director on at least one end thereof.
1 more element
A lighting system for an aircraft, comprising:
- a plurality of selective light director assemblies disposed along a length of a cabin, the plurality of selective light director assemblies comprising two side wall selective light directors, a ceiling selective light director and four cross-bin selective light directors, each of the selective light directors being coupled to a circuit board and a light emitting diode which is adapted to receive alternating current power from an onboard alternating current power source, each of the light emitting diodes directing light into the selective light director, wherein at least a portion of the side wall selective light directors comprise a core surrounded by a cladding, and a reflector region at least partially covering an outer circumferential surface of the cladding and the ceiling selective light director and the cross-bin selective light directors comprise one or more point sources of light.
