Abstract
The inventive system, which is used in transmitting illumination from a central source to a variety of remote locations, efficiently couples the light originating from a lamp, or similar source, into a multiplicity of flexible macroscopic light guides. The combination of the several elements of the inventive system results in a very efficient transfer of the energy of the light source to the light guides. Light from the lamp is fed to four or more ports, with each port having one or more flexible macroscopic light guides connected thereto.
Claims16
A light guide illumination system, comprising:
- a light source for emitting light;
- at least three curved reflectors disposed in proximity to the light source;
- at least one multi-sectored lens;
- and
- at least one output light guide, the at least one multi-sectored lens being adapted for receiving reflected light from said light source and for focussing the light into the at least one output light guide.
A light guide illumination system, comprising:
- a light source for emitting light;
- at least three mixing rods;
- at least three curved reflectors disposed in proximity to the light source, the at least three curved reflectors being adapted for reflecting the emitted light from the light source into the at least three mixing rods;
- a multi-sectored lens;
- and
- at least one output light guide, the multi-sectored lens being adapted for receiving the reflected light from one of the at least three mixing rods and for focussing the light into the at least one output light guide.
A light guide illumination system, comprising:
- a light source adapted for emitting light;
- a multi-reflector comprising at least three curved surfaces, the multi-reflector being disposed in proximity to the light source and being adapted for reflecting the light emitted from the light source;
- and
- a multi-sectored lens, the multi-sectored lens being adapted for receiving the reflected light from the multi-reflector and for focussing the light into at least one output light guide.
A light guide illumination system, comprising:
- a light source for emitting light;
- four mixing rods;
- four curved reflectors disposed in proximity to the light source, the four curved reflectors being adapted for reflecting the emitted light from the light source into the four mixing rods;
- at least one multi-sectored lens;
- and
- at least one output light guide, the at least one multi-sectored lens being adapted for receiving the reflected light from one of the mixing rods and for focussing the light into the at least one output light guide.
