Claims
- 1. A device for the collection and transmission of electromagnetic radiation comprising:
- a cylindrical fluorescent fiber formed from a light transparent fiber material on which has been applied at least one fluorescent sheet, said fluorescent sheet being formed from a fluorescent dye incorporated in a polymeric binder;
- reflector means for reflecting radiation impinging over a relatively wide area so as to impinge on the circumference of said fluorescent fiber;
- at least one optical wave guide optically coupled to one end of said fluorescent fiber whereby light impinging on said fluorescent fiber is internally reflected and transmitted by said optical wave guide to a point of use.
- 2. The device of claim 1 wherein said reflector means is a parabolic reflector.
- 3. The device of claim 1 wherein said reflector means is a compound parabolic reflector.
- 4. The device of claim 2 or 3 wherein at least one optical wave guide is optically coupled at one end to each end of the fluorescent fiber.
- 5. A solar energy collection and transmission device comprising:
- a cylindrical fluorescent fiber formed from a light transparent fiber material on which has been applied at least one fluorescent sheet, said fluorescent sheet being formed from a fluorescent dye incorporated in a polymeric binder;
- a compound parabolic reflector for focusing solar radiation incident on the circumference of said reflector onto said fluorescent fiber;
- at least one optical wave guide optically coupled to said fluorescent fiber whereby solar radiation impinging on said fluorescent fiber is internally reflected and directed toward said optical wave guide for transmission therethrough to a point of use.
- 6. The device of claim 5 wherein the compound reflector has a cusp and said fluorescent fiber is positioned adjacent said cusp.
- 7. The device of claim 6 wherein said device has an angle of acceptance of about 60.degree..
