Abstract
The present invention provides a system for the collection of electromagnetic radiation and the transmission of that radiation to a point of use. In its simplest sense, an apparatus for the collection and transmission of electromagnetic radiation comprises a cylindrical fluorescent fiber, at least one end of which is optically coupled to an optical wave guide, and means for reflecting solar radiation impinging over a relatively wide area onto said cylindrical fluorescent fiber. Preferably, a compound parabolic mirror is employed for reflecting incident solar radiation onto the optical fluorescent fiber.
Claims7
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.
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.
