Abstract:
A non-imaging solar concentrator comprising:a primary concentrator for concentrating ambient light into a primary beam; a turntable having a central aperture and a rotatable portion, the rotatable portion being rotatable about a turntable axis, the central aperture being sized to permit the primary beam to be transmitted therethrough; a first support structure coupling the primary concentrator to a first side of the rotatable portion of the turntable; a second support structure coupled to a second side of the rotatable portion of the turntable opposite the first side; a secondary concentrator coupled to the second support structure, the secondary concentrator having a frusto-conical reflective surface and a beam aperture, the beam aperture being sized to permit a focused portion of the primary beam to be transmitted therethrough, the frusto-conical reflective surface being configured to reflect an unfocused portion of the primary beam back to the primary concentrator; and a drive mechanism coupled to the rotatable portion of the turntable and operable for rotating the rotatable portion of the turntable about the turntable axis.
