摘要:
The system captures and concentrates sunlight for transmission to interior spaces or to a PV system. A solar collector uses arrayed refractive lenses (20) and opposing concave focusing mirrors (22) and a movable coupling sheet (30) forming part of a lightguide (26). The transparent sheet (30) contains small angled mirrors (32), where each angled mirror (32) corresponds to a particular set of the lenses/focusing mirrors and is in the focal plane. The lightguide (26) also includes a fluid (28) surrounding the transparent sheet (30), and lower index cladding layers (29) sandwich the fluid. The sheet (30) is translated within the fluid (28) by an actuator to position the angled mirrors (32) at the focal points of the sunlight for maximum deflection of the sunlight to an edge of the lightguide (26) for extraction to a light transmission system or to a PV system. A position sensor on the sheet (30) provides feedback regarding the position of the angled mirrors (32) relative to the focal points.
