A sunlight redirector has a first mirror array formed of a first plurality of substantially parallel, uniformly spaced, longitudinal outward mirror segments; and a second mirror array formed of a second plurality of substantially parallel, uniformly spaced, longitudinal inward mirror segments. Each mirror segment has a normal vector. The outward mirror segments are adjustably positionable, such that their normal vectors remain parallel. The first mirror array is rotatable about a normal vector of the sunlight redirector. The inward mirror segments may remain fixed in position at all times; or they may be moved, twice per day, between first and second fixed positions.

Sunlight redirector with fixed mirror segments

A light concentrating apparatus is presented. Disclosed apparatuses include a collection of shaped reflectors capable of redirecting incident light, sunlight for example. The reflectors are configured to modify the spatial distribution of the redirected light in a manner where the distribution of light associated with a first dimension is modified differently than the distribution of light associated with a second, different dimension, via a relay of reflections. Contemplated apparatuses generate a substantially collimated output beam subsequent to the relay of reflections.

Light concentrating apparatus

A light collecting and disseminating apparatus is provided for use in harvesting sunlight from the exterior of a man-made structure, and providing light to the inside of the structure, via an opto-mechanical joint where sunlight would not normally be available. The internal arrangement of the collector allows for improved optical accuracy and performance over prior efforts. The apparatus is also characterized as possessing a low profile so as not to alter the appearance of buildings furnished with the invention. Further, light can be collected from any orientation and redirected through the opto-mechanical joint to a stationary light receiving port independent of the orientation of the collectors.
