Abstract:
1. A low numerical aperture system for transmitting light for interior lighting, comprising: a light tracking system for aligning at least one light concentrator towards a light source; at least one light concentrator for receiving light from the light source, concentrating the light and directing the concentrated light towards at least one highly reflective mirror; at least one highly reflective mirror movably affixed to a low-NA optimizer and configured to coordinate to a solar tracking axis by the light tracking system to reflect the concentrated light into the low-NA optimizer; and a low-NA optimizer comprising at least one light guide having at least one optical axis and at least one light guide mirror such that the low-NA optimizer is configured to orient the concentrated light along the optical axis and to optimize the numerical aperture of the concentrated light within a thermodynamic limit and to transmit the low-NA optimized concentrated light for interior lighting.
