Patent ID: 8339709

Claim:
A low numerical aperture system for transmitting light for interior lighting, comprising: a one-axis light tracking system for aligning a primary linear light concentrator towards a light source; a primary linear light concentrator for receiving light from the light source, concentrating and aligning the light, and directing the concentrated and aligned light towards a plurality of secondary concentrators; a plurality of linearly aligned secondary concentrators to receive the concentrated and aligned light from the primary linear light concentrator for additionally concentrating and for focusing the light to a diameter of a fiber optic bundle, and conducting the concentrated and focused light to a plurality of linearly aligned fiber optic bundles; a plurality of linearly aligned fiber optic bundles for conducting the additionally concentrated and focused light to a low-NA optimizer; and a low-NA optimizer configured to optimize the numerical aperture of the additionally concentrated and focused light within a thermodynamic limit and to transmit the low-NA optimized concentrated light for interior lighting.
