This Cassegrain parabolic dish concentrator energizes eight 1/2" diameter fiber-optic strands to 11000 lumens each. The fiber is then routed through the ceiling (roof) of the building and terminates on the Bio-Reactor plates shown below.
This prototype was designed at Oak Ridge National Laboratories in Tennessee and is installed on the roof of a lab at Ohio University for a joint test of the fiber-optic lighting and the reactor.
The ultimate use for the system will be for room daylighting where the fiber is combined with special florescent lights that can operate on a computerized dimmer.
