This study presents a trough daylight concentration and axial transmission system (TDCAT) based on the previously studied mirror image co-focus concentrator. The TDCAT system concentrates sunlight into a light guide tube where the concentrated sunlight undergoes multi-reflection to be transmitted or eventually absorbed by the media in the tube. Therefore, a TDCAT system would be suitable for tubular solar bio-reactor or photocatalysis applications. The optical simulation is employed to analyze the effect of the design parameter on the system performance. Construction and testing of a prototype TDCAT system is also described and discussed.
