Abstract:
1. A tracking system configured to orient light concentrators to face a light source, the system comprising: a support structure for providing global alignment of the light concentrators with the light source; a plurality of light concentrator (LC) modules coupled to the support structure and having respective arrays of the light concentrators that are in fixed positions with respect to other light concentrators in the respective array, the support structure configured to rotate the plurality of LC modules about a first global axis and rotate the plurality of LC modules about a different second global axis to globally align the plurality of LC modules with the light source, wherein the first and second global axes are non-parallel; and secondary alignment mechanisms that are each coupled to the support structure and a respective LC modules, each of the secondary alignment mechanisms comprising a module joint that movably couples the respective LC module to the support structure and an actuator assembly, wherein the actuator assembly is configured to selectively move the respective LC module about first and second joint axes relative to a pivot point of the corresponding module joint thereby orienting the respective array of light concentrators of the respective LC module, wherein the secondary alignment mechanisms and the LC modules that are coupled to the secondary alignment mechanisms move as a group when the support structure rotates to globally align the light concentrators; wherein the secondary alignment mechanisms are capable of selectively moving the LC modules independently with respect to one another such that different respective LC modules may be moved by different amounts.
