Abstract: An improved system for synchronizing the positioning of a reflector assembly used in solar lighting apparatus for illuminating the interior of a roofed building. The reflector assembly is rotatable about a vertical access for tracking daily movements of the sun. The assembly includes return, track and seek sensors, the return sensor, in the turn-on mode, generating a signal corresponding to sensed sunlight, which energizes the systems motor. The system comprises the master tracking assembly and a plurality of follower units. Each motor shaft extends into a gear box and is coupled to a worm gear. A radial worm gear is mounted to a shaft member and is driven by the worm gear. The shaft member in turn drives the mirror reflector assembly. A stepper wheel having a plurality of indentations formed thereon is also mounted to the shaft member.
