ABSTRACT:
A self contained solar beacon for reflecting sunlight over a large number of widely scattered reflection paths. The beacon includes three reflector arrays secured to the outer ends of respective horizontal reflector shafts which extend radially from a central mounting plate. The mounting plate is rotated about a vertical axis by an electric motor which is connected to the mounting plate through a drive shaft. The reflector shafts are rotatably carried by the mounting plate, and their inside ends terminate in respective friction discs which roll along a stationary friction plate. Consequently, as the motor rotates the mounting plate, the reflector arrays simultaneously move along a horizontal, circular path while rotating about their radial axes. This combination of reflector array movement coupled with the large number of individual reflectors in each array produces a large number of widely scattered reflection paths. The motor is preferably powered by a set of internal solar cells, but it may also be powered by an internal battery or external electric power.
