A light distribution system is used in a method for converting solar or artificial light into electricity by collecting, concentrating and time-sharing light to a number of photovoltaic cells. A convergent lens and an optional optical collimator provide an intense parallel beam directed onto a spinning mirror reflecting the beam in a radial plane to its axis of rotation and time-distributing it to a number of photovoltaic cells which are in an inside surface of a cylinder in the plane. The apparatus has DC or AC output capability, in accordance with the connecting pattern of the PV cells and is protected against burnout due to spinning mirror failure by stopping the beam at a window. A light pipe can be used to carry the light from the collector to the mirror. The device can be used to transmit power in a laser beam to a remote station such as a robot. The same concept of distributing collimated natural or artificial light can be used where the receivers are optical fibers instead of PV cells to supply a series of lighting fixtures fed by the same collector |
