ABSTRACT:
A photo-control apparatus comprising a photo-control circuit that includes two or more photo-cells connected in parallel that respond to ambient light. The circuit includes a switch that connects a power source to a load. When the photo-cells are exposed to ambient light, current flows through the parallel photo-cells operating the switch which disengages the load from the source. The plural parallel photo-cells in the photo-control circuit provide for improved reliability and have the potential to cost less to manufacture than a single photo-cell as used in a conventional photo-control circuit.
