Patent ID: 8344668

Claim:
A method for controlling an LED illuminator by an optical signal propagated jointly with electric power feed via one of a plug-in socket and a thread socket used for one of light bulbs and lamp assemblies including an optical access with attachment for securing a terminated end of an optical cable, wherein said optical access of said thread socket includes one of a hole and a cutout in a rear contact of said optical access aligned with said access about the longitudinal axis of said thread socket; said optical signal is propagated from a controller via said optical cable selected from a group comprising a lightguide, a fiber optic and a combination thereof and said electric power is fed via at least one of materials selected from a group comprising power wires, power cables, cables combining said optical cable and power wires, electrical conduits, electrical boxes, mechanical power switches, semiconductor power switches, dimmers, power relays, power sockets, power plugs, current sensors, power adaptors, power supplies, bulb sockets, lamp sockets and combinations thereof; said illuminator includes one of an optical receiver and optical transceiver with said optical access directed toward said terminated end, said controller includes one of an optical transmitter and an optical transceiver with said optical access for propagating said optical signal via said optical cable, said method comprising the steps of: a. terminating said optical cable end for providing an optical path to said optical signal; b. securing said optical cable end to said access via said attachment; c. connecting said socket to said electric power via said materials; d. mounting said illuminator to said socket; and e. propagating said optical signal for operating said illuminator.
