Patent ID: 8148921

Claim:
A method for propagating optical signal jointly with electric power feed to at least one of LED illuminators and electrical appliances from control devices selected from a group comprising keypads, touch screens, switch-controllers, relay-controllers, lighting controllers, dedicated controllers, home automation controllers, video interphone monitors, shopping terminals, signal distributors, IR drivers, command converters and combinations thereof; said optical signal is propagated via at least one optical cable selected from a group comprising lightguide, fiber optic and a combination thereof jointly with said electric power fed via at least one of materials selected from a group comprising power wires, power cables, power cable assembly with power plug, power cable assembly with power plug and socket, combination cable including said optical cable and power wires, said combination cable assembly with power plug and optical access, said combination cable assembly with power plug and socket each with optical access, electrical conduits, electrical boxes, power sockets, power sockets with optical access, power plugs, power outlets, power switches, power relays, current sensors, power adaptors, light bulb sockets, lamp assemblies and combinations thereof; at least one of said control devices includes an optical transmitter with an optical first access and a first attachment for securing a terminated end of said optical cable to said first access and said at least one of LED illuminators and electrical appliances includes an optical receiver with an optical second access and a second attachment for securing one of the other terminated end and the last terminated end of a cascaded chain of said optical cable to said second access; said optical signal is propagated from said transmitter to said receiver via one of a single stretch and a plurality of cuts of said optical cable, wherein said cuts are optically linked in said cascaded chain through at least one of said materials and a mating adaptor, wherein each of the ends of said cuts are terminated and linked through a mating combination selected from a group comprising an access in said materials, a terminated end of another cut in said materials and a terminated end of another cut in said mating adaptor, said method comprising the steps of: a. terminating all the ends of one of said single stretch and said cuts for linking said cuts in said cascaded chain; b. securing said one terminated end of one of said single stretch and said cascaded chain to said first access and said one of other terminated end and last terminated end to said second access; c. connecting said at least one of LED illuminators and electrical appliance to said electric power via said materials; and d. propagating said optical signal selected from a group comprising control, commands, continuous on, pulse train and combinations thereof from said at least one of control devices to said at least one of LED illuminators and electrical appliances.
