Power for an illumination device and a camera is provided from power integrated onto a data cable between a controller/computer and the light illumination device. The camera—controller/computer interface includes one of GEV with PoE, USB and CXP, where a power is provided within the data interface cable, and the distance between the camera and the controller/computer is very long. In order to avoid running multiple long cables in a production manufacturing environment, a power extraction module is incorporated into a light illuminator, in order to extract the power for the interface cable, and to generate the individual powers for the light illuminator and the camera. In cases where the interface standard does not provide integrated power, power can be injected to the cable and extracted from the light illumination module. |

1. A light illumination apparatus comprising:
a first connector adapted to receive an integrated power and data stream from an external controller, the integrated power and data stream having a source power component at a source voltage combined with a data stream component on a conductor of the first connector; an illumination module generating light upon receiving a first power component at a first voltage; a second connector adapted to communicate the data stream component with an external camera apparatus for modulating the data stream component with a digital representation of a received image upon receiving operating power from a second power component; a power extraction module coupled to the first connector, the second connector, and the illumination module, the power extraction module adapted to
extract the source power component from the integrated power and data stream,extract the data stream component from the integrated power and data stream,communicate the data stream component between the first connector and the second connector,convert a first portion of the source power component to the first power component at the first voltage,apply the first power component to the illumination module,supply a second portion of the source power component to the second power component,provide the second power component to the external camera apparatus; and a housing adapted to house the first connector, the illumination module, the second connector, and the power extraction module. |
