Claim 0:
1. An illumination assembly for a vision system having a housing that encloses optics and a sensor receiving light from an imaged scene at the optics comprising:
a cover having a light-transmissive face that defines a forward-facing exterior surface of the cover, the cover having therein an illumination component having a plurality of lighting elements, the cover defining a window through which light passes into the optics from the imaged scene and the lighting elements arranged to direct light through the light-transmissive face at locations around the window onto the imaged scene, wherein the cover comprises a plurality of light-transmissive sidewalls, the light-transmissive sidewalls defining a multi-sided polygonal shape, the cover being configured to receive a removable wall structure that bounds the window and directs light from the imaged scene into the optics;
a fastening assembly that removably secures at least two corners of the cover to the housing; and
a connector assembly that interconnects processing circuitry that controls the lighting elements to circuitry in the housing so that control signals and power from the housing are transmitted to the illumination assembly.
