Abstract:
1. An apparatus comprising a system for detecting containers that exhibit features arranged on a container wall thereof, said system comprising an optical assembly comprising a camera, and an illuminating unit comprising a plurality of light sources arranged on a plurality of conductive tracks, said light sources, when viewed in a vertical direction of said illuminating unit, being arranged one above the other in vertical columns such that said light sources project a strip-shaped light beam onto a container-wall region of said container wall, said projected strip-shaped light beams being disposed at a distance from one another when viewed in an axial direction of said illuminating unit, wherein said light sources, are, when viewed in axial direction, arranged on said conductive track one above the other without offset, wherein each vertically aligned column of light sources is actuated via a control unit that is configured such that said vertically aligned columns project a light pattern onto said container-wall region that is variably adjusted as a function of surface properties of said container-wall region, said illuminating unit comprising a first light source set on a first vertically aligned column and a second light source set on a second vertically aligned column that is horizontally adjacent to said first vertically aligned column, each of said first and second light source sets comprising at least one light source, wherein said adjustment is effected by switching said first light source set between an on state and an off state concurrently with switching said second light source set between an on state and an off state.
