A shelving system includes at least one vertically oriented shelf rail having a row of vertical slots leading to the shelf rail interior. In the interior, a bus bar includes conductors. A carrier element, such as a shelf element, is mounted on a bracket configured to hook into the shelf rail slots. A lighting device is attached to the carrier element or the bracket. A current collection device is fastened to the bracket and includes tap contacts that protrude from a housing and are disposed on the engagement section of the bracket. The tap contacts are resilient and disposed to be elastically pressed into the housing against a spring force when the bracket is being hooked into the shelf rail, pressed out of the housing when located in the shelf rail interior, and pressed against associated current conductors to establish an electrically conducting connection for the lighting device.
