ABSTRACT:
A vertical storage and retrieval system has a light bar at the operator's station that visually indicates selected bins on a conveyor shelf. The light bar comprises an elongated rectangular tubing flush with the work surface. Several identical electric modules are connected end-to-end and inserted into the tubing. Each module has an array of parallel circuits, each containing a light emitting diode, connected to an electric source. Through circuits connect the terminal circuit of each array of parallel circuits to an electrical sink. A branch circuit of each parallel circuit connects with the corresponding parallel circuit on the adjacent module. The circuits are arranged such that the end module remote from the electric source and sink may be severed and a portion of the module discarded without affecting the operation of the light bar.
