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 circuit are arraged 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.

Claims4

Dependent claims

A method of providing a light bar for visually indicating a selected location along an elongated path comprising the steps of:

a. providing an electric energy source and an electric energy sink;
b. providing a housing with openings therein;
c. cutting the housing to a length corresponding to the elongated path;
d. providing a plurality of electric modules, each electric module having an array of parallel circuits, each parallel circuit containing a light emitting diode and being energizable independent of all the other parallel circuits, the light emitting diodes being spaced to suit the housing openings;
e. connecting the electric modules in end-to-end connection to create a first end module and a second end module;
f. severing the second end module such that the overall combined length of the modules is approximately equal to the housing length;
g. inserting the electric modules in the housing;
and
h. connecting the first end module to the electric source and the electric sink.
