  • Publication number: 20110164407
    Abstract: A display case having end jamb lighting module and a center mullion lighting module is disclosed. The lighting modules include a shell and at least one substrate whereon lighting elements are mounted. The shell defines engagement slots used to affix the substrate to the shell. The shell defines an aperture allowing light from the lighting elements to be projected out. The lighting module may include a second substrate upon which electrical components are mounted, the electrical components for conditioning input power for the lighting elements. A reflective portion of the shell or a separate reflector mounted on the shell operates on the light to form a desired spatial distribution of light. An optical cover covers the aperture. The center mullion lighting module can include a third substrate for mounting of lighting elements. Alternatively, the center mullion lighting module can be formed by combining two end jamb lighting modules.
