Abstract
A display case having lenses mounted in the case that distribute or direct light emitted by fluorescent tubes located near the ends of display shelves toward the shelves in order to provide a more uniform light distribution along the length of the shelves. The lenses facilitate the illumination of items placed on the shelves near the front and middle of the shelves. Light-directing portions of the lenses distribute or direct light emitted from the fluorescent tubes located inside the lenses toward the display case shelves. In another embodiment of the display case, the lenses are mounted horizontally inside the case, and used to direct light toward the interior of the case and toward the shelves inside the case. In still another embodiment of the display case, the lenses are mounted vertically inside the case and at the corners of the case.
