TITLE Back-lighted Display Panel for Coolers ABSTRACT A back-lighted illuminated sign includes a vented light cabinet having a light-transmitting front panel aperture, with side, top, bottom, and rear cabinet panels arranged in light-source-surrounding, cabinet-interior-defining relation; and wherein said bottom panel includes passive vent openings for admitting a thermally induced draw of cooler ambient air flow there through into the cabinet's interior. The rear panel includes vent openings arranged adjacent the top panel, for exhausting thermally-induced air flow, at a first temperature, from the cabinet's interior. The cabinet includes spacers for spacing the cabinet from an adjacent freezer in chimney defining relation between the rear panel and an exterior panel of the freezer, with air flow admitting and exhausting openings at the lower and upper ends, respectively, of that chimney. The chimney is thereby adapted to channel a secondary thermally-induced air flow, having a second temperature lower than said first temperature, between the rear panel and the freezer panel.
