Sign ventilation system

An electronic sign, comprising a plurality of ventilated electronic sign modules, the modules being substantially aligned in a horizontal direction and each module being disposed horizontally adjacent to one or two other said modules, each said module including:

• a substantially planar-shaped lighting module configured to emit light that is visible to a viewer of the sign;
• a cabinet supportingly engaging the lighting module, the cabinet having a bottom portion, a rear wall, two opposing side walls, a top wall and a bottom wall, the rear wall being disposed opposite the lighting module such that an air chamber is defined between the cabinet and the lighting module;
• a substantially vertical partition disposed within the air chamber and extending between the bottom wall and the top wall, and between the lighting module and the rear wall, the partition dividing the air chamber into a first section and a second section;
• and
• an electric fan disposed within the cabinet or the lighting module and configured to transfer air from the first section to the second section;
• wherein the cabinet and/or the lighting module have a plurality of throughholes disposed at the bottom portion and fluidly interconnecting the air chamber to ambient air, a first subset of the throughholes fluidly connected to the first section, a second subset of the throughholes fluidly connected to the second section;
• and
• wherein the electric fan draws air from outside the cabinet through the first subset of throughholes and into the first section, said air traveling through the first section and into the second section before exiting the second set of throughholes.
