Abstract: An electronic display which can be mounted above a paved surface in an outdoor environment. A surface or plate is placed behind the electronic display to define a gap where cooling air can be drawn through said gap in order to cool the electronic display. A plurality of ribs may be placed within the gap and in thermal communication with the electronic display. The density of the ribs may be varied according to the inlet and exhaust openings for the cooling air. The ribs may be placed at a higher density near the exhaust to account for the increase in temperature of the cooling air as it travels through the gap.

Abstract: A system for cooling an electronic display where an isolating structure may be used to allow ambient air to cool power modules. The isolating structure substantially prohibits contaminants which may be present within the ambient air from contacting sensitive electrical components on the power modules or otherwise. A gasket may be used to seal the interface between the power modules and the isolating structure. Heat sinks may be placed in thermal communication with the power supplies and fans may draw air through a narrow channel in which the heat sinks are located. In some embodiments the narrow channel may have the opposing surface of the channel defined by the rear portion of an LED assembly. Exemplary embodiments may use the ambient air to cool both the power modules and a closed loop of isolated gas within the electronic display.

Abstract: The invention is intended to provide a lighting device that shortens time required to obtain peak brightness. A backlight unit 16 according to the invention includes: cold cathode tubes 22 as a light source; a chassis 18 housing the cold cathode tubes 22; a reflection sheet 21 disposed within the chassis 18 and reflecting light; and a heat insulator 27 disposed between the chassis 18 and the reflection sheet 21.

Abstract: A system for cooling an electronic image assembly using ambient gas. The system contains a plurality of channels place behind the electronic image assembly and preferably in conductive thermal communication with the image assembly. Ambient gas is ingested into the display housing and directed to a first manifold which distributes the ambient gas to the plurality of channels. A second manifold preferably collects the ambient gas from the channels after absorbing heat from the electronic image assembly and/or channels. The second manifold then preferably directs the ambient gas towards an exhaust aperture and out of the display housing. Circulating gas may also be used to cool a front portion of the electronic image assembly. A cross through plate may be used to allow the ambient gas and circulating gas to cross paths without mixing.
