Abstract: As regards a surface light source device for use with back-light or the like of a transmissive display panel, the efficiency of the cooling structure for the device will be improved and dust and dirt will be prevented from adhering. The surface-light source device has a housing, a diffuser panel, a reflective plate, lamps, and an electric circuit portion. The housing has a window portion located ahead, a base portion located behind and side portions forming a flat space by connecting the two. The diffuser panel is mounted to the window portion of the housing. The reflective plate is supported by the side portions and partitions the flat space into a closed space ahead and an open space behind to be interposed therebetween. The lamps are housed in the closed space, and are positioned right above the reflective plate and right under the diffuser panel to radiate light toward the diffuser panel. The electric circuit portion is housed in the open space, and is electrically connected to the lamps to light them up. On the side portions of the housing, there are formed openings, through which cooling air supplied from outside is introduced into the open space to diffuse heat accumulated within the housing.

Abstract: A display assembly with condensation control includes an electronic display and airflow pathway located within the housing. At least one sensor is located along said airflow pathway. A controller in electronic communication determines a local dewpoint and an internal temperature for the display assembly based, at least in part, on data received from the at least one sensor, calculates a dewpoint spread between the dewpoint temperature and the internal temperature, and initiates modified operations where said dewpoint spread is less than a predetermined threshold.

Abstract: Disclosed herein is an electronic display assembly having a thermally conductive housing and an image assembly. The image assembly is positioned within the thermally conductive housing and behind a transparent plate assembly. An inlet opening and outlet opening are formed by gaps located between opposing edges of the image assembly and the housing. A space between the image assembly and the plate assembly forms a channel. Thermally conductive plates extend from near the image assembly within each of the inlet opening and outlet opening to contact the housing. Heat from the image assembly is conductively transferred to the housing by the thermally conductive plates. A fan may be positioned to circulate cooling air through the channel via the inlet and outlet openings and apertures in the thermally conductive plates.
