ABSTRACT:
Heat build up is reduced in x-ray film illuminator apparatus by transferring excess heat from the sources thereof to the exterior of the unit and then into the surrrounding environment. A heat dispersing surface contacts the hottest part of the ballast employed within the unit, with a back wall of the unit itself being spaced from an associated wall, on which the apparatus may be detachably mounted on a special hanger so as to permit a vertical air flow path between the back wall and associated mounting wall surface. A viewing area of the unit is formed by a translucent face plate retained in position along at least the top or upper peripheral portion thereof by a resilient element also capable of retaining in place the film transparency or other media that is being viewed.
