摘要： Disclosed is an illuminating display device for use with a mosaic panel, in which necessary display devices, measuring instruments, and the like are mounted to a crosswise-shaped metallic grid, to form a panel surface, and on which light-emitting diodes are arranged at a high density to afford a high-luminance display surface. The illuminating display device prevents the display surface and the interior of the display device from increasing in temperature to high due to heat generated by a large number of light-emitting diodes. The whole illuminating display device is composed of a base frame (4) mountable to and removable from the grid, and a circuit board (5) and a reflector (6) to be mounted on the base frame. The base frame (4) is composed of a leg (4b), which is in face-to-face contact with a partitioning wall (2a) of the grid and which is engaged with the grid by its engaging claw (4c), and a base seat (4a) on which a circuit board and others are mounted, wherein the base seat (4a) and the leg ( 4b) are made of metal and integrally provided. By this arrangement, heat generated by illumination of the light-emitting diodes is conducted via the base frame to the metallic grid, thus effectively radiated as a whole.
