There is provided an illuminating display device for use with a mosaic panel, in which necessary display devices, measuring instruments, and the like are mounted to a cross-wise-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 illuminating display device comprises a base frame (4) mountable to and removable from the grid, a circuit board (5) and a reflector (6) to be mounted on the base frame. The base frame (4) comprises 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 an engaging claw (4c), and a base seat (4a)on which a circuit board and further means 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 and dissipated. <IMAGE> |
