A light box using LEDs(Light Emitting Diodes) is provided to irradiate the light from a light emitting unit to a side portion of a waveguide by mounting the light emitting unit on a frame and assembling the waveguide on the light emitting unit. A light waveguide plate is mounted on a bottom surface(11). A container holder is arranged behind the bottom surface to be apart from the waveguide plate. A light emitting unit(30) is contained in the container holder. The container holder is formed by a partition. A step difference is formed by the partition. A cover plate, which is mounted behind the waveguide plate, is mounted on the step difference. A frame is assembled by a connecting unit(17). An advertisement sheet is formed in front of the waveguide plate. A transparent plate is formed in front of the advertisement sheet. |
