A plurality of light emitting diodes are arranged on the backboard in a gridding way. The light emitting diode is arranged at the peak of each grid; wherein the light-reflecting device is a light-reflecting column arranged among the light emitting diodes on the backboard. The utility mode also provides a light box which comprises a backboard and a picture support plate arranged at a light box exhibition direction. A plurality of light emitting diodes are arranged on the backboard in a gridding way. The light emitting diode is arranged at the peak of each grid; wherein a light-reflecting column is arranged among the light emitting diodes on the backboard. The light-reflecting device can effectively eliminate the dark area of light box picture, reduces material consumption, homogenizes the light to the greatest extent, and improves the homogeneous degree of the light on a light box exhibition surface. |
