摘要

PROBLEM TO BE SOLVED: To provide an internal illumination type light box capable of efficiently reflecting light of LEDs, and excelling in workability.

SOLUTION: In this internal illumination type light box, a plurality of LEDs and a reflecting plate reflecting the light of the LEDs are arranged in a box body with a front face opened, and the front-face opening of the box body is covered with a light diffusion plate. The light box is structured such that the reflecting plate is formed as a reflective tray formed into a tray type having a bottom part and a sidewall part rising from the bottom part by sheet molding; the reflective tray is arranged in the box body so that its bottom inner surface faces the front side; and the LEDs are arranged inside the sidewall part of the reflective tray.
