PROBLEM TO BE SOLVED: To change the color of light of each element, which forms letters and figure, to the natural color thereof by supporting a hollow lantern on a board with a translucent wall material, and arranging a light emitting tool inside of the lamp, and drawing a figure with the fluorescent coloring agent on the translucent wall material, and connecting the light emitting tool to a power source through a controller. SOLUTION: A lantern 20 is formed by wrapping a translucent thin film into a cylindrical shape and drawing required letters and figures thereon. A light emitting tool 25 is a kind of a fluorescent lamp, and formed into a bar- shape, and arranged in the same axis with an axis of the lantern 20. When an electric switch 36 is turned on, electricity at 6 V of direct current, which is supplied from a dry battery 34, is converted to the electricity at 100 V of alternating current through a booster, and intermittently applied to the light emitting tool 25 through a control board so as to flash the light emitting tool 25 with the predetermined interval. Partitioning walls are rotated so as to change the light to be applied to the letters and figures, which are drawn on the lantern 20, and color of the letters and figure drawn on the lantern 20 is thereby changed. |
