Zusammenfassung: | PROBLEM TO BE SOLVED: To sufficiently control a change of colors of light of illumination by providing an electric power supply control means to control electric power supply to plural light sources provided not to be seen from outside through a transmission means and a light source by a light source electric source in the inside of a hollow spherical body. SOLUTION: An amplifier 10 which is a control means to control electric power to be supplied from an electric bulb 30 to miniature lamps 1, 2, 3 is provided. A shading plate 5 arranged to make any of the miniature lamps 1, 2, 3 in the inside of a hollow spherical body 7 unseen from a transmission plate 4. Consequently, any of light transmitted by each of the miniature lamps 1, 2, 3 does not strongly influence in light taken out especially from the transmission plate 4, it is reflected on a white color inwall 7a of the hollow spherical body 7, accumulated and additive color mixed. The color of light produced as a result of additive color mixture is decided in accordance with a mixing ratio of each of the colors of the miniature lamps 1, 2, 3. |
