PURPOSE:To have uniform illuminating effect without uneveness by continuously varying various independent colors and mixture thereof automatically through the action of a color filter, which rotates simultaneously with a fluorescent lamp. CONSTITUTION:Outside circumference of a color filter cylinder 28 made of a transparent or translucent material is divided into four equal widths, and differently colored filters 2 are installed at an equal spacing. Fixtures 23, 24 are provided at the two ends of a frame 22, and a fluorescent lamp stabilizer 24 is mounted inside of the fixture 23. A supporting tool 3 having a switch cam 21 and pulley 11 mounted on a shaft cover 46 is embodied in a structure, in which the color filter 28 rotates when a motor 12 is operated. Thereby a highly uniform illuminating effect is obtained with a wider light source, which provides less shade and less unevenness in illumination. It is practicable to form any desired hue and pattern by means of coloring or fitting of a filter film. |
