(Background Art) Conventionally, incandescent light bulbs, fluorescent lamps 1, and the like have been widely used as light sources. The emitted color of these light sources is usually
Each light source is unique, and it is impossible to achieve multiple emitted colors with one light source (1). Therefore, if you want to vary the light color of illumination in the same illumination space, A method is used in which a plurality of light sources emitting light of different colors are installed together and each of these is blinked or dimmed.

Such a conventional example is shown in FIGS. 1 and 2. In Fig. 1, la and Ib are two color incandescent light bulbs with different ladles attached, and these are placed in a case 2 with light transmitting and diffusing properties (for example, frosted glass). There is. Similarly, FIG. 2 shows three fluorescent rungs 3a, 3b, 3 each coated with a fluorescent substance of a different luminescent color.
c is arranged inside the light transmitting diffusion case 4. All of these attempts to obtain light emitted from multiple color light sources within the case as mixed color light using a light-transmitting and diffusive case. However, with such conventional methods, improving color mixing generally results in a greater loss of transmitted light, and conversely, improving transparency means that the colors emitted from each light source inside the case can be seen through, and color mixing is not sufficient. There was a contradictory problem that it was not done.
