In general lighting devices, the brightness on the irradiation surface is changed by controlling the light quantity of the light source, and a plurality of light sources having different emission colors are used as the light source. By controlling each, the light color on the irradiation surface irradiated with the light from a plurality of light sources is changed. Such a dimming method can automatically change the light amount and the light color, but the configuration and control become complicated. Therefore, an illumination device capable of dimming with a simpler configuration is desired.

  FIG. 17 is a schematic partial enlarged cross-sectional view of a lighting device using the decorative frame 1c according to the fourth embodiment. FIG. 18 is a schematic partial enlarged front view of the lighting device. Note that the lighting device has the same structure as the lighting device described in Embodiment 1.

In addition, a filter that is uniformly colored in one color may be used. In this case, there is an advantage that manufacture is easier than coloring the transmission plate.

  Further, the filter may be formed so that the transmittance in the circumferential direction is continuously changed between high and low. In this case, since the amount of light transmitted through the filter changes according to the rotation of the filter, the brightness on the irradiation surface can be changed steplessly. Further, the degree of light scattering may be changed according to the circumferential position.

  In addition, a polarizing filter that cuts light other than a predetermined direction may be used in order to reduce the amount of light reflected by glass, water surface, etc. in the direction of light emission from the light source to prevent reflection of light. . Further, the light emission direction may be changed by using a sheet in which different lenses and prisms are arranged in the circumferential direction.

  In the present embodiment, the filter 51 is formed so that the color density, color type, transmittance level, and the like are changed in the circumferential direction. It may be formed so as to change color shading or the like, or the filter and the transmission plate may be formed so as to have different characteristics.
