ABSTRACT:
A lighting apparatus is provided which comprises a color disc capable of transmitting light therethrough and arranged within a housing having an opening. The color disc has a planar surface parallel to the opening, and a large number of subdivided sections defined on the planar surface. The subdivided sections are individually colored in one of a plurality of colors such that, when viewed as a whole, the planar surface has a plurality of identical coloration patterns each consisting of the subdivided sections of the same color and that any adjacent ones of the coloration patterns are different in color from each other. A shutter disc is arranged between the color disc and the opening and has a large number of windows for permitting only those subdivided sections forming one of the coloration patterns to be exposed to the outside of the housing when the shutter disc is at a predetermined rotational angle position. The lighting apparatus further comprises a motor for rotating the shutter disc, and an illuminating bulb arranged at the opening for radiating the light from the opening to the outside of the housing.
