Abstract: A light generating base includes a motor having a motor shaft with upper and lower portions that project upwardly and downwardly from a motor body. The lower portion of the motor shaft is secured to a stand such that the motor body is rotatable relative to the stand about a vertical axis. A lamp unit is mounted on the upper portion of the motor shaft, and is operable so as to radiate light upwardly. An upright filter supporting member has a lower portion that is secured to the motor body, and an upper portion that projects upwardly beyond the lamp unit. A color filter disk is mounted on the upper portion of the filter supporting member so as to be co-rotatable therewith, and is disposed above the lamp unit and transverse to a light radiating direction of the lamp unit. The color filter disk is formed with a plurality of differently colored angularly displaced light filtering regions.
