ABSTRACT:
A color wheel assembly includes a color wheel and a driving motor. The color wheel is attached directly to a hub of the driving motor. Consequently, no additional components are required to fix the color wheel to the driving motor, thereby reducing the number of components and the number of manufacturing processes. Thus, the color wheel assembly as a time-share light dispersing device can be inexpensively manufactured with a high degree of precision.
