Abstract
A color wheel comprises sectorial color filter segments and a support member. Protrusions are disposed at the support member and engaged with either through-holes or cavities as segment fixing mechanisms formed at the color filter segments, whereby the color filter segments are fixedly positioned with respect to the support member in the radial direction. Consequently, the color filter segments can be surely prevented from getting scattered off when the color wheel spins at high speed.
