Patent ID: 6999252

Claim:
A color wheel comprising: a carrier; a color filter assembly mounted coaxially on said carrier and formed by a plurality of annularly arranged filter segments, said color filter assembly defining an inner periphery extending around an axis of said carrier, an outer periphery extending around said inner periphery, an upper surface and a lower surface extending between said inner and outer peripheries, and an engaging element projecting axially from one of said upper and lower surfaces; a press cover connected to said carrier to press said filter segments against said carrier; and a limiting element projecting axially toward said engaging element from one of said carrier and said press cover to engage said engaging element so as to prevent said color filter assembly from displacing radially from said axis of said carrier due to a centrifugal force, wherein said carrier has a central boss, said engaging element being formed as an annular flange, which projects from said upper surface proximate to said inner periphery and which has an outer peripheral face extending circumferentially around said central boss.
