Abstract
A color light generating assembly includes a color wheel module and a reciprocating module. The color wheel module includes a color wheel and a first driving device. The color wheel is disposed on a transmission path of an illumination beam of the projection apparatus. An optical axis of the illumination beam irradiates the color wheel along a predetermined direction. The first driving device is configured to drive the color wheel to rotate so as to sequentially convert the illumination beam into a plurality of sub-illumination beams of different colors. The reciprocating module is connected to the color wheel module and configured to drive the color wheel module to reciprocate along a predetermined path when the color wheel is being driven to rotate by the first driving device. The predetermined direction is non-parallel to the predetermined path. A projection apparatus using the assembly and a projection method are also provided.
