摘要： The present invention provides a color wheel including a motor and a color filter module. The color filter module includes a first color filter having a first transmittance and a second color filter having a second transmittance that is smaller than the first transmittance. 50% of the first transmittance is corresponding to a first light wavelength and a second light wavelength that is larger than the first light wavelength. The second color filter and the first color filter have substantially same hues. 50% of the second transmittance is corresponding to a third light wavelength and a fourth light wavelength that is larger than the third light wavelength. The second color filter satisfies a first condition chosen from the third light wavelength being larger than the first light wavelength or the second light wavelength being larger than the fourth light wavelength.

The DMD having a common plane and micro mirrors disposed on the common plane is disposed on a transmission path of the illumination beam to convert an illumination beam from the illumination system into an imaging beam into a screen. The imaging system includes a projection lens disposed on a transmission path of the imaging beam and a total internal reflection (TIR) prism disposed between the DMD and the projection lens. The projection lens has an optical axis, which is not parallel to a normal vector of the common plane and a chief beam of the imaging beam. At least one of the normal vectors of the surfaces of the TIR prism opposite to the projection lens and the DMD is not parallel to the optical axis.

摘要： A projection apparatus includes at least one light source, a field lens, a light valve, and a projection lens. The light source provides an illumination beam. The field lens is disposed in a transmission path of the illumination beam including an effective beam passing through the field lens and a ghost beam reflected by the field lens. The effective beam forms a light spot on the light valve capable of converting the effective beam into an image beam. The projection lens is disposed in a transmission path of the image beam and a ghost beam path of the ghost beam. A center of the light spot does not overlap a center of the light valve. An offset direction from the light valve to an optical axis of the projection lens is the same as a direction from the center of the light valve to the center of the light spot.
