Optical module for use in a projector apparatus and projector apparatus

摘要

An optical module includes a curved reflecting component, a first filtering component, a second filtering component and a rolling component. The curved reflecting component has a focus, a transmissive portion, a first reflecting portion and a second reflecting portion. The rolling component includes a first transforming portion and a second transforming portion. The first waveband light is transmitted into the transmissive portion and is then transformed into a second waveband light via the first transforming portion. The second waveband light is subsequently transformed into a first emergent light. The first waveband light is transmitted into the transmissive portion and is then transformed into the second waveband light via the second transforming portion. The second waveband light is subsequently transformed into a second emergent light.

1. An optical module for use in a projector apparatus, the optical module comprising:
a curved reflecting component, which has a focus, a transmissive portion, a first reflecting portion and a second reflecting portion, and the transmissive portion being disposed on the first reflecting portion; a first filtering component; a second filtering component disposed at a side of the first filtering component; a rolling component, which includes a first transforming portion and a second transforming portion, each of the first transforming portion and the second transforming portion comprising a wavelength transforming unit, and the first transforming portion and the second transforming portion independently passing through the focus in a first period and a second period; a reflecting component disposed between the curved reflecting component and the first and the second filtering components; and a first collecting component disposed between the reflecting component and the first and the second filtering components, wherein, in the first period, a first waveband light transmits into the transmissive portion and then is transformed into a second waveband light via the first transforming portion, and the second waveband light is transformed into a first emergent light via the second reflecting portion and the first filtering component, and in the second period, the first waveband light transmits into the transmissive portion and then is transformed into the second waveband light via the second transforming portion, and the second waveband light is transformed into a second emergent light via the first reflecting portion and the second filtering component.
