Abstract: A projector includes a lens, a beam processing module, a plurality of digital micromirror devices, a reflecting module and an illumination module. The beam processing module is disposed with respect to the lens. The digital micromirror devices are disposed around the beam processing module, wherein a beam projecting path is defined between the lens and the digital micromirror device. The reflecting module is disposed with respect to the digital micromirror devices and located beyond the beam projecting path. The illumination module is disposed with respect to the reflecting module. An initial beam projected by the illumination module is reflected to the digital micromirror devices by the reflecting module, such that the digital micromirror devices generate a plurality of image beams. The beam processing module combines the image beams to form a projecting beam and projects the projecting beam onto the lens along the beam projecting path.

The light source module provides a first beam. The wavelength conversion module includes a reflecting plate and a wavelength conversion layer. The dichroic filter reflects a first part of the first beam to form a second beam, and a second part of the first beam can pass or detour the dichroic filter to form a third beam. The second beam is condensed by the first collimator lens and projected onto the wavelength conversion layer to excite a fourth beam. The third beam is condensed by the second collimator lens and projected onto the reflecting plate to reflect a fifth beam. The fifth beam is reflected via the reflector and the dichroic filter to mix with the fourth beam.

Abstract: A projector including a light source, a first prism, a second prism and a digital micro-mirror device (DMD) is provided. The light source emits light. The first prism includes a first surface, a second surface and a third surface which are connected to each other around the perimeter thereof, and the illumination light enters the first prism through the first surface. The second prism has a fourth surface and a fifth surface which are connected to each other, and the fourth surface faces the second surface of the first prism. The DMD faces the third surface. The illumination light sequentially passes through the first surface, is reflected by the second surface, passes through the third surface, and reaches the DMD. The DMD converts the illumination light into image light, and the image light sequentially passes through the third surface, the second surface, the fourth surface and the fifth surface.

Abstract: The invention provides a projector with a biaxially-tilted (with a 17-degree tilting angle) digital micro mirror device (DMD) whose light source module and lens set deployment is improved so that the incident light provided by the light source module travels along a first light route and is enlarged by the lens set before traveling along a second light route and provided to the biaxially-tilted DMD. The projector features in that the first lens group is composed of two specific spherical lenses or one specific aspheric lens and the second lens group is composed of one aspheric lens. Therefore, the prismless, non-telecentric projector, without using any TIR prism, can be made with fewer components, lower cost, and enhanced efficiency.

Abstract: A light integrating system includes an integrator rod, a triangular prism, and first and second light sources misaligned with each other. The integrator rod has a light-integrating axis, first and second light-entrance surfaces, a first reflection inclined surface and a first light-exit surface. The triangular prism adjacent to the second light-entrance surface has a third light-entrance surface, a second light-exit surface, and a second reflection inclined surface. Light of the first light source is incident into the integrator rod through the first light-entrance surface and is reflected by the first reflection inclined surface to emit out of the first light-exit surface along the light-integrating axis. Light of the second light source is incident into the triangular prism through the third light-entrance surface and is reflected by the second reflection inclined surface to emit out of the first light-exit surface through the second light-exit surface and the second light-entrance surface sequentially.
