摘要： A laser projection apparatus includes a reflecting unit, a reflecting diffuser, a first lens array having a length and a width, a condensing lens having first and second lens portions and first and second center axes, a laser set emitting a first color light, an imaging module, and a projection lens. The reflecting unit reflects the first color light to the first lens portion. The reflecting diffuser reflects the first color light to travel along a light-exit axis of the second lens portion. The first lens array is disposed on the light-exit axis. The length along the first center axis and the width along the second center axis are less than or equal to one half of a diameter of the condensing lens and the diameter, respectively. The imaging module is disposed on the light-exit axis. The imaging module and the projection lens receive the first color light sequentially.

摘要： A projector includes a light source module, a collimator lens module, a wavelength conversion module, a first dichroic unit and a second dichroic unit. The light source module provides a first beam. The collimator lens module has a first part and a second part. The first beam passes the first part. The wavelength conversion module receives the first beam and includes a reflecting plate and a wavelength conversion layer. The first dichroic unit reflects the first beam. The reflecting plate reflects the first beam to generate a second beam passing the second part. The wavelength conversion layer is excited by the first beam to generate a third beam. The second dichroic unit allows passing of the third beam and a part of the second beam to generate a fourth beam, and reflects the other part of the second beam to generate a fifth beam.

摘要： A projector includes a collimator lens, a, a light transmission component and a solid-state light source. Amounts of the dichroic lens and the solid-state light source are plural. The dichroic lens and the light transmission component reflect beams with specific wavelength, and allow passing of beams with other wavelength. The solid-state light source emits the beams to the corresponding dichroic lens. The projector utilizes the dichroic lens and the light transmission component to pass the beams with different base color uniformly through the first part and the second part of the collimator lens. The projector further includes a polarized lens, a reflection lens and a phase retardation unit. The phase retardation unit transforms polarization of the beams, and the polarized lens reflects some polarized beams and allows passing of other polarized beams to combine a plurality of alignment modules for providing uniform illumination.

摘要： 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.

摘要： A color wheel used in a projector includes X color blocks and Y filter blocks; therein, X is an integer equal to or larger than 3. The X color blocks are defined to be arranged in an annular direction by repeating (N-1) times; therein, N is an integer equal to or larger than 2. The light permeability characteristics of the X color blocks are distinct from one another. The X color blocks correspond to X light colors respectively. The X color blocks are substantially equal in area. The Y filter blocks are formed of the X color blocks. The Y filter blocks correspond to the X light colors. One of the Y filter blocks is formed by two color blocks of one of the X color blocks.
