摘要： A beam splitter/combiner includes a first light-transmitting substrate, a first light transmission element, and a second light transmission element. The first light-transmitting substrate has a first optical surface facing incident light and a second optical surface opposite to the first optical surface. The first light transmission element is disposed on the first optical surface. The second light transmission element is disposed on the second optical surface. A first color beam incident on the first light-transmitting substrate is reflected by the first light transmission element and leaves the first light-transmitting substrate. A second color beam incident on the first light-transmitting substrate passes through the first light transmission element, is reflected by the second light transmission element, then passes through the first light transmission element, and leaves the first light-transmitting substrate. Paths of the first color beam and the second color beam incident on or leaving the first light-transmitting substrate coincide.

摘要： A light source module used in a projection device comprises a plurality of laser emitting elements and a light adjusting device. The laser emitting elements are configured to emit excitation beams. Each excitation beam is received by an optical system of the projection device to emit sub-beams. The light adjusting device comprises a plurality of light adjusting elements. The excitation beams penetrate through the light adjusting device and are output as output beams to be converted into illumination beams by the optical system. The light adjusting elements are disposed corresponding to at least some of the laser emitting elements with reference to the sub-beam light intensity distributions, so that the illumination beam light intensity distributions conform to a preset light intensity distribution. Furthermore, a projection device is provided and comprises at least one light source module, an optical system, at least one light valve and a projection lens.

摘要： A projector includes a light source module, an optical engine, a light valve and a projecting lens. The light source module includes light sources, optical fibers and a light integration rod. Each of the light sources provides an illumination sub-beam. Each of the illumination sub-beams transmits to the light integration rod through the corresponding optical fiber, and passes through the light integration rod and emits out to form a first illumination beam. The optical engine includes a phosphor wheel located at a transmission path of the first illumination beam and converting the first illumination beam into a second illumination beam. The light valve is located at a transmission path of the second illumination beam and converts the second illumination beam into an image beam. The projecting lens is located at a transmission path of the image beam and projects the image beam out of the projector.

摘要： An illumination system includes first laser light sources, second laser light sources, an optical module, and a light homogenizing element. The first and second laser light sources respectively provide first and second beams. A light spot area formed when the second beams are emitted is different from that formed when the first beams are emitted. The optical module converts the first beams into spot-expanding beams which form a light spot area different from that of the first beams. The light homogenizing element includes a light incident face disposed on transmission paths of the second beams and the spot-expanding beams. A difference between light spot areas formed by the second beams and the spot-expanding beams on the light incident face is less than a difference between light spot areas formed when the second beams and the first beams are emitted. A projection apparatus having the illumination system is further disclosed.
