Abstract: A projection device, including a light source module and a color wheel, is provided. The light source module includes a plurality of solid-state lighting sources driven by a DC drive power to sequentially provide a first light generated by a first number of light sources, a second light generated by a second number of light sources and a third light generated by a third number of light sources within a response cycle, wherein the number of light sources to be turn on is less than or equivalent to a total number of solid-state lighting sources. The color wheel has a first block, a second block and a third block, respectively corresponding to the first to third lights, so that the projection device sequentially outputs a first color light with a first brightness, a second color light with a second brightness and a third color light with a third brightness.

Abstract: A multicolor light mixing module includes a first laser set, a light-mixing unit, a light-homogenizing member and a condensing lens. The first laser set includes a plurality of first lighting units and at least one second lighting unit arranged symmetrically relative to a first symmetrical axis. The light-mixing unit is obliquely disposed on a first light-mixing axis and is opposite to the first lighting unit and the second lighting unit for reflecting a first color light of the first lighting unit and a second color light of the second lighting unit to cooperatively form a first laser beam along the first light-mixing axis. The light-homogenizing member is disposed on the first light-mixing axis for homogenizing the first laser beam. The condensing lens is disposed on the first light-mixing axis and located between the light-homogenizing member and the light-mixing unit for condensing the first laser beam.

Abstract: A multicolor light mixing module includes a light-dividing unit, a light-homogenizing member, a first laser set including first and second lighting units in a sequential arrangement, a light-mixing unit obliquely opposite to the light-dividing unit for guiding a first color light of the first lighting unit and a second color light of the second lighting unit along first and second light-mixing axes to form first and second laser beams, and a condensing lens. The light-dividing unit is obliquely opposite to the first laser set to allow partial transmission and partial reflection of the first and second color lights, for guiding the first and second color lights along first and second light-dividing axes. The light-homogenizing member is disposed on the first and second light-mixing axes for homogenizing the first and second laser beams. The condensing lens between the light-homogenizing member and the light-mixing unit condenses the first and second laser beams.

Abstract: A light source system includes a first light emitter configured to emit a first light with a first color band in a first time interval of a time period, a second light emitter configured to emit a second light with a second color band in a second time interval of the time period rather than in the rest of the time period other than the second time interval, and a light guide disposed downstream from the first light emitter and the second light emitter. The first time interval and the second time interval overlap in an overlapping time interval. The first light emitter and the second light emitter synchronously emit the first light and the second light in the overlapping time interval to form a combined light beam in the light guide. The light with the second color band is dominant of the combined light beam.

Abstract: A laser projector includes a laser light source, a first dichroic mirror, a second dichroic mirror, three light valves and a beam combining module. The laser light source is used to generate a composite polarized beam. The first dichroic mirror is used to receive the composite polarized beam, and separate the composite polarized beam into a first color beam and a relay beam. The second dichroic mirror is used to receive the relay beam, and separate the relay beam into a second color beam and a third color beam. The three light valves are used to modulate the three color beams into three light beams. The beam combining module is used to combine the three light beams to form a multi-color image.

Abstract: An alignment module includes a polarized dichroic mirror, a dichroic mirror, a phase retarding component and several light sources. The polarized dichroic mirror reflects specific beams and is passed by other beams. The dichroic mirror is disposed on a side of the polarized dichroic mirror, and reflects specific beams and is passed by other beams. The phase retarding component is disposed by the dichroic mirror and adapted to transform a polarization state of a beam passing the phase retarding component. The light sources are respectively disposed on different sides of the polarized dichroic mirror, and respectively output a beam toward the polarized dichroic mirror. The polarized dichroic mirror can transmit some beams toward a light pipe, and further transmit other beams toward the dichroic mirror and the phase retarding component for transforming the polarization state and then transmit the transformed beams toward the light pipe.
