摘要： 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.

摘要： 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.

摘要： A projector includes a light source module, a collimating lens, a dichroic mirror and a wavelength conversion module. The light source module is configured to provide an illumination beam. The collimating lens is configured to collimate the illumination beam. The collimating lens includes a first part and a second part, and an axle positioned between the first part and the second part. The wavelength conversion module is configured to receive the illumination beam from the first part, and further to generate an excitation beam transmitted toward the first part and the second part. The dichroic mirror is disposed on a position corresponding to the first part. The dichroic mirror is configured to reflect the illumination beam toward the first part and be passed by the excitation beam, or further configured to be passed by the illumination beam and reflect the illumination beam.

摘要： A multicolor light mixing module includes a collimator lens disposed on a light-entrance axis and having first and second lens portions, a laser source set including first and second lighting units arranged sequentially for emitting first and second color lights respectively, a reflective unit, a reflective diffusing member and a lens array disposed corresponding to at least one of the first and second lens portions for mixing the first and second color lights. The reflective unit is obliquely disposed on the light-entrance axis and opposite to the first and second lighting units for reflecting the first and second color lights to the first lens portion along the light-entrance axis. The reflective diffusing member is disposed at a side of the collimator lens to homogenize the first and second laser lights and reflect the first and second color lights to the second lens portion along a first light-exit axis.

摘要： 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.

摘要： 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.
