摘要： A laser mixing module includes first, second, and third laser sets and a condensing lens. The first laser set includes first and second laser sources and a first polarization beam splitter reflecting a polarization light of the first laser source and allowing a polarization light of the second laser source to pass for forming a first laser beam. The second laser set includes third and fourth laser sources and a second polarization beam splitter reflecting a polarization light of the third laser source and allowing a polarization light of the fourth laser source to pass therethrough for forming a second laser beam. The third laser set includes a fifth laser source and first and second dichroic mirrors respectively reflecting the first and second laser beams and allowing a light of the fifth laser source to pass for forming a third laser beam. The condensing lens condenses the third laser beam.

摘要： A laser projector includes a laser source, a first dichroic mirror, a wavelength conversion module, a second dichroic mirror, a first, a second and a third light valves and a beam combiner. The laser source is for providing a blue beam including a first portion and a second portion. The first dichroic mirror is for receiving and allowing the blue beam to penetrate. The wavelength conversion module is for receiving the first portion and emitting a yellow beam to the first dichroic mirror. The second dichroic mirror is for receiving and separating the yellow beam reflected by the first dichroic mirror into a green and a red beam. The first, second and third light valve are for receiving and modulating respectively the second portion of the blue beam, the green beam and the red beam. The beam combiner is for the beams to form a multi-color image.

摘要： A projector includes a first light source, a second light source, a collimating lens, a wavelength conversion module and a dichroic mirror. The first light source and the second light source respectively emit a first illumination beam and a second illumination beam. The collimating lens includes a first part and a second part and configured to receive and transmit the first illumination beam. The wavelength conversion module receives the first illumination beam from the first part, and generates an excitation beam transmitted toward the first part and the second part. The dichroic mirror corresponds to the first part, and configured to reflect the first illumination beam and the second illumination beam respectively to different directions for projecting the first illumination beam onto the first part and to be passed by the excitation beam.

摘要： A light source module includes first to third light sources respectively providing first, second and third lights, first and second wavelength conversion layers, first and second auxiliary light sources respectively providing first and second auxiliary lights, and a dichroic member. The first wavelength conversion layer is excited by the first light and the first auxiliary light from different sides to generate a first conversion light. The second wavelength conversion layer is excited by the second light and the second auxiliary light from different sides to generate a second conversion light. The dichroic member allows the first and second auxiliary lights to transmit therethrough and reflects the first and second conversion lights. The third light transmits through the dichroic member. The first and second conversion lights and the third light are different in wavelength ranges and combined to form an illumination light.
