Abstract
A laser projection apparatus includes a laser source, a light modulating engine and a projection lens. The laser source includes a laser device, a combining component, a first lens and a phosphor wheel. The combining component includes a reflecting region and two transmitting regions. The reflecting region is configured to reflect a laser beam and a fluorescent beam incident on the reflecting region. The two transmitting regions are disposed on two sides of the reflecting region respectively, and the transmitting regions are configured to transmit a plurality of laser beams emitted by the laser device. The phosphor wheel includes a first region and a second region. The first region is configured to diffuse and reflect the laser beams incident on the first region. The second region is configured to be excited to emit a fluorescent beam due to irradiation of the laser beams incident on the second region.
