Laser projection apparatus

A laser projection apparatus, comprising:

• an apparatus housing;
• a laser source system disposed in the apparatus housing, including:
• a first laser assembly disposed on a first plane and configured to emit a first laser beam,
• a second laser assembly disposed on a second plane perpendicular to the first plane and configured to emit a second laser beam,
• a third laser assembly arranged side by side with the second laser assembly on the second plane, wherein the second laser assembly is more proximate to the first laser assembly than the third laser assembly, and the third laser assembly is configured to emit a third laser beam,
• a first laser combining lens disposed at a position opposite to the third laser assembly, and configured to reflect the third laser beam,
• a second laser combining lens disposed at a junction of the second laser beam and the third laser beam, and configured to transmit the second laser beam and reflect the third laser beam, and
• a third laser combining lens disposed at a junction of the first laser beam and both the second laser beam and the third laser beam propagating from the second laser combining lens, the third laser combining lens configured to transmit the first laser beam and reflect the second laser beam and the third laser beam, so that the first laser beam, the second laser beam and the third laser beam are directed toward a laser outlet of the laser source system;
• an optical illumination system disposed in the apparatus housing and configured to modulate laser beams emitted from the laser source system to generate a modulated beam;
• and
• a lens system disposed in the apparatus housing and configured to project the modulated beam onto a projection screen.
