Embodiments of the present disclosure describe a laser projection apparatus. The laser projection apparatus includes a laser source system, an optical engine, a lens system that are sequentially connected in a laser beam propagation direction, a plurality of circuit boards, a first heat dissipation system, and a second heat dissipation system. The first heat dissipation system is configured to dissipate heat of a first laser assembly in the laser source system, the optical engine, and the plurality of circuit boards, and to make airflow sequentially flow through the above components to form a first heat dissipation path. The second heat dissipation system is configured to dissipate heat of a second laser assembly in the laser source system, the lens system, and the plurality of circuit boards, and to make airflow sequentially flow through the above components to form a second heat dissipation path.
