Abstract

The laser supplementary lighting system for plant factories includes a laser emitter (1), a control circuit (2), a lens array (3), and first and a second reflector arrays (4,5); collimating lenses (13,17) are arranged in the laser emitter (1); the collimating lenses (13,17) collimate laser beams into collimated beams with a divergence angle of less than 0.3°; a bottom surface of the laser emitter (1) and emission ports on both sides in a horizontal direction are configured to emit long-wave laser beams and short-wave laser beams; three laser beams emitted from the laser emitter (1) are reflected by the first reflector array (4), reflected by the second reflector array (5), and homogenized by the lens array (3), respectively, and then projected downward to form rectangular light spots. The disclosure has the advantages of low energy consumption and low cost and realizes a high-uniformity multi-wavelength laser field with a large area at a short distance.
