Abstract
An exemplary laser projection device includes a substrate, three laser chips mounted on the substrate, and a spectroscope arranged on laser beams paths of the laser chips. Each laser chip is a laser diode. The spectroscope includes a first group of splitters, and a second group of splitters spaced from the first group of splitters. Laser beams emitted from the laser chips are adjusted into the second group of splitters by the first group of splitters. And then, the laser beams adjusted into the second group of splitters are adjusted to be oriented toward the same direction and mixed together to obtain light of a predetermined color.
