LASER PROJECTION DEVICE

摘要

A laser projection device includes a blue laser chip, a red laser chip and a green laser chip and a spectroscope arranged on light paths of laser beams emitted from the laser chips. The laser projection device further includes a substrate. The laser chips are mounted on the substrate. The laser beams emitted from the laser chips are converged by a lens to reach the spectroscope and then reflected by the spectroscope to mix together.
