Abstract
A light projector module comprises a support, a light source for emitting in a beam path a light beam, a micro-electro-mechanical-system (MEMS) mirror for deflecting the emitted light beam, a waveguide having an in-coupling area for receiving the deflected light beam and an out-coupling area for projecting the deflected light beam with enlarged cross section, and a static mirror in the beam path from the light source to the MEMS mirror to fold the beam path about an angle of folding. The static mirror lies beside the first side of the waveguide.
