Title (EN) LASER PROJECTION DEVICE AND LASER PROJECTION SYSTEM
(FR) DISPOSITIF DE PROJECTION LASER ET SYSTÈME DE PROJECTION LASER
Abstract:
(EN) A laser projection device and a laser projection system. The laser projection device comprises a light source scanner (1) and a MEMS scanning mirror (2), the light source scanner (1) comprising micro laser diodes (11); and the micro laser diodes (11) are used to provide laser beams needed for image projection, and the laser beams are projected to the MEMS scanning mirror (2), and then reflected by the MEMS scanning mirror (2) to a predetermined area (3) to form a projection image. By providing the micro laser diodes (11) in the laser projection device and initiatively emitting laser by exciting the micro laser diodes (11), the laser projection device does not need an external laser source and facilitates the reduction of the size of the laser projection device, as compared with the prior art.
(FR) L'invention concerne un dispositif de projection laser et un système de projection laser. Le dispositif de projection laser comprend un dispositif de balayage de source de lumière (1) et un miroir de balayage MEMS (2), le dispositif de balayage de source de lumière (1) comprenant des microdiodes laser (11) ; et les microdiodes laser (11) sont utilisés pour fournir des faisceaux laser nécessaires à la projection d'images, et les faisceaux laser sont projetés sur le miroir de balayage MEMS (2), puis réfléchis par le miroir de balayage MEMS (2) vers une zone prédéterminée (3) pour former une image de projection. En fournissant les microdiodes laser (11) dans le dispositif de projection laser et en émettant initialement un laser au moyen de l'excitation des microdiodes laser (11), le dispositif de projection laser ne nécessite pas de source laser externe et permet la réduction de la taille du dispositif de projection laser, en comparaison avec l'état de la technique.
