Abstract:
A dual color laser light source and a laser projector. The laser light source comprises a light composition member (24) used to shine a first blue laser light onto a phosphor wheel (23), and to reflect green fluorescent light, produced when the first blue laser light irradiates a green fluorescent light region (Y), to a light collecting member (25). The light composition member (24) is further used to shine a second blue laser light onto the light collecting member (25), and to reflect a red laser, emitted by a red laser emitter (102) and shone by a shining region, to the light collecting member (25). The optical circuit system is simple and has a low volume.
