Abstract
The present application discloses a dual-color laser light source and a laser projector. In the laser light source, a light combining component is used to transmit a first blue laser to a fluorescent wheel, and the first blue laser irradiates a green fluorescent region to generate green fluorescence to be reflected to a light collecting component; the light combining component is also used to transmit second blue laser to the light collecting component; the light combining component is also used to reflect a red laser which is emitted by a red laser transmitter and transmitted by the transmission region to the light collecting component. The light path system of the present application is simple and has a small volume.
