A light source module includes a laser light source, and an optical lens facing the laser light source. The optical lens includes a first light reflecting face, a second light reflecting face facing the first light reflecting face, a light incident face connecting the first light reflecting face and the second light reflecting face, and a light emitting face opposite to the light incident face. Light emitted from the laser light source is firstly reflected to the second reflecting face by the first reflecting face, then reflected to the light incident face by the second reflecting face, and then entered into the optical lens from the light incident face, and transmitted in the optical lens, finally exited from the light emitting face. |
