The present invention provides an optical module of laser vehicle lamp, which includes a laser light source, a convex lens, a substrate, a reflector set, a plurality of support rods and a transmission member. The laser light source is capable of generating a laser beam. The convex lens is disposed on a propagation path of the laser beam generated by the light source so as to focus the laser beam. The substrate is disposed on the propagation path of the laser beam that has been focused by the lens, and the surface of the substrate is coated with yellow fluorescent powder. The reflector set is disposed on the propagation path of the laser beam reflected by the substrate. The support rods are disposed at the rear side of the reflector set for supporting the reflector set. The transmission member is disposed at the rear side of the reflector set, and is connected with the support rods. The transmission member drives the support rods to change the light reflection surface of the reflector set thereby changing the
