Claim 7:
8. A method for assembling a laser module, wherein the method comprises steps as follows:
installing a transparent protective plate, a light diffusion plate, a lens holder, a lens, and a hold-down ring in an inner cavity of a lamp body in sequence, wherein a protruding annular ridge of the hold-down ring is engaged in an annular recess of the lamp body, such that the hold-down ring is fixedly arranged on the lamp body to assemble a lens module;
installing the lens module through an end of the height adjustment barrel in such a manner that a protruding annular portion of the lamp body is engaged in an annular groove of the height adjustment barrel, such that the lens module is fixedly arranged in the height adjustment barrel;
pressing a laser diode into a heat sink, and threading external threads of the heat sink into internal threads of the height adjustment barrel; and
adjusting a focal length between the laser diode and the lens by threads, to achieve optimized illumination effect.
