ABSTRACT:
A lighting module that diffuses a light beam to modify the size and shape of the projected beam. The device includes a light source and a reflector to direct the light along an optic path. A primary lens element reduces the cross section of an effected light region as the light enters a diffusion assembly area in the optic path. Diffusion elements in the diffusion assembly are deployed in varying combinations and to varying degrees to produce the shape and/or size of light beam desired by the user. The action of the lens element allows the diffusion elements to be physically positioned in the optic path but to have no effect on the light until the diffusion elements are rotated so that diffusion element segments align with lens segments, and the diffusion element changes the light being projected from the lighting module.
