| Title: |
Beam Divergence and Shape Controlling Module for Projected Light |
| 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.
