| Title: |
Conical Lens Array to Control Projected Light Beam Color, Divergence, and Shape |
| Abstract: |
A lighting module that modifies a light beam to affect the size and shape
and color characteristics of the projected beam includes a light source
and a reflector to direct the light along an optic path. The reflector is
formed so that light is directed along a light path that is not parallel
to a center line of the reflector. A primary lens element reduces the
cross section of an effected light region as the light enters a modifying
element area in the optic path. Light modifying elements are deployed in
varying combinations and to varying degrees to produce the shape, size,
and color of light beam desired by the user. The construction of the light
modifying elements allows the elements to be physically positioned in the
optic path but to have no effect on the light until the elements are
rotated so that light modifying element segments align with lens segments
of the primary optical element, and the light modifying element or
elements change the light being projected from the lighting module.
