First Claim
Patent Images
1. An assembly for directional lighting, comprising:
- a housing;
a plurality of collimators within said housing; and
a transmissive cover which is removably mounted over said plurality of collimators, said cover comprising a plurality of micro lenses, all of which are co-planar and shaped to determine a desired outgoing beam angle, said cover proximate to said collimators without substantially extending into said collimators.

Abstract
A directional lighting fixture having a variable beam angle that is easily adjusted. One or more lighting sources are disposed within a fixture housing. A removable cover is disposed over the open end of the housing. The cover comprises a micro lens structure that defines the beam angle of the light that is emitted from the fixture. The removable cover, or in some configurations portions of the cover, can be easily replaced by the end user to achieve a desired beam angle.

29. A fixture assembly, comprising:
-
a housing defining an interior cavity and an open end, said housing comprising a base; a plurality of light emitting diodes (LEDs) on a mounting surface of said base in said cavity; a plurality of collimators in said cavity, each of said collimators configured to collimate light from at least one of said LEDs toward said open end of said housing; and a cover which is removably mounted on said open end of said housing and proximate to at least one collimator in said plurality of collimators without substantially extending into said at least one collimator, said cover comprising a plurality of micro lenses, all of which are co-planar and shaped to determine the beam angle of light exiting said open end of said housing. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
