METHOD AND APPARATUS FOR BIDIRECTIONAL CONTROL OF THE COLOR AND DIFFUSION OF A LIGHT BEAM
First Claim
1. A light fixture, comprising:
- a light source;
a first flexible material coupled to a first scrolling mechanism, where the first scrolling mechanism is operable to move the first flexible material in a first direction and to position a selected portion of the first flexible material in a first part of a beam of light from the light source;
a second flexible material coupled to a second scrolling mechanism, wherein the second scrolling mechanism is operable to move the second flexible material in a second direction and to position a selected portion of the second flexible material in a second part of the beam of light; and
a device coupled to the first scrolling mechanism and the second scrolling mechanism, wherein the device is operableto move the first scrolling mechanism in a third direction that is different from the first direction and to position the first flexible material such that a third part of the beam of light does not pass through the first flexible material, andto move the second scrolling mechanism in a fourth direction that is different from the second direction and to position the second flexible material such that a fourth part of the beam of light does not pass through the second flexible material.

Abstract
A light fixture includes first and second flexible materials coupled to first and second scrolling mechanisms that move the material in first and second directions to position a selected portion of the first and second flexible materials in first and second parts of a light beam from the fixture. A device coupled to the first and second mechanisms may move the first and second mechanisms in third and fourth directions so that third and fourth parts of the light beam do not pass through the first and second flexible materials. The third and fourth directions are different than the first and second directions. Different areas of the first and second flexible materials may produce different colors. The light fixture may also include a third scrolling mechanism coupled to a flexible diffusion material, to diffuse at least a part of the light beam by a predetermined amount.

8. For use in a light fixture, a method of controlling characteristics of a beam of light, comprising:
-
moving a first flexible material with a first scrolling mechanism in a first direction to position a selected portion of the first flexible material in a first part of a beam of light; moving a second flexible material with a second scrolling mechanism in a second direction to position a selected portion of the second flexible material in a second part of the beam of light; moving the first scrolling mechanism in a third direction that is different from the first direction to position the first flexible material such that a third part of the beam of light does not pass through the first flexible material; and moving the second scrolling mechanism in a fourth direction that is different from the second direction to position the second flexible material such that a fourth part of the beam of light does not pass through the second flexible material. - View Dependent Claims (9, 10, 11, 12, 13)
