| Title: |
Method and Apparatus For Bidirectional Control of the Color and Diffusion of a Light Beam |
| Abstract: |
A light fixture includes a flexible color filter material coupled to a
scrolling mechanism that moves the material in a first direction to
position a selected portion of the color filter material in a part of a
light beam from the fixture. A device coupled to the mechanism may move
the mechanism in a second direction so that another part of the light
beam passes unfiltered. Different areas of the color filter material
produce different colors. The device may move the mechanism in a
direction parallel to a plane of the color filter material. The device
may rotate the scrolling mechanism about an axis of rotation
substantially parallel to the plane of the color filter material. The
color filter material may include a dichroic filter. The light fixture
may also include a second scrolling mechanism coupled to flexible
diffusion material, such that at least a part of the light beam of the
light fixture may be diffused by a predetermined amount.
