| Title: |
Electrically Adjustable Optical Diffusion for Luminaires |
| Abstract: |
Diffusing light illuminating a light target or subject of a film or video
production including placing a diffusion panel between a light source and
a light target, energizing said light source so as to direct light
therefrom through the diffusion panel, and electrically adjusting the
transparency of the diffusion panel by changing an electric potential
applied to electrodes of the diffusion panel. The electrically adjustable
diffusion panel eliminates the need for manually changing diffusion
papers or other filters and provides a continuous range of selectable
levels of transparency/diffusion.
