Light Diffusion Device

| Patent Number: |
7470044 |
| Title: |
Light Diffusion Device |
| Abstract: |
A light diffusion device permits a single light source to serve as both
direct lighting and fill lighting for a photographic, theatrical or
cinematographic subject. The light diffusion device partially reflects
light emitted from a light source away from the subject, using a
translucent panel. Additional translucent panels permit the reflected
light to escape from the light diffusion device into the surrounding
environment. The escaped light reflects from the surrounding environment,
thereby creating fill light around the subject, thus reducing or
eliminating undesirable shadowing.
