| Title: |
Foldable Modular Light Diffusion Box |
| Abstract: |
A lighting box has a housing with an open front and open rear and a bar
such as a standard schedule 40 pipe or 11/2'' or 15/8'' pipe extending
horizontally across the housing. Multiple lights are mounted on the bar
and positioned to send light out the front of the box. The box also has a
diffusion element (frame) disposed proximate its front end, and even may
have multiple elements including having one element at an angle. The
element or elements receive the light from the lighting instruments and
diffuse it to provide a soft projected light from the box. In accordance
with one aspect of the invention, this light may be used to provide
diffused light as part of the key lighting for a stage or set, and may
provide such soft projected lighting from a front (downstage) of the
stage or set. The box may also have a soft shell, may hang overhead, on a
stand or by a rotatable yoke, and may have lights fixed therein. The box
may also have a rear cover.
