| Title: |
Foldable Light Diffusion Box with Frame Assembly |
| Abstract: |
A lighting project or device has a housing having multiple adjacent sides
and a front, the housing being enclosed at least between par lamp and the
diffusion element. Multiple par lights are mounted to a frame and
positioned to send light out the front of the device. The box also has a
diffusion element (frame) disposed proximate its front end, and even may
have multiple elements preferably spaced apart. The element or elements
receive the light from the par lighting instruments and diffuse it to
provide a soft projected light from the device. 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 frame
also supports the housing. The frame may be rectangular. The device may
also have a soft shell, may hang overhead, on a stand or by a rotatable
yoke, and may have lights fixed therein. The device may also have a rear
cover.
