| Title: |
Compact Theatrical Light and Method |
| Abstract: |
A compact and efficient theatrical light that includes four mirrors, a gobo
apparatus a colorchanger/dowser/diffusion system, and a lens system. The
light beam is reflected four times, each time by 90 degrees. The second
reflection is perpendicular to the plane formed by the initial path of the
beam and the path after the first reflection. The gobo, the lens system
and the colorchanger/dowser/diffusion system are located between the
second and the third mirrors. This achieves a very compact, but fully
capable light which may be attached to and protected by a truss system
when in use and when in transport.
Also discussed is a simple color changer/dowser/diffusion system with color
glass panels mounted to tracks and moveable into and out of the optical
path by cables connected to each panel.
