The typical design of a Fresnel lensed instrument consists of placing the lamp (light source) at (or very near to) the focal point of the lens to achieve a "SPOT". This being the furthest point from the lens, typically the fixture housing is designed around this maximum distance. Our design allows us to shrink such fixture by at least one third in depth. We basically devised a variable geometry unit in which the overall housing has been split in two collapsible parts.
The Drop-in Fresnel lenses are removable allowing quick access to the popular "Open Eye" (no lens) sharp shadow projection mode. Two Fresnels are offered: a Soft (74 x 25 degrees beam patterns) and a Spot (44 x 6 degrees). Precise lamp and reflector positioning insure a clean light and shadow quality. Double shadowing has been eliminated in either mode.
The Barndoor for such a wide beam system had to be completely re-thought and the proposed version behaves more like miniature flags capable of reaching far past the lens in front or back of it. The front end is outfitted with special plugs made to receive Chimera poles.
The Back Cover of the unit supports: all the ignition electronics, the lamp, its socket and its reflector, reducing maintenance intervention as well as down time. It can also be replaced by tungsten back converting the unit into 600W, 3200Kelvin. |
