Work/Description
Abstract/
Conceptualize and design an automated shutter module that integrates into Electronic Theatre Controls' Source Four Revolution theater light and allows for customizable, configurable spotlight shapes.
Challenge/
Create a robust, low-cost light shutter mechanism that must operate reliably at elevated temperatures, fit in a very small envelope and be capable of creating ANY 3- or 4-sided shape.
Solution/
DCI conceptualized a novel, innovative new mechanism for the shutter module. The inner workings of the shutter were reduced down to a stack of interlinked sheet metal irises which can be manipulated to create an infinite variety of shutter cuts. Eight computer-controlled stepper motors synchronize the motion of four shutter blades for unique and dynamic lighting effects.
Results/
The finished product uses only 7 unique sheet metal parts configured to achieve the shutter mechanism. It withstands temperatures in excess of 170°F without binding. The shutter can be programmed to form any 4-sided or 3-sided shape for unique spotlight patterns. Each shutter blade can rotate +/- 45 degrees — a first in the industry. Electronic Theatre Controls has filed for multiple patents on this novel design.
