Abstract

A lighting apparatus (10) includes a discharge arc lamp illumination source (12), an elliptical reflector (14) completely surrounding the illumination source for collecting and projecting light from the illumination source (12), a shutter for dimming the amount of light generated by the illumination source and emanating from the lighting apparatus. The shutter (18) is mechanically operable to define an optical passageway therethrough of variable cross sectional area. The shutter (18) includes a plurality of shutter blades mounted in a movable relationship relative to each other in response to user input. The shutter blades are movable to define the optical passageway of variable cross-sectional area to dim the amount to light from the illumination source passing therethrough over the range of from about 0 to 100 %.
