Abstract
An arena light reflecting assembly includes an asymmetric parabolic shaped reflector having an exit aperture. The reflector surrounds a horizontally extending high intensity light source and has a focal axis that lies along an axis of an arc tube of the light source so that the reflector acts as a collimator redirecting light from the light source into essentially parallel rays from the exit aperture. A pan circumscribes the exit aperture and a louver assembly is disposed within the exit aperture behind a front surface of the pan.
