ABSTRACT:
A lighting fixture utilizing a housing surrounding a fluorescent light source. The housing has an aperture defining an edge portion for determining the cutoff angle of light emanating from the source. A first upper reflector is formed on the inner surface of the housing, directing light from the source at angles ranging between the cutoff angle and angles less than the cutoff angle. The second reflector, located adjacent first reflector in the housing between the housing aperture and the first reflector, directs light from the source ranging between a selected angle, which is less than the cutoff angle, and at angles less than the selected angle. The result is a lighting fixture which possesses an optical delay in the activation in the second reflector as one approaches the optical axis from a peripheral position.
