Abstract:

An improved outdoor lighting shield is provided for more efficiently illuminating large areas, such as roadways and parking lots. The shield is comprised of a standard lighting base and bulb, a translucent diffusing cylinder wrapped around the bulb, a reflective strip mounted around the diffusing cylinder, a highly-reflective truncated cone, and a non-reflective inverted cone mounted on top of the truncated cone. The diffusing cylinder softens light to reduce glare in the areas closest to the streetlight. The reflective strip reflects excess light onto the truncated cone, which casts a powerful ring of undiffused light to areas further from the streetlight. Any light that would normally be thrown into the atmosphere, causing light pollution, is caught by the inverted cone, which casts diffused light directly below the streetlight.
