Specifiers and designers go to great lengths to pick the appropriate luminaire, lumen package, optical configuration and shielding for a given project. However, there will inevitably be unanticipated conditions that result in light trespass, which will require special solutions.
Common situations where shielding might be required include: blocking light output behind a luminaire, in front of a luminaire, or to the back & side of the luminaire; for example on a Cul-de sac street. To address these situations, lighting professionals use supplemental shields that can be provided at the factory, or can be installed in the field.
The shielding types illustrated below represent typical light distribution, however; there is at times some minimal light intensity above the angle shown. We provide IES files for all of our products, so that you may review details regarding shield performance and calculate actual illumination values.
