ABSTRACT:
A luminaire with modular louver shields is disclosed that is particularly suited for use in the interior of parking garage structures. The luminaire is constructed so as to address the three-dimensional lighting requirements in parking garages, providing adequate illumination while reducing the glare in drivers and pedestrians eyes and reducing the amount of light that spills out of the structure. This is accomplished by using a lens that disperses light in the appropriate manner and removable louver assemblies that block or diffuse light rays that would otherwise shine in drivers and pedestrians eyes or spill out into the adjacent neighborhood. The lens and modular louver assemblies can be utilized in a number of configurations depending on the layout of the structure and the objective being addressed (eg: glare control, light spill). Once the luminaires are installed, the louvers can be rearranged to accommodate changing lighting requirements.
