Abstract
A refractive lens member for use with a luminaire is constructed to minimize high angle glare. The grid comprises a plurality of lenses which are interconnected by a rib structure to form a pattern of lenses in a network grid, with the lenses all lying substantially in the same plane. Each individual lens has a flat circular light incident surface and each lens has a substantially convex, spherical section light emergent surface. The rib structure is made of the same material as the lenses and may be integrally formed with the lenses to form the network grid. The rib structure is constructed to cooperate with the lenses to which prevent light at angles outside a pre-established range arrives on the light incident side surfaces from exiting from the light emergent surfaces of said lenses.
