## Abstract

A lighting fixture includes a light source module having a base with a surface having first and second lateral edges, and a plurality of light sources disposed on the surface of the base. A cover disposed over the light source module includes a light-transmissive main surface terminating at third and fourth lateral edges. A first light-transmissive side surface extends from the third lateral edge towards the first lateral edge, and a second light-transmissive side surface extends from the fourth lateral edge towards the second lateral edge. The first lateral edge is laterally offset by a first distance from a first orthogonal reference plane with respect to the third lateral edge, and the second lateral edge is laterally offset by a second distance from a second orthogonal reference plane with respect to the fourth lateral edge.
