1. A total internal reflection (TIR) lens comprising:
a refractive member having a body protruding in a first direction with respect to an electromagnetic source, the refractive member configured to receive electromagnetic radiation from the electromagnetic source and refract the electromagnetic radiation, the refractive member comprising:
a plurality of bottom longitudinal edges and a plurality of bottom lateral edges, wherein each bottom lateral edge forms a corner with at least one bottom longitudinal edge that creates an obtuse angle between the bottom lateral edge and bottom longitudinal edge forming the corner, wherein there are at least six total edges of the plurality of bottom longitudinal edges and the plurality of bottom lateral edges, and
a collimator arranged about the refractive member, the collimator comprising:
an inner surface configured to receive at least a portion of the refracted electromagnetic radiation from the refractive member and refract the electromagnetic radiation through an exit plane of the lens,
a first top longitudinal edge,
a first top lateral edge, and
a first top corner formed between the first top longitudinal edge and the first top lateral edge.
