Forward throw asymmetric optic design

A lighting unit configured to illuminate a surface having a proximal portion and a distal portion in relation to the lighting unit, the lighting unit comprising:

• a light source configured to emit a light beam;
• an optic positioned between the light source and the surface, the optic configured to modify the emitted light beam to comprise a largely uniform illumination distribution along the surface, and comprising an input surface facing the light source, the input surface comprising:
• (i) a convex lens portion configured to direct a portion of the emitted light beam at the distal portion of the surface, and (ii) a concave lens portion configured to direct a portion of the emitted light beam at the proximal portion of the surface;
• and
• a diffuser positioned between the optic and the surface,
• wherein the diffuser is placed over the optic and at least partially contoured around the optic.
