at least one light source having an optical axis; and
a lens body comprising:
a first body segment having a light-collection surface positioned adjacent the light source and extending to a first total-internal-reflection (TIR) surface;
a middle body segment extending from the first TIR surface to a second TIR surface;
a second body segment extending from the second TIR surface to a light emission surface defining an output optical axis,
