Linear aisle light optic for leds

A luminaire comprising:

• a substrate;
• a plurality of linearly aligned LEDs mounted on the substrate;
• and
• an optical element for uniformly dispersing light from the plurality of linearly aligned LEDs mounted on the substrate with a light emitting surface of the LED disposed between the substrate and the optical element, the optical element having a shaped body made of an optically transmissive polymeric material, the body having length, width and depth, wherein the length is greater than each of the width and the depth, and wherein the body has a substantially uniform transverse cross-sectional profile, the body including a longitudinally extending center portion and legs extending in the width direction away from opposite sides of the central portion and extending downwardly in the depth direction to facilitate mounting of the body on a substrate with a light emitting surface of an LED positioned in a recess defined between the substrate and the body, the center portion having a top surface and a bottom surface that together define a longitudinally extending lens portion capable of collecting light from an LED and refracting the light to produce a beam pattern.
