Abstract
A lens member for projecting light from an LED in a square pattern includes a body formed of a light transmissive material. The body includes a base portion and a bulbous-shaped, light-directing lens portion extending upwardly from the base portion. A recess extending upwardly from a lower surface of the base portion and into the bulbous-shaped, light-directing lens portion continuously tapers from the base to a flat, circular surface below a top surface of the bulbous-shaped, light-directing lens portion. The lens portion has a horizontal cross-sectional shape that is substantially square at elevations between the base and the top surface of the lens portion.
