Abstract
A lighting apparatus includes a light source having a plurality of light-emitting-diodes and a lens assembly with a lens and a lens holder. The lens includes a body member having an outer surface shaped to provide total internal reflection and an interior open channel extending longitudinally through the body member. The body member has a first end region for accommodating the light source and a second end region that includes a plurality of refractive surface regions positioned around the open channel. The lens holder has a concave interior surface shaped to accommodate the optical body member of the lens and a convex exterior surface. The holder has multiple clips for securing the lens and three or more support members extending from the exterior surface toward the first end.
