Abstract
A lens assembly includes a total internal reflection 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 a 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. The holder also has three or more support members extending from the exterior surface toward the first end. The support members are adapted for centering the optical body member with respect to the light source and maintaining the light source in the specified position in relation to the optical body member.
