Abstract
A total reflection lens includes a first end surface with a first diameter, and a second end surface parallel to the first end surface and with a second diameter. The second diameter is greater than the first diameter, and the two end surfaces are connected via a convexly curved lateral surface. A recess adjoining the first end surface and pointing in the direction of the second end surface is located between the first end surface and the second end surface. The recess has at least two boundary surface portions, pointing in the direction of the second end surface and separate from one another, for refracting light in the direction of the lateral surface.
