1. A reflector optical system comprising:
a reflector body having a rotational symmetry about a longitudinal axis and including a first reflector optic portion having a substantially concave shape; and
a second reflector optic portion extending along the longitudinal axis, the first reflector optic portion facing the second reflector optic portion,
wherein the first reflector optic portion includes a plurality of first reflective surfaces and the second reflector optic portion includes a plurality of second reflective surfaces in spaced light-receiving relation to the plurality of first reflective surfaces,
wherein the first reflective surfaces are conical or skirt shaped, and are arranged concentric about the longitudinal axis, and
wherein, in the first reflector optic portion, an inclination of the conical or skirt shaped first reflective surfaces, with respect to the longitudinal axis, increases with increasing distance from the longitudinal axis.
