Abstract
In an embodiment a reflector optical system includes 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.
Claims20
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.
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 each of the second reflective surfaces includes an inclination angle with respect to the longitudinal axis, and
- wherein an inclination angle decreases with increasing distance from the first reflector optics portion along the longitudinal axis.
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 second reflector optic portion is bound by an annular flange portion having an end face defining a plane perpendicular to the longitudinal axis,
- wherein the second reflector optic portion formed by the second reflective surfaces extends from a tip portion of a pin at least up to an intersection of the second reflector optic portion with the plane defined by the end face, and
- wherein a length of the second reflector optic portion is between about 4.0 mm and about 5.9 mm, inclusive.
