1. A luminaire comprising:
a cylindrical base element comprising a base end and an opposing first interface end, wherein the base end is substantially parallel to a base plane, and wherein the first interface end is substantially parallel to a cut plane inclined at an oblique cut angle relative to the base plane; a first rotary joint coupled to the cylindrical base element, the first rotary joint configured to enable the cylindrical base element to rotate about a base rotation axis, wherein the base rotation axis is normal to the base plane; a cylindrical illuminator element comprising a second interface end and an opposing emission end, wherein the second interface end is substantially parallel to the cut plane; and a second rotary joint coupled to the cylindrical illuminator element and the cylindrical base element, the second rotary joint configured to enable the cylindrical illuminator element to pivot about a pivot rotation axis, wherein the pivot rotation axis is normal to the cut plane, wherein the cylindrical illuminator element further comprises a light source configured to generate a light beam for transmission through the emission end, and wherein a direction for the light beam is determined according to a rotational position of the cylindrical base element about the base rotation axis and a rotational position of the cylindrical illuminator element about the pivot rotation axis. |
