I claim the ornamental design for a lighting fixture, as shown and described.
FIG. 1 is a perspective view of a lighting fixture. The frame has four-way, ninety degree overall rotational symmetry. The lamps and support arms have three-way, one hundred twenty degree overall rotational symmetry. The frame rings and base each have a circular horizontal cross-section.
FIG. 2 is a side elevational view of the lighting fixture of FIG. 1.
FIG. 3 is a top plan view of the lighting fixture of FIG. 1.
FIG. 4 is a perspective view of a lighting fixture. This fixture has four-way, ninety degree overall rotational symmetry. The frame rings and base each have a circular horizontal cross-section.
FIG. 5 is a side elevational view of the lighting fixture of FIG. 4; and,
FIG. 6 is a top plan view of the lighting fixture of FIG. 4.
The broken lines shown in the drawings are for illustrative purposes only and form no part of the claimed design.
