I claim the ornamental design for a lighting fixture, as shown and described.
FIG. 1 is a perspective view of a lighting fixture. Excluding the lamp hanging hardware and the staggered lengths of the lamp cables, this fixture has mirror image symmetry, including one hundred eighty degree overall rotational symmetry, and mirror image symmetry along a first vertical imaginary plane and also mirror image symmetry along a second vertical imaginary plane, with the first and second vertical imaginary planes being orthogonal to each other. The lamp bases and glasses each have a circular horizontal cross-section.
FIG. 2 is a front view of the lighting fixture of FIG. 1, shown with the cables sectioned to allow for an enlarged view of the canopy and lamps, with the cable staggering altered, and with the lamps rotated to illustrate side views of the lamp hanging hardware; and,
FIG. 3 is a side view of the lighting fixture of FIG. 1, shown with the cables sectioned to allow for an enlarged view of the canopy and lamps, with the cable staggering eliminated, and with the lamps rotated to illustrate end views of the lamp hanging hardware.
The broken lines shown in the drawings depict portions of the lighting fixture that form no part of the claimed design.
