I claim the ornamental design for a lighting fixture, as shown and described.
FIG. 1 is a perspective view of the lighting fixture. Excluding the upper radial support bars for the shade, the fixture has six-way, sixty-degree rotational symmetry. The hanging support bar, arms and candles each have a circular cross-section.
FIG. 2 is a top plan view thereof, with the canopy removed for illustrative purposes;
FIG. 3 is a side elevation view thereof, with the support rod shown fragmentarily for ease of illustration only; and,
FIG. 4 is a fragmentary side elevation view showing a portion of the centerpiece and the upper and lower shade frames, one arm and candle, an upper radial support bar, and one shade element extending between the upper and lower shade frames.
The dashed lines on the drawing depict portions of the lighting fixture that form no part of the claimed design. The dot-dash lines in FIG. 4 represent the location on the fixture where the fragmentary view is cut.
