The dashed lines on the drawings depict portions of the lighting fixture that form no part of the claimed design. The interior of the centerpiece of the lighting fixture as illustrated with section lines in FIG. 3 forms no part of the claimed design. The dot-dash lines in FIG. 3 represent the locations on the fixture where the fragmentary view is cut.
