We claim the ornamental design for a lighting apparatus, as shown and described.
FIG. 1 is a top perspective view of a lighting apparatus of the present invention;
FIG. 2 is a front view thereof, the rear view being a mirror image thereof;
FIG. 3 is a left side view thereof, the right side view being a mirror image thereof;
FIG. 4 is a top view thereof; and,
FIG. 5 is a bottom view thereof.
Hemispherical projections on a substrate are transparent and thus light comes through. The two rectangles are electrodes.
