FIG. 1 is a perspective view as viewed from above of the luminaire structure showing our design;
FIG. 2 is a perspective view as viewed from below thereof;
FIG. 3 is a front elevational view thereof, the rear elevation being a mirror image thereof and therefore omitted;
FIG. 4 is a right hand side elevational view thereof;
FIG. 5 is a left hand side elevational view thereof;
FIG. 6 is a bottom plan view thereof; and,

The broken line disclosure represents portions of the structure which form no part of the claimed design.
The luminaire structure is shown in various figures with symbolic break lines along its dimensions. The appearance of any portion of the article between the break lines does not form part of the design. A separation and a bracket are used to indicate that, for ease of illustration, the specific dimension of the article associated with the separation and bracket is not claimed and is to be broadly interpreted.
The luminaire structure is not limited to the scale shown here in.
