Description

FIG. 1 is a perspective view of the suspended ceiling T-bar with LED lighting;
FIG. 2 is an end cross-section view of the invention, the opposing end views being similar;
FIG. 3 is a top plan view of the invention;
FIG. 4 is a bottom plan view of the invention;
FIG. 5 is a bottom perspective view of the invention; and,
FIG. 6 is a front elevation view of the invention, the rear elevation view being a mirror image.
The dash-double dotted line shown in FIGS. 1 and 3-6 represents a symbolic break in the length of the article. The appearance of any portion of the article between the break lines forms no part of the claimed design. The broken lines in FIGS. 1 and 3-6 illustrate features that form no part of the claimed design.
