COUPLING WITH INTEGRAL FLUID PENETRATION BARRIER

摘要

The present disclosure provides a support coupling which provides a frangible point for a lighting fixture, and which prevents water from accumulating at the frangible point and from penetrating an inner chamber of the lighting fixture where electronic components are disposed. In certain example embodiments, the coupling accomplishes this by providing an inner wall and an outer wall, in which the inner wall has a higher grade (i.e., is taller) than the outer wall. A space between the inner wall and the outer wall receives an extension column. Water running down the sides of the extension column is collected in the space and pours out of the coupling over the shorter outer wall before the water reaches the top of the inner wall.
