ABSTRACT:
Lighting apparatus comprising a long span lightweight luminaire beam with a cross section that is substantially in the shape of an equilateral triangle and is formed in multiple sections secured together. One apex of the triangle is pointed downwardly. The side panels of the beam are used as mounting and reflecting surfaces for fluorescent lights or the like, while the ballast and wiring are mounted inside the beam to protect them from weather. The mounting hole for the ballast also serves as the access hole for assembly of the span, and the ballast may be inverted in its mounting for servicing. The beam is supported in an elevated, substantially horizontally extending position by one or more support posts. This apparatus is particularly advantageous for use in illuminating large outdoor areas such as tennis courts.
