ABSTRACT:
A fixture for a plurality of tubular electric lamps comprises an elongated insulating angle bar-frame having two flat mutually perpendicular flanges joined by a flat central web at 45.degree. angle to the flanges. Flat metal conductor bars carried on the back side of the flanges have integrally upstanding lamp carrying tabs spaced along the entire length of the conductors protrudes through slots in the frame. Lamp carrying tabs are thus alternately disposed along the entire length of the frame which support the lamps in axial alignment. The flat conductors are secured to the back side of the flanges by means of self-adhesive bands. Improved structural strength is achieved by the frames having integral ribs or struts connecting the perpendicular flanges and the flat central web.
