  • Tubular electric lamp fixture
    Patent number: 4723199
    Abstract: A fixture for a plurality of tubular electric lamps comprises an elongated insulating angular frame having two perpendicular flanges joined together. Metal conductor strips carried on the back side of the flanges have integral lamp carrying tabs spaced along the length of the conductors that protrude through slots in the frame. Tabs are thus disposed along the entire length of the frame to support lamps in axial alignment. The flat conductors are secured to the back side of the flanges by crimping the portion of the tabs adjacent the front side of the flanges.
