    Patent number: 4650265
    Abstract: An illuminating lamp assembly (20,20') for supporting fluorescent tubes in an exit sign (10) including a body (22) for supporting a pair fluorescent tubes (24) and an electrical connector (26) rotatable about a first axis for threadedly engaging an electrical socket (18). A support member (28,60) interconnects the body (22) and the electrical connector (26) for allowing the electrical connector (26) to rotate about the first axis independently of the body (22). The assembly (20,20') is characterized by the body (22) including an elongated central portion (52) and positioning flanges (54) extending in opposite directions from each end thereof defining an H-shaped structure for supporting the fluorescent tubes (24) in positions visible from both sides of the body (22). Accordingly, the assembly (20,20') can be used to illuminate two opposite faces of an exit sign (10).
