  • Patent number: 7619353
    Abstract: It's about a new kind of fluorescent springlamp, which includes lamp base (1), lower part of a housing (2), upper cover for the housing (3), spiral lamp tube (4), and a PCB that placed inside the housing (5). Among them, the legs of the tube with filaments in them are straight. There are two notches on the PCB, and two holes on the upper cover of the housing as well, so the straight legs of the tube can be placed in the housing. Moreover, the length of the straight legs of the tube can be longer than the distance between the PCB in the housing and the facing surface of the upper cover for the housing. This method can greatly reduce the overall height of the lamp and reduce the operating temperature in the housing, which increased the working efficiency of the lamp and prolonged the lamp life.
