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.

Abstract: It's about a new kind of fluorescent springlamp, which includes lamp base (1), lower part of the plastic housing (2), cover for the plastic housing (3), spiral lamp tube (4), the PCB that placed inside the plastic housing (5) and some other components. Among them, the legs of the tube with filaments in them are straight. The characteristic of this springlamp is there are two notches on the PCB, and two holes on the upper cover of the housing as well, so the straight part of the tube can be placed in the housing. Moreover, the length of the straight part of the tube can be longer than the distance between the PCB in the housing and the top of 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. The diameter of the housing can be less than the diameter of the spiral tube part of the lamp, making the lamp more adaptable to all kinds of lamp fixtures.
