Compact fluorescent springlamp
View Patent ↗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.
1. A fluorescent springlamp, which includes a lamp base, a lower part ( 2 ) of a plastic housing, an upper cover ( 3 ) for the housing, a spiral lamp tube ( 4 ), and a PCB ( 5 ) placed inside the plastic housing, wherein legs ( 7 ) of the tube with filaments in them are straight, wherein there are two holes ( 8 ) on the upper cover ( 3 ) for the housing and two relative notches ( 6 ) on the PCB ( 5 ), and wherein the straight legs ( 7 ) of the tube are completely placed in the plastic housing.
2. The springlamp of claim 1 , wherein a length of the straight legs ( 7 ) of the tube is longer than a distance (H) between the PCB ( 5 ) in the housing and an upper surface ( 9 ) of the upper cover for the housing.
