<p>The present utility model discloses a helical type fluorescent lamp tube, a connection type cold end (3) with an auxiliary amalgam (6) is placed on the top (2) of a lamp tube and is comprised of one glass tube. One end of the connection type cold end is connected to the lamp tube (1) , the auxiliary amalgam (6) is disposed on the top (2) inside the lamp tube through the connection type cold end (3) and is held by a conductor wire ( 8) , and the other end of the connection type cold end ( 3) is closed. The connection type cold end (3) independently-placed according to the present utility model (3) may be in an optimal temperature and position, so that the gas pressure of mercury in the lamp tube is adjusted to an optimal state. The placement of the auxiliary amalgam (6) effectively accelerates establishment of luminous flux in the lamp tube, thereby satisfies the application of the helical type fluorescent lamp in the lighting field with larger range.</p> |
