Energy-saving fluorescent lamp wick column

Abstract

The invention relates to an energy-saving fluorescent lamp wick column which comprises a horn pipe, an exhaust pipe, a guiding wire, an electrode and an exhaust hole, wherein one end of the exhaust pipe is sleeved in the horn pipe, the electrode is connected with the guiding wire, the exhaust hole is arranged on the exhaust pipe, a front upper boss and a rear lower boss are correspondingly arranged in a staggered mode on the inner wall of the exhaust pipe sleeved between the horn pipe and the exhaust hole, and an isolated ball is clamped in the exhaust pipe between the front upper boss and the rear lower boss. Because the isolated ball is clamped in the exhaust pipe between the front upper boss and the rear lower boss, stationary mercury positioned in the exhaust pipe is blocked at a communicating pipe provided with the isolated ball, mercury vapor can enter a lamp pipe at the time, and solid mercury can not enter the lamp pipe. The invention has simple structure, long service life and good energy-saving effect.

Description

technical field [0001] The invention relates to an energy-saving fluorescent lamp core column. Background technique [0002] The core column of the energy-saving fluorescent lamp currently used is one of its important parts. During use, it is required that the fixed mercury cannot enter the lamp tube from the vent hole. However, most of the existing technologies use the method of shrinking the exhaust pipe located in the horn tube into the tube. The method of reducing the aperture is used to prevent solid mercury from entering the lamp tube. During use, sometimes solid mercury rolls out of the stem vent hole into the lamp tube, which affects the service life of the energy-saving lamp. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an energy-saving fluorescent lamp core column with simple structure, long service life and good energy-saving effect. [0004] The present invention adopts following technical scheme:...
