Description

A kind of hollow glass stick stem

Technical field

The utility model is related to LED lamp technical fields, more particularly, to a kind of hollow glass stick stem.

Background technology

The stem of fluorescent lamp, which is divided into, hollow column and non-porous stem, they are made of oviduct, exhaust pipe and seal wire, makees Be filament supports, conduction electric current and with fluorescent tube sealing-in, during lamp processed by they be vented, rinse and be filled with filler. China Patent Publication No. CN2927312 discloses a kind of improved core of mercury lamp, including the first seal wire and the second seal wire, and described two Seal wire has one end to be plugged in the loudspeaker of upper end opening, and an exhaust pipe is arranged in the loudspeaker, and wherein one end is led positioned at two Between silk plugs position, first seal wire is bent by several sections, and the second seal wire is bent by two sections, is had between any two big Cause bending part in 90 °.Two seal wires of existing lamppost, which are easy to happen, to be contacted with each other, to cause the damage of lamppost.

Invention content

The utility model is to provide a kind of sky that seal wire is isolated to overcome the problems, such as that prior art seal wire is exposed to contact Heart glass bar stem.

To achieve the goals above, the utility model uses following technical scheme：A kind of hollow glass stick stem, including glass The outer wall of glass loudspeaker, exhaust pipe, seal wire and hollow glass stick, the glass horn is equipped with venthole, the right side of the exhaust pipe End is inserted in the inside of exhaust pipe, and the left end of exhaust pipe extends to the outside of glass horn, the right side of venthole and exhaust pipe to the left End perforation, the hollow glass stick is located at glass horn central axis direction and is fixedly connected on the right end of glass horn, described to lead Silk includes the first seal wire and the second seal wire, and one end of first seal wire passes through glass horn from the left side of glass horn and is arranged It penetrates on the left of glass horn and is worn on the right side of glass horn in one end of the inside of hollow glass tube, second seal wire Go out.

For the utility model in the right end setting hollow glass tube of glass horn, hollow glass tube is sheathed on the outer of seal wire Portion avoids the first seal wire and the second seal wire and mutually touches and with a seal wire, extend fluorescent lamp service life.

Preferably, being equipped with solid mercury in the exhaust pipe.

Temperature raising can cause temperature to rise light decay, and solid mercury can solve the problems, such as temperature rise and caused by light decay, improve the effect that shines Rate.

Preferably, the right end of the exhaust pipe is equipped with the first filter, the solid mercury of the first filter blocking is moved to venthole.

First filter can stop that solid mercury is moved to venthole, prevent solid mercury from entering in fluorescent tube, destroy the fluorescence on inner wall Powder causes fluorescent powder to fall off.

Preferably, being equipped with the second filter in the exhaust pipe, the second filter is located at the left of the first filter, the solid mercury Between the first filter and the second filter.

Solid mercury is fixed using the second filter and the first filter makes the position of solid mercury close proximity to filament, adds after filament fever The volatilization of fast mercury admittedly, makes fluorescent lamp quickly shine after opening, the speed that shines is fast.

Preferably, the exhaust pipe is located at the central axis direction of glass horn.

Therefore, the utility model has the advantages that：（1）Avoid mutual touching between seal wire and with a seal wire, Extend fluorescent lamp service life；（2）Luminous efficiency is high；（3）The speed that shines is fast.
