Abstract
The utility model discloses an external electrode fluorescent tube with stem has one end to fuse in two ends of external electrode fluorescent tube at least and has the stem. The inner wall of the fluorescent tube with the external electrode is coated with fluorescent powder; the lamp tube is filled with a small amount of Hg, Ar, Ne and other inert gases; the ends of the lamp tube are coated with a low resistivity conductive material. The utility model discloses the end of external electrode fluorescent tube with stem adopts the form of stem to seal, and processing is convenient, easy operation.
Description
Technical field
The utility model relates to a kind of external electrode fluorescence lamp pipe.
Background technology
External electrode fluorescence lamp pipe EEFL (External Electrode Fluorescent Lamp), it is a kind of new light source product that develops in the world in recent years, this fluorescent tube is different with general fluorescent lamp, mainly be outerly to put electromagnetic field that electrode produces to form in the fluorescent tube plasma luminescence body luminous, have therefore that power consumption is low, advantages such as lamp tube service life length, high brightness, temperature are low, easy installation.
But the external electrode fluorescence lamp pipe generally is directly glass tube to be heated after-drawing, bleed and seal in the prior art, operation inconvenience, and percent defective is higher when sealing.
Summary of the invention
The external electrode fluorescence lamp pipe that the utility model provides a kind of sealing operation to have the stem stem structure easily.
A kind of external electrode fluorescence lamp pipe that has stem stem has at least end fusion that stem stem is arranged in two terminations of external electrode fluorescence lamp pipe.
Described external electrode fluorescence lamp inside pipe wall scribbles fluorescent material; Be filled with inert gases such as a spot of Hg and Ar, Ne in the fluorescent tube; Lamp tube ends scribbles the electric conducting material of low-resistivity.
Stem stem is that the conventional fluorescent lamps pipe adds man-hour, seals the parts of employing, its shape, is configured in the prior aries such as Chinese utility model patent 02234614.7 report is all arranged.
Described external electrode fluorescence lamp pipe can be straight pipe type, U-shaped, spirality etc., and caliber is at 6.0～12.0mm.
Because the inside of stem stem fusion oviduct of stem stem behind the termination of external electrode fluorescence lamp pipe is exposed outside, so the inside of stem stem oviduct also scribbles the electric conducting material of low-resistivity.Before the inside of lamp tube ends and stem stem oviduct was coated with the electric conducting material of low-resistivity, coating part carries out frosted to be handled.
The utility model has the termination of the external electrode fluorescence lamp pipe of stem stem and adopts the form of stem stem to seal, and is easy to process, simple to operate.
Description of drawings
Fig. 1 has the external electrode fluorescence lamp tubular construction schematic diagram of stem stem for the utility model, and wherein fluorescent tube is a straight pipe type;
Fig. 2 has the external electrode fluorescence lamp tubular construction schematic diagram of stem stem for the utility model, and wherein fluorescent tube is a U-shaped;
Fig. 3 has the external electrode fluorescence lamp tubular construction schematic diagram of stem stem for the utility model, and wherein fluorescent tube is a spirality;
Fig. 4 has the structural representation before the stem stem incomplete fusion in the external electrode fluorescence lamp pipe of stem stem for the utility model;
Fig. 5 has the partial cutaway schematic of stem stem fusion behind fluorescent tube one end in the external electrode fluorescence lamp pipe of stem stem for the utility model.
Embodiment
The utility model has the external electrode fluorescence lamp pipe of stem stem, has at least end fusion that stem stem 2 is arranged in two terminations of external electrode fluorescence lamp pipe.Fluorescent tube 1 inwall of external electrode fluorescence lamp pipe scribbles fluorescent material; Be filled with a spot of Hg and inert gases such as Ar, Ne in the fluorescent tube 1; Fluorescent tube 1 two ends scribble the electric conducting material 3 of low-resistivity.
