Abstract
The utility model relates to a rolling sealed type spiral fluorescent lamp comprising a spiral lamp and a glass bead stem. The utility model is characterized in that the light tube adopts the rolling sealed type of glass bead stem to enclose. The straight foot of light tube covers the glass bead stem, and the end of the light tube and the glass bead stem are heated to melt by flames, and sealed by rolling mill. The utility model has the advantage that because the stem without horn does not occupy the space, the altitude of the straight foot of the light tube is reduced. The densification of the rolling seal is strong, reducing the gas leakage and inefficiency rate. Meanwhile, the stem can also be connected with the glass bead along the cathode at one side of the spiral to deflect into the spiral ring, further reducing the altitude of the straight foot of the light tube and compacting the spiral florescent lamp structure, therefore, it is more convenient in use.
Description
Technical field
The utility model relates to a kind of spiral fluorescent lamp, particularly a kind of rolling sealed type spiral fluorescent lamp.
Background technology
At present, spiral fluorescent lamp throws light on because of energy-conservation and good being widely used in of color rendering index, and the modeling structure to spiral fluorescent lamp has also proposed requirements at the higher level simultaneously, requires fluorescent tube moulding under high photoelectric characteristic prerequisite compact more.Existing fluorescent tube seals form and bulk has suitable relation, and the loudspeaker stem stem is adopted in sealing of general spiral fluorescent lamp, the fluorescent tube pin is placed on the loudspeaker stem stem, use the flame heat welding, the interior space of fluorescent tube only could be communicated, by blast pipe with ambient atmosphere for back road exhaust is prepared.This loudspeaker stem stem fusing type seals, and fluorescent tube pin portion highly is that pin portion takies than large space about 18mm, has influenced the compactedness of spiral fluorescent lamp.
Summary of the invention
The utility model seals pin portion and need take than large space in order to overcome existing loudspeaker stem stem fusing type, influence the compactedness of spiral fluorescent lamp, the utility model adopts bead stem stem rolling sealed type to seal, because stem stem does not have loudspeaker and takes up room, just shortened fluorescent tube pin height, made spiral fluorescent lamp compacter.The utility model design rolling sealed type spiral fluorescent lamp, comprise helical lamp, bead stem stem etc., it is characterized in that: fluorescent tube adopts bead stem stem rolling sealed type to seal, be about to the fluorescent tube pin and be placed on the bead stem stem, with lamp tube end and bead stem stem heating and melting, roll envelope with milling train with flame, the utility model has the advantages that: because stem stem does not have loudspeaker and takes up room, shortened fluorescent tube pin height, and roll the envelope compactness strong, can reduce the air leakage failure rate.Simultaneously, also stem stem can be connected bead and be deflected in the spiral coil, fluorescent tube pin height is further shortened to about 10mm, make the spiral fluorescent lamp more compact structure, use more convenient along the negative electrode of tube helix tube one side.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the utility model lamp tube end rolls envelope and bead stem stem structural representation.
Fig. 3 is the partial enlarged drawing that the utility model lamp tube end rolls envelope and negative electrode deflection.
Among the figure: 1 is helical lamp, and 1-1 is a helical lamp spiral coil portion, and 1-2 is a helical lamp pin portion, and 2 is tube chamber, and 3 is phosphor powder layer, and 4 is negative electrode, and 5 for connecting bead, and 6 for rolling envelope portion, and 7 is blast pipe, 8,8a is seal wire.
Embodiment
With reference to Fig. 1, in the tube chamber 2 of helical lamp 1, be filled with mercury and inert gas, scribble phosphor powder layer 3 on the tube wall, negative electrode 4 is deflected in the spiral coil 1-1 of fluorescent tube, and 5 is the bead that is connected of negative electrode 4 and seal wire 8,6 for rolling envelope portion, 7 is blast pipe, it is characterized in that: bead stem stem rolling sealed type structure shortens the height dimension of the helical lamp pin 1-2 of portion; Negative electrode 4 is deflected in the spiral coil 1-1, fluorescent tube pin height is further shortened, thereby make the spiral fluorescent lamp more compact structure, uses more convenient.
Among Fig. 2: the bead stem stem is by negative electrode 4, seal wire 8,8a and be connected bead 5 and form, the bead stem stem places the helical lamp pin 1-2 of portion, 6 for rolling envelope portion, blast pipe 7 is in order to vacuumize, and charge into inert gas to fluorescent tube, it is characterized in that: bead stem stem rolling sealed type structure shortens the height dimension of the helical lamp pin 1-2 of portion.
In the embodiment shown in fig. 3: connecting bead 5 one sides is seal wire 8 and 8a, and opposite side is a negative electrode 4, and negative electrode 4 is the deflection shape, in negative electrode 4 is deflected into the helical lamp spiral coil, helical lamp pin 1-2 is highly further shortened.
Claims (2)
1, the rolling sealed type spiral fluorescent lamp comprises helical lamp, and the bead stem stem is characterized in that: it is rolling sealed type that fluorescent tube seals the end.
2, by the described rolling sealed type spiral fluorescent lamp of claim 1, it is characterized in that: tube cathode is deflected in the spiral coil, and fluorescent tube pin portion highly shortens.
