Abstract
The utility model which discloses an annular fluorescent lamp comprises an annular luminescent tube with two ends with sealed lamp core. The two ends of the annular luminescent tube are sealingly connected with holed lamp wicks, and the air discharging pipe in the lamp wick is sealed. During the production process of annular fluorescent lamps, the protective gas can be introduced into one end of the air discharging pipe of the holed lamp wick, and then discharged from the other end of the air discharging pipe of the holed lamp wick. The protective gas flows in the pipe, and the temperature in the pipe can be regulated, and the other impurity gases in the pipe are cleaned, and the fluorescent powder coating layer and the cathode can be protected, of which can cause the annular fluorescent lamp in low luminous decay and in high luminous flux.
Description
＜technical field 〉
The utility model belongs to a kind of circline.
＜background technology 〉
Existing circline is that the annular luminous tube by wick in each sealing-in of two ends constitutes.In described two wicks, one is the atresia wick, and another is porose wick, and the blast pipe external port in the atresia wick is open, the blast pipe external port sealing in the porose wick.The circline of this structure, the space has only the porose stem stem of an end to communicate with atmosphere by blast pipe in the pipe.In manufacture process; need in pipe, to charge into argon gas or nitrogen when fluorescent tube bends with protection fluorescent coating and negative electrode, and the circline of above-mentioned structure can only single-endedly charge into protective gas from porose wick in pipe; its protective gas does not circulate in pipe, and the protection effect is relatively poor.
＜summary of the invention 〉
The circline of prior art structure; its fluorescent tube one end is and the sealing-in of atresia wick; bend in the process in the fluorescent tube heating; charge into the interior protective gas of pipe because of can't in pipe, circulating; its protection effect is relatively poor; fluorescent coating and negative electrode in the pipe all suffer damage, and it is big to make circline exist light decay, the problem that luminous flux is low.
At the problems referred to above, technical solution of the present utility model is: a kind of circline, constitute by the annular luminous tube of wick in each sealing-in of two ends, and its two wicks are porose wick, and the blast pipe in two porose wicks all seals.
In the utility model, the blast pipe aperture in described two porose wicks can be identical.And owing to porose wick in the equal sealing-in in annular luminous tube two ends; make in the heating bend process; protective gas can be charged into from the porose wick of fluorescent tube one end; and from the porose wick of the fluorescent tube other end, discharge; its protection gas can reach the circulation of two ends in pipe; thereby make the temperature in the pipe be subjected to certain adjusting; other foreign gas is washed in the pipe; fluorescent coating and negative electrode have obtained protection; compare with the circline of prior art structure; its light decay can reduce by 5%, and luminous flux can improve 8-9 (1m/ watt).
＜description of drawings 〉
Fig. 1 is the utility model structural representation.
As shown in Figure 1, the utility model is made of annular luminous tube (1) and porose wick (2).The external port of blast pipe (3) is in outside annular luminous tube (1) termination in the porose wick (2).Wick comprises stem stem and assembling electrode two parts thereon, and stem stem is made up of oviduct, blast pipe and seal wire.
＜embodiment 〉
Referring to Fig. 1, porose wick (2) in the annular luminous tube equal sealing-in in (1) two end, in two wicks, its blast pipe (3) external port is all sealed, and the exhaust aperture of two blast pipes is identical.Circline of the present utility model, its two blast pipes external port are respectively after bend pipe operation and deairing step are finished, and successively its port are sealed with flame.Before its two ends blast pipe sealing, in the bend pipe operation, can make protective gas in pipe, reach the circulation of two ends.
Claims (2)
1, a kind of circline, annular luminous tube by wick in each sealing-in of two ends constitutes, described annular luminous tube one end wick is porose wick, blast pipe sealing in this wick, it is characterized in that: described annular luminous tube other end wick also is porose wick, and the blast pipe in its wick also seals.
2, circline according to claim 1 is characterized in that: the blast pipe aperture in described two porose wicks is identical.
