Abstract
The utility model relates to a core stem, in particular to a core stem with three conduction leads of fluorescent lamp, which is characterized in that: wherein, one conduction lead is directly connected between the exhaust pipes for the core stem with hole and the core stem without hole. The fluorescent lamp produced by the core stem is applicable for the lamp circuit with double-contact.
Description
The utility model relates to a kind of stem stem, particularly relates to a kind of three seal wire stem stems of fluorescent-lamp-use.
The stem stem of conventional fluorescent lamps is divided into porose stem stem and atresia stem stem, they are made up of oviduct, blast pipe and two seal wires, its effect be filament supports, conduction current and with the fluorescent tube sealing-in, in system lamp process, carry out exhaust, wash and charge into filler by them.In recent years two resistance triggering interchange point lamp drivers (as the 1W mini light night) and two electric capacity triggering split point lamp drivers (as Chinese patent 94107795.0) having occurred all requires fluorescent lamp wick column must possess three seal wires.This just requires to increase a seal wire outside the blast pipe of existing two seal wire stem stems.Produce this three seal wire stem stems, small lot is just taked to make by hand, will transform button stem machine in enormous quantities.This has all limited the promotion and application of two triggering lighting technologies greatly.
The purpose of this utility model provides a kind of three seal wire stem stems, and it makes simple, is suitable for producing in enormous quantities.
The purpose of this utility model is achieved in that a seal wire directly is set in the middle of the blast pipe of porose stem stem and atresia stem stem.Atresia stem stem blast pipe only plays a supporting role, so directly insert a seal wire what influence it is not had; A seal wire is set in the middle of the porose stem stem blast pipe, through test to blow hole, exhaust, fill thing, what influence sealed-off do not have yet.
The utility model is because directly be provided with a seal wire in the middle of the blast pipe, thereby two common seal wire stem stems are changed into three seal wire stem stems, and is very simple to the change of button stem machine, can realize the streamline production of three seal wire fluorescent tubes.
Concrete structure of the present utility model is provided by accompanying drawing.
Fig. 1 is the atresia stem stem, and the seal wire 1 of increase is set directly in the middle of the blast pipe 2, flattens part and is sealing-in silk 3; Fig. 2 is porose stem stem, and the seal wire 1 of increase also is set directly in the middle of the blast pipe 2, and blast pipe sealed-off burned tip partly is sealing-in silk 3.
Adopt fluorescent lamp that this three seal wire stem stems produce burning-point several thousand hours, chronic leakage do not occur and fluorescent tube bursts phenomenon.
Claims (2)
1. three seal wire stem stems of a stem stem, particularly a kind of fluorescent lamp is characterized in that wherein a seal wire is set directly in the middle of the blast pipe of porose stem stem and atresia stem stem.
2. stem stem according to claim 1 is characterized in that the seal wire in the porose stem stem blast pipe partly is the sealing-in silk at blast pipe sealed-off burned tip, and the seal wire in the atresia stem stem blast pipe is the sealing-in silk flattening part.
