Abstract

The utility model relates to a button stem in a tube of an energy saving lamp and aims at providing a button stem which is characterized by being provided with a solid amalgam that can effectively locate; an Hg vapor channel is not affected and the quality of a product is higher; besides, the processing is simple and convenient; the cost is not increased. The technical scheme is as follows: the button stem of the lighting tube comprises a glass pipe socket the big opening of which faces to the lower; the middle of the pipe socket is syncretized and fixed with a windpipe provided with the solid amalgam by glass and two pieces of conductive wires spaced by the windpipe; the windpipe is communicated with the inner cavity of the lighting tube and is isolated from the outside; two symmetrical salients are arranged on the inner tube wall of the windpipe; the two salients extrude on the inner tube wall to limit the solid amalgam in the windpipe. The salients are the hot-pressing indentation on the glass windpipe.

Description

Lamp tube core column

Technical field

The utility model relates to a kind of parts of fluorescent tube, specifically is the stem stem in the energy-saving lamp tube.

Background technology

Electricity-saving lamp is because luminous efficiency height, plurality of advantages such as energy-conservation have obtained wideling popularize application at present.Along with the continuous upgrading to the environmental requirement of various product of the continuous lifting of scientific and technological level and the world today, the mercury that adopts in most of electricity-saving lamp products changes solid mercury (being liquid amalgam) into from original liquid mercury.

In the existing electricity-saving lamp, liquid amalgam is positioned in the tracheae on filament limit, tracheae be hedged off from the outer world but with fluorescent tube in communicate, make liquid amalgam be heated after when heating (filament energising), mercury vapour can be overflowed rapidly from tracheae, and to enter in the fluorescent tube inner chamber excitated fluorescent powder luminous.For preventing that liquid amalgam from sliding into the fluorescent tube inner chamber from tracheae, be provided with a block in the tracheae of most fluorescent tubes, so that liquid amalgam is spacing in tracheae.Yet the setting of block has also reduced mercury vapour enters the fluorescent tube inner chamber from tracheae passage, and the deficiency of mercury vapour makes and needs after the electricity-saving lamp energising more time could be luminous fully, influenced the quality and the class of product.

The utility model content

The purpose of this utility model provides a kind of improvement of lamp tube core column, this stem stem should be able to overcome the deficiency of above-mentioned background technology, have the advantages that liquid amalgam can effectively be located, the mercury vapour passage is unaffected, product quality is higher, and process simple and convenient, cost and do not increase again.

The technical scheme that the utility model proposes is:

Lamp tube core column comprises glass horn mouth down at a gulp, and bell-mouthed centre is fixed one with glass frit and is equipped with the tracheae of liquid amalgam and two conductive filaments that separated by tracheae, and tracheae communicates and is hedged off from the outer world with the fluorescent tube inner chamber; Two of being shaped on symmetry on the inner tubal wall of described tracheae are outstanding, give prominence at the inner tubal wall upper process for these two, and liquid amalgam is spacing in tracheae.

Described outstanding be hot pressing impression on the glass tracheae.

It is outstanding that the utility model is made on the inner tubal wall of tracheae, and the pipe internal channel of tracheae is become flat narrow, and liquid amalgam is because of crossing thereby obtain the location; It is less that but the cross section flux of regulation of the pipe internal channel of tracheae but changes, and therefore when fluorescent tube is switched on, can guarantee that the mercury vapour that volatilizees on the liquid amalgam enters the fluorescent tube inner chamber rapidly from tracheae, guaranteed fluorescent lifetime and product quality; In addition, described outstanding making is very simple, only need when tracheae heating deliquescing, to flatten slightly, need not increase cost.

Embodiment

As shown in the figure, be provided with glass horn mouth 2 down at a gulp in this lamp tube core column, tracheae 3 and two conductive filaments 1 that are equipped with liquid amalgam are fixed with glass frit in bell-mouthed centre, and tracheae communicates and is hedged off from the outer world with the fluorescent tube inner chamber; Be shaped on two outstanding 3-1 of symmetry on the inner tubal wall of described tracheae, give prominence at the inner tubal wall upper process for these two, the interior tube section of tracheae is deformed into flat pattern; And liquid amalgam 4 is because cross section is bigger, obtains spacingly thereby just be subjected to mounting board at two highlights, guaranteed that it can not slide into to go in the fluorescent tube inner chamber, thereby (liquid amalgam 4 usefulness double dot dash lines represented among the figure to have the useful life of growing; The fusion detent position of tracheae in the 5 expression subsequent handlings of double dot dash line simultaneously, liquid amalgam is positioned at wherein, the opening by the upper end communicates with the fluorescent tube inner chamber).

The making of described two outstanding 3-1 is also very simple, as long as use the pliers clamp slightly once after the heating of glass tracheae, makes tracheae be deformed into flat form (being the hot pressing impression).

Obviously, also can be only outstanding with one, need only this and give prominence at the enough height of inner tubal wall upper process, can stop liquid amalgam; But comparatively speaking, result of use still is the better of above-mentioned two outstanding structures, makes that to require also be the simpler of above-mentioned two outstanding structures.

Claims

1, lamp tube core column comprises glass horn mouth (2) down at a gulp, and bell-mouthed centre is fixed one with glass frit and is equipped with the tracheae (3) of liquid amalgam (4) and two conductive filaments (1) that separated by tracheae, and tracheae communicates and is hedged off from the outer world with the fluorescent tube inner chamber; It is characterized in that being shaped on the inner tubal wall of described tracheae two outstanding (3-1) of symmetry, give prominence at the inner tubal wall upper process for these two, liquid amalgam is spacing in tracheae.

2, lamp tube core column according to claim 1 is characterized in that described outstanding (3-1) is the hot pressing impression on the glass tracheae.
