Electric incandescent lamp, especially dwarf incandescent lamp, -

The base of electric incandescent lamps are usually attached to the glass bulb with putty. A synthetic resin cement is best suited as a high-strength putty, made from heat-hardening polymers and fillers. Such a putty must be included in the production Temperatures of over 20O ⁰ C are baked out. This cement cannot be used in practice for incandescent lamps with a base which is large in relation to the size of the glass bulb, in particular the Zv / er £ Lö.hiaflipen _t. If the putty mass covers a larger part of the surface of the glass bulb, for example more than 15 % _t , when the putty is jarged for hardening, a large part, in the case of dwarf incandescent lamps, usually the whole glass bulb, is inevitably brought to this high temperature. Here occur in the glass flask adsorbed harmful gases, particularly oxygen and water vapor from diesoa and spoil the gas filling and the vacuum "Would you / ergglühlauipsn Zv '3iE possess a large in. Relation to the glass bulb base, with the usual for other bulbs resin cement 3 ο disgusting, so the lamp would become unusable in a short time

For this reason, such bulbs are sesockelt with a glue that does not only minimal heating needs for its curing 50J odar to significantly below 200 ⁰ C, beispiels- / else with plaster. This base cement has, in turn, a very low mechanical strength and adhesion, which is why its replacement by other means is very desirable.

The present invention consists in the fact that an electric incandescent lamp, in particular a dwarf incandescent lamp, has a base which is large in relation to the size of the glass bulb, so that the area of the glass bulb covered by the base cement is at least 15% of the seed surface. Base cement hardened at at least 2QO ⁰ C, for example synthetic resin cement, is used. The 3rfindung also specifies a method of how such a lamp can be produced without the above-described deficiencies occurring. According to the invention, this is done for this purpose. went that the: base attachment arit-bel of the putty to be hardened at at least 200 ⁰ C ■: at the same time with or before venting bsv /. .Gas filling of the glass bulb is vorgsnoraiaen.

The invention has a pump tube for this point, "ä'as" either T; is attached to a part of the glass bulb protruding from the base, for example κ on the bulb dome, or it has a base that L.

has an opening for the passage of the pump tube to the outside - this makes it possible to pump and ventilate the Make the glass bulb after the base has already been attached to the glass bulb. The simultaneous hardening of the Wockelkitts by increasing the temperature; and / pumping the glass bulb turns out as particularly useful, since this is the one-time heating too two functions are used, namely to harden the 3 putty and sum of gases in the glass bulb.

The area covered by the putty can even amount to over 25% . For comparison, it should be noted that with normal all-purpose incandescent lamps for normal setting voltages, generally only about 2 % of the bulb surface is covered by the cement. In Fig. 1, such a dwarf incandescent lamp is shown with the usual pearl-foot melt-down, in which the tungsten / luminous wire 4 located inside the glass bulb 3 is carried by two strobe supply wires 5 and 5, which are inside the glass bulb 3 by a glass bead? in |

The use of such a cement, hardened at Te rape rat ure η of vrenirjstens ί 200 ⁰ C in a lamp in which the cement mask covers at least 15% of the entire glass surface, was made possible by the fact that the cement does not harden as usual after Pumping and final closing of the lamp bulb was made, but at the same time kit the pumping process or before. The attachment of the pump pole to the piston end enables such a sequence of operations without further ado. It would also be conceivable to attach the pump tube in the usual way at the other end of the lamp bulb (at 12), if the base instead of the floor contact 9 has a sufficiently large opening for the passage of the puncture such bases readily the case, which are only used for mechanical fastening of the lamp, but not as an electrical contact.
