Description
Glødelampe hvis sokkelrom er utfylt med en isolerende skummasse av varmeherdbart kunststoff. Incandescent lamp whose plinth space is filled with an insulating foam mass of thermosetting plastic.
Oppfinnelsen angår en glødelampe hvis The invention relates to an incandescent lamp if
sokkelrom er utfylt med en isolerende skummasse av varmeherdbart kunststoff, særlig et varmeherdbart kondensat av en harpiks av fenolaldehydtypen og et fyllmateriale, og hvor eventuelt den ene av strømtilførselstrådene i sokkelen er utført som sikring. Lampens metallsokkel blir isolert innvendig for å hindre at der oppstår en elektrisk lysbue mellom en av de strøm-førende tilledningstråder i sokkelen og selve metallsokkelen når sikringen i sokkelen smelter som følge av at lampetråden brenner av, idet en slik avbrenning av glø-detråden vanligvis forårsaker at sikringen smelter og på det sted hvor lysbuen opptrer i sokkelen, kan sokkelmetallet smelte og eventuelt smeltes fast til metalldeler i lampeholderen tiltross for at sokkelen er isolert. Dette er meget ufordelaktig, idet det da praktisk talt er umulig å fjerne sokkelen fra holderen uten å beskadige denne. Det er allerede kjent fra hollandsk patent-skrift nr. 78904 å fylle det frie rom i lampe-sokkelen med en skumdannende blanding av novolak og heksametylentetramin. Det er ofte fordelaktig å tilsette denne blanding et fyllstoff som f. eks. malt kunstharpiks, gips eller kalsiumkarbonat. Disse fyllstoffer har en gunstig virkning på verdien av de spesifike volum av skummassen. Det har imidlertid vist seg at ved glødelamper med en slik skumisolering i sokkelen kan der allikevel oppstå en lysbue i sokkelen som bevirker en gjennomsmeltning av denne. plinth space is filled with an insulating foam mass of heat-curable plastic, in particular a heat-curable condensate of a resin of the phenolaldehyde type and a filler material, and where possibly one of the power supply wires in the plinth is designed as a fuse. The lamp's metal base is insulated inside to prevent an electric arc from occurring between one of the current-carrying supply wires in the base and the metal base itself when the fuse in the base melts as a result of the lamp wire burning off, since such burning of the filament usually causes that the fuse melts and at the place where the arc occurs in the socket, the socket metal can melt and possibly be fused to metal parts in the lamp holder despite the socket being insulated. This is very disadvantageous, as it is then practically impossible to remove the base from the holder without damaging it. It is already known from Dutch patent document No. 78904 to fill the free space in the lamp base with a foam-forming mixture of novolak and hexamethylenetetramine. It is often advantageous to add a filler such as e.g. to this mixture. ground synthetic resin, gypsum or calcium carbonate. These fillers have a beneficial effect on the value of the specific volume of the foam mass. However, it has been shown that with incandescent lamps with such foam insulation in the base, an arc can still occur in the base, causing it to melt through.
Man har funnet at ved tilsetning av It has been found that by adding
bestemte fyllstoffer kan man fullstendig hindre en gjennomsmeltning av sokkelen. certain fillers can completely prevent the plinth from melting through.
Ifølge oppfinnelsen inneholder det skumdannende varmeherdbare kunststoff som fyllstoff magnesiumkarbonat eller et magnesiumkarbonatholdig stoff. According to the invention, it contains foam-forming heat-curable plastic as filler magnesium carbonate or a substance containing magnesium carbonate.
Eksempler på slike stoffer som kan an-vendes ifølge oppfinnelsen er: Magnesiumkarbonat, dolomitt MgCOM.CaC03 og andre forbindelser som ved forholdsvis lav tempe-ratur utskiller kullsyre. Examples of such substances which can be used according to the invention are: Magnesium carbonate, dolomite MgCOM.CaC03 and other compounds which at a relatively low temperature secrete carbonic acid.
Et utførelseseksempel på oppfinnelsen skal forklares nærmere under henvisning til tegningen. An embodiment of the invention will be explained in more detail with reference to the drawing.
Tegningen viser et aksialt snitt gjennom en glødelampe ifølge oppfinnelsen. Glødelampen består av en glasskolbe 1 med en glødetråd 2, som er avstøttet ved hjelp av strømtilførselstråder 3, og eventuelt på an-nen måte, f. eks. ved to støttetråder 8. Lampen har ennvidere en sokkel med to ved hjelp av et isolasjonslegeme 4 fra hver-andre adskilte metalldeler 5 og 6, som hver har et hull med en diameter som er litt større enn diameteren av strømtilførsels-trådene. Det frie rom i sokkelen er utfylt med en isolerende skummasse 9 av varmeherdbart kunststoff. Sokkelen er festet til glasskolben 1 ved hjelp av en egnet kitt-masse 7. Inne i den isolerende skummasse kan den ene strømtilførselstråd være utført som sikring. The drawing shows an axial section through an incandescent lamp according to the invention. The incandescent lamp consists of a glass flask 1 with a filament 2, which is supported by power supply wires 3, and possibly in another way, e.g. by two supporting wires 8. The lamp further has a base with two by means of an insulating body 4 from each other separate metal parts 5 and 6, each of which has a hole with a diameter slightly larger than the diameter of the power supply wires. The free space in the plinth is filled with an insulating foam mass 9 of thermosetting plastic. The base is attached to the glass flask 1 using a suitable putty compound 7. Inside the insulating foam compound, one power supply wire can be designed as a fuse.
Før sokkelen festes på glasskolben, blir et lite kvantum av den skumdannende blanding ifølge oppfinnelsen lagt inn i sokkelen. Under kittoperasjonen for befestigelse av sokkelen til glasskolben opphetes sokkelen til 170—200° C. Som følge av denne opp-heting dannes et skum av den skumdanne-de blanding som fyller ut det frie rom i sokkelen. Den tilstedeværende luft og det over-skytende skum kan unnvike gjennom huller i sokkelen. Etterat skummet er herdnet og sokkelen avkjølet, blir strømtilførselstrå-dene fastloddet til sokkelen og derved luk-kes samtidig hullene i sokkelen. Before the base is attached to the glass flask, a small quantity of the foam-forming mixture according to the invention is placed into the base. During the puttying operation for attaching the base to the glass flask, the base is heated to 170-200° C. As a result of this heating, a foam is formed from the foamed mixture which fills the free space in the base. The air present and the overshooting foam can escape through holes in the base. After the foam has hardened and the base has cooled, the power supply wires are soldered to the base and the holes in the base are thereby closed at the same time.
Den skumdannende, varmeherdbare blanding ifølge oppfinnelsen kan f. eks. ha følgende sammensetning: Skumisolerende blanding 1: 5 vektdeler novolakk 1 vektdel heksametylentetramin 0.5 til 2.5 vektdeler magnesiumkarbonat. The foam-forming, heat-curable mixture according to the invention can, e.g. have the following composition: Foam insulating mixture 1: 5 parts by weight novolak 1 part by weight hexamethylenetetramine 0.5 to 2.5 parts by weight magnesium carbonate.
Skumisolerende blanding 11: Foam insulation mixture 11:
5 vektdeler novolakk 1 vektdel heksametylentetramin 2 til 8 vektdeler dolomitt. 5 parts by weight novolak 1 part by weight hexamethylenetetramine 2 to 8 parts by weight dolomite.
Eventuelt kan disse blandinger tilsettes annet fyllstoff, f. eks. for befordring av god skumstruktur. Optionally, other fillers can be added to these mixtures, e.g. for the transport of good foam structure.
Ved en slik glødelampe opptrer ved av- In the case of such an incandescent lamp, the
brenning av glødetråden og derav følgende smeltning av sikringen ingen gjennomsmeltning av sokkelen når sokkelen er utfylt med skumisoleringen I (MgCOK) eller II (dolomitt). Under ellers like forhold med skumisolering hvis MgCO., er erstattet med samme mengde CaCO!S, opptrer i 25 til 50 pst. av tilfellene en gjennomsmeltning av sokkelen og uten noen isolering av sokkelen i 75 til 100 pst. av tilfellene. burning of the filament and consequent melting of the fuse no melting of the base when the base is filled with the foam insulation I (MgCOK) or II (dolomite). Under otherwise equal conditions with foam insulation if MgCO., is replaced with the same amount of CaCO!S, a melt-through of the plinth occurs in 25 to 50 per cent of the cases and without any insulation of the plinth in 75 to 100 per cent of the cases.
