Abstract

Construction of a fluorescent lamp bulb of which a portion has been hot moulded according to certain criteria and arrangements which enable the lamp bulb to perform the different functions proper to its operation, in other words: its electronic emission; its power supply; its fixing. It is comprised of a tube (10) having at one end two molded parts (1, 2) which are hollow and have the same shapes. Said moulded parts are separated from each other by their base (14) which is arranged to enable the incorporation of a tube (3). Each moulded part receives a set of electrodes-filament (4, 6) (5, 7), secured at the extremity of the housing (1, 2) by glass-metal welding (20, 21), in such a way that each filament (6, 7) faces the tube (10). The electromechanical elements (4, 6) (5, 7) being thus fixed in the moulded parts, the lamp bulb is closed at its second extremity by a round or flat bottom (15).

Description

" Ampoule fluorescente à culot , à fonctions centralisées " . "Fluorescent bulb with base, with centralized functions".
La présente invention concerne une ampoule d'éclairage électrique, de type lampe fluorescente, à cathodes chaudes basse pression et solide luminescent, à culot et à fonctions centralisées , à savoir :The present invention relates to an electric light bulb, of the fluorescent lamp type, with low pressure hot cathodes and luminescent solid, with base and with centralized functions, namely:
- son émission électronique- its electronic transmission
- son alimentation- its food
- sa fixation- its fixation
De par sa fabrication inédite et sa forme compacte, elle s'apparente sans mal à une ampoule à incandescence, d'autant qu'elle en a la taille et de nombreux points communs .Thanks to its original production and its compact shape, it easily looks like an incandescent bulb, especially as it has the size and many common points.
L'ampoule constituée d'un tube (12) de verre spécial , ou autre forme ou autre matériau, est délimité à une extrémité par un fond (15) rond ou plat, et à l'autre , par deux parties moulées (1,2) creuses et d'égales dimensions, de forme tronconique , et reliées au tube (10) par leur base, laquelle étant aménagée , (14), permet l'implantation d'un queusot (3). Les parties moulées ou logements (1,2) ont pour fonction de loger individuellement chaque ensemble électrodes-filament (4,6)(5,7) lesquels sont disposés filament face à l'intérieur du tube, dans l'espace maximum de la partie moulée . Une soudure courte verre-métal (20,21) à chaque extrémité des logements, permet aux filaments d'être à environ sept millimètres du bord intérieur du tube droit (10) ou de la partie séparant les deux logements . Elles sont conçues avec une ouverture suffisante pour permettre l'émission de décharges électroniques dans la vapeur de mercure, laquelle émet alors des ultra-violets qui excitent la surface de poudre (12) fluorescente collée à l'intérieur du tube . le disposition séparée, distincte des deux filaments émetteurs (6,7) mais assez proche, réduit les difficultés d'amorçage , mais dont leurs logements évitent leur bombardement réciproque, source de dégazage et de destruction lente des filaments, des terres rares fixées sur les filaments , et des électrodes ; les ensembles se détruisant par volatilisation , disposition qui allonge d'autant la durée de vie de la lampe .The bulb consisting of a tube (12) of special glass, or other shape or other material, is delimited at one end by a round or flat bottom (15), and at the other, by two molded parts (1, 2) hollow and of equal dimensions, of frustoconical shape, and connected to the tube (10) by their base, which being arranged, (14), allows the installation of a queusot (3). The molded parts or housings (1,2) have the function of individually housing each electrode-filament assembly (4,6) (5,7) which are arranged filament facing the inside of the tube, in the maximum space of the molded part. A short glass-to-metal weld (20,21) at each end of the housings allows the filaments to be about seven millimeters from the inside edge of the straight tube (10) or the part separating the two housings. They are designed with a sufficient opening to allow the emission of electronic discharges in the mercury vapor, which then emits ultraviolet which excites the surface of fluorescent powder (12) stuck inside the tube. the separate arrangement, distinct from the two emitting filaments (6,7) but fairly close, reduces the priming difficulties, but whose housings avoid their mutual bombardment, source of degassing and slow destruction of the filaments, rare earths fixed on the filaments, and electrodes; the assemblies destroying themselves by volatilization, a provision which lengthens the lamp life accordingly.
La forme tronconique permet à chaque ensemble de se comporter comme un canon à électron , en projetant sans recevoir, et de balayer chaque paroi du tube , ou l'ensemble constitué et recouvert de pâte fluorescente .The frustoconical shape allows each set to behave like an electron gun, projecting without receiving, and to sweep each wall of the tube, or the set made up and covered with fluorescent paste.
Le tube est une enceinte à décharge . La réalisation de l'ensemble (1,3,2,20,21) fait qu'il s'insère dans les culots disponibles dans le commerce .The tube is a discharge vessel. The production of the assembly (1,3,2,20,21) means that it fits into the commercially available caps.
Le queusot soudé directement ou sur son amorce de moulage, permet outre son rôle dévolu quand à la mise sur pompe et scellement, le garnissage de l'ampoule en pâte . Une aiguille creuse ou drain de diamètre inférieur au diamètre libre du queusot , est descendue jusqu'au fond de l'ampoule (15), et la remplit jusqu'au niveau (14) séparant les ensembles émetteurs . Une cellule photo-électrique ou un palpeur réglé à ce niveau (14) arrête alors le remplissage, et inverse l'opération en débarassant l'ampoule de l'excédent de pâte fluorescente, cette opération étant effectuée ampoule debout et à la pression atmosphérique de façon à ne pas inonder et détériorer les ensembles émetteurs protégés localement de la montée du liquide par la surpression d'air .The tail welded directly or on its molding primer, allows in addition to its intended role when the pumping and sealing, the filling of the bulb in paste. A hollow needle or drain with a diameter less than the free diameter of the socket, is lowered to the bottom of the bulb (15), and fills it up to the level (14) separating the emitter assemblies. A photoelectric cell or a probe set to this level (14) then stops filling, and reverses the operation by removing the bulb from the excess fluorescent paste, this operation being carried out with the bulb standing and at atmospheric pressure of so as not to flood and damage the transmitter assemblies locally protected from the rise of the liquid by air overpressure.
Par ailleurs , un tel saupoudrage de ces cavitésFurthermore, such a dusting of these cavities
(1,2) amènerait une luminosité difficilement focalisable et une chaleur minime mais supplémentaire . De ce fait , les bagues métalliques de protection de dégazage à l'aplomb des filaments sur la poudre fluorescente n'ont pas d'utilité .(1,2) would bring a difficult to focus brightness and minimal but additional heat. Therefore, the metal degassing protection rings plumb with the filaments on the fluorescent powder are of no use.
L'ampoule une fois enduite de pâte fluorescente est chauffée doucement et mise sur pompe afin de détruire le liant de la pâte .The bulb, once coated with fluorescent paste, is gently heated and placed on a pump in order to destroy the binder of the paste.
Ensuite , introduction des goutelettes de mercure traité , et mise sur pompe définitive, mise sous vide , puis remplissage par de l'argon sous circuit scellé, puis scellement de l'ampoule la rendant apte à fonctionner .Then, introduction of the treated mercury droplets, and final pumping, vacuum, then filling with argon under a sealed circuit, then sealing the bulb making it suitable for operation.
La trés bonne position du queusot permet un scellement court entre les parties moulées, et l'enfichage de l'ensemble .The very good position of the queusot allows a short sealing between the molded parts, and the insertion of the assembly.
Les électrodes sont reliées suivant un circuit propre .The electrodes are connected in their own circuit.
L'ensemble des parties moulées et ou soudées ,All the molded and or welded parts,
(1,2) et aménagées pour l'implantation du queusot représente l'essentiel de l'invention , et il est de taille extrapolable . (1,2) and arranged for the installation of the queusot represents the essence of the invention, and it is of extrapolable size.
