n Leuchte " n lamp "
Die vorliegende Neueriing betrifft eine Leuchte, bei welcher eine Lichtquelle am einen Ende eines röhrenartigen Leuchtenschirms angeordnet ist, der mit inneren, ringförmigen, in solchem Abstand voneinander angeordneten Vorsprüngen versehen ist, daß Lichtstrahlen von der Lichtquelle nur die gegen die Lichtquelle gekehrten Flächen der Vorsprünge treffen.The present innovation relates to a lamp in which a light source is arranged at one end of a tubular lampshade with inner, annular, in Such spaced projections is provided that light rays from the light source only the opposite the light source facing surfaces of the projections hit.
Dadurch wird Reflexion an den Wänden des Leuchtenschirms vermieden und eine Person, die die Lichtquelle nicht sehen kann, hat nur den Eindruck von indirekter Beleuchtung.This avoids reflection on the walls of the lampshade and a person who cannot see the light source can only have the impression of indirect lighting.
Bei den bisher bekannten Leuchtenschirmen sind die ringförmigen Vorsprünge bisher entweder in der Form von konzentrischen Ringen angeordnet oder man hat im fertigen Leuchtenschirm auf einer Drehbank eine Anzahl von Rillen eingedreht, wodurch eine Reihe von Arbeitsgängen notwendig gewesen ist mit dem Ergebnis, daß solche Armaturen verhältnismäßig teuer waren.In the previously known lampshades, the annular projections have so far either been in the form of concentric ones Arranged in rings or you have turned a number of grooves in the finished lampshade on a lathe, whereby a series of operations has been necessary, with the result that such fittings are relatively expensive was.

Die Neuerung bezweckt, diesen Nachteil zu "beseitigen und einen leuchtenschirm der erwähnten Art herzustellen, welcher billig in Massenfertigung hergestellt werden kann.The aim of the innovation is to "eliminate this disadvantage and to manufacture a lampshade of the type mentioned, which can be mass-produced cheaply.
Dies wird neuerungsgemäß dadurch erreicht, daß die 'Vorsprunge als Gänge eines Innengewindes ausgebildet sind. Zweckmäßig wird der röhrenartige !Leuchtenschirm im Spritz gußverfahren in einer Form mit zentralem Gewindedorn hergestellt mit nachfolgendem automatischen Ausschrauben des Gewindedorne.This is achieved according to the invention in that the 'projections are designed as turns of an internal thread. The tube-like! Lampshade in spray is useful casting process produced in a form with a central threaded mandrel with subsequent automatic unscrewing of the Thread mandrels.
Die Neuerung wird im folgenden näher anhand der Zeichnung eines Ausführungsbeispiels erklärt; es zeigenThe innovation is explained in more detail below with reference to the drawing of an exemplary embodiment; show it

Die g©s®ig"te Leuch.%* iJSS-feefit ans einem röhrenföjmigen Schirm 10 aus einem für Lichtstrahlen nicht durchlässigen Material, vorzugsweise einem Kunststoff, welcher zur Verarbeitung im Spritzgußverfahren geeignet ist.The good light.% * IJSS-feefit on a tubular Screen 10 made of a non-permeable for light rays Material, preferably a plastic, which is suitable for processing by injection molding.
Der Schirm kann in nicht gezeigter Weise so angebracht werden, daß das eine Ende eine Lichtquelle 12 umgibt, um Streuung der Lichtstrahlen an der Schirmwand zu vermeiden, so daß die Beleuchtung als indirekt wirkt ohne störende Reflexe, ist die Innenwand des röhrenartigen Schirms nahezu ganz mit einem Gewinde 16 versehen. Der obere Teil der Innenwand hat einen gewindefreien Teil 14.The screen can be attached in a manner not shown be that one end surrounds a light source 12 in order to avoid scattering of the light rays on the screen wall, so that the lighting acts as indirect without disturbing reflections, the inner wall of the tube-like screen is almost completely provided with a thread 16. The upper part of the inner wall has a thread-free part 14.
Als Beispiel kann zur Erreichung der gewünschten optischen Wirkung die Gewindesteigung etwa 2 mm sein mit einer Gewindetiefe von etwa 0,7 mm bei einem etwa 15 cm langen röhrenartigen Schirm, dessen Durchmesser 135 5 cm beträgt.As an example, to achieve the desired optical effect, the thread pitch can be about 2 mm with a thread depth of about 0.7 mm for an approximately 15 cm long tubular screen, the diameter of which is 13 5 5 cm.
Die äußere Mantelfläche des röhrenartigen Leuchtenschirms ist vorzugsweise mit einer Anzahl axial verlaufender Rippen 18 versehen, wodurch der Schirm in der Form während des !*! Äusschraubens des Domes festgehalten ist.The outer surface of the tubular lampshade is preferably provided with a number of axially extending ribs 18, whereby the screen in the shape during the ! *! Screwing the dome is recorded.
Die Spritzgußform kann inwendig mit einer geringen Konizität ausgebildet sein.The inside of the injection mold can be designed with a slight conicity.
Ss ist dadurch leichter möglich, nach dem Spritzgießen durch Axialverschiebung des Gewindedorns den leuchtenschirm teilweise aus der Porm auszuziehen, jedoch nur so weit, daß die Enden der axial verlaufenden Rippen 18 sich noch in der Form befinden, bö daß dad-ar-c-h die Röhre gegen Drehung gesichert ist,bis der Gewindedorn ausgeschraubt ist.This makes it easier to do after injection molding Axial displacement of the threaded mandrel to partially pull the lampshade out of the Porm, but only so far that the Ends of the axially extending ribs 18 are still in the form, bö that dad-ar-c-h secured the tube against rotation until the mandrel is unscrewed.
Um ein schnelles Ausschrauben zu erreichen, ist das Gewinde des Gewindedorns vorzugsweise mehrgängig.In order to achieve a quick unscrewing, the thread of the threaded mandrel is preferably multi-start.
