Paten τ-Α ν Spruch:Godfather τ-Α ν saying:

Leuchtendes System für indirekte Beleuchtung von Räumen durch ein aus einzelnen, röhrenartigen Beleuchtungskörpern bestehendes System, die an den Enden in Fassungen gelagert sind, dadurch gekennzeichnet, daß die Fassungen mit spiegelnden Flächen bedeckt sind, welche gegen die Achse der Beleuchtungskörper derart geneigt sind, daß die dunklen, von den nicht leuchtenden Fassungen herrührenden Unterbrechungen des leuchtenden Systems vermieden werden.Luminous system for indirect lighting of rooms through a single, system consisting of tubular lighting fixtures, which are mounted at the ends in sockets, characterized in that, that the sockets are covered with reflective surfaces, which against the axis of the lighting fixture in such a way are inclined to the fact that the dark interruptions of the luminous system resulting from the non-luminous versions be avoided.

KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. Die indirekte Beleuchtung von Sälen, Wohnräumen u. dgl. durch elektrische Glühlampen wird gewöhnlich in der Weise ausgeführt, daß in einer für . den Beschauer nicht sichtbaren Rinne zylindrische Beleuchtungskörper aneindergereiht sind, die ihr Licht von der Rinne aus gegen die als Reflektor benutzte Decke strahlen. Die einzelnen Beleuchtungskörper bestehen aus zylindrischen Glasröhren, die anThe indirect lighting of halls, living rooms and the like by means of electric light bulbs is usually carried out in such a way that in a for. invisible to the beholder Gutter cylindrical lighting fixtures are strung together, which give their light from the gutter shine against the ceiling used as a reflector. The individual lighting fixtures exist made of cylindrical glass tubes attached to ίο den Enden zylindrische Metallkontakte besitzen und in entsprechende, gegen die Rinne isolierte Metallfassungen eingelegt werden. Infolge dieser Bauart zeigt das das Licht ausstrahlende System an den Fassungen eine Unterbrechung; man erhält leuchtende Körper abwechselnd mit nicht leuchtenden Fassungen. Dementsprechend werden auch die als Reflektoren benutzten Deckenflächen nicht gleichmäßig beleuchtet, sondern zeigen, besonders in der Nähe des Licht spendenden Systems, stark beleuchtete neben weniger stark beleuchteten Flächen. Bei den heutigen gesteigerten Anforderungen an die Beleuchtungstechnik wird diese Erscheinung als Mangel empfunden.ίο have cylindrical metal contacts at the ends and placed in corresponding metal frames insulated from the gutter. As a result In this type of construction, the light-emitting system shows an interruption on the sockets; one obtains luminous bodies alternating with non-luminous sockets. Accordingly, they are also used as reflectors used ceiling surfaces are not evenly illuminated, but show, especially in the vicinity of the light-emitting system, strongly illuminated next to less strongly illuminated areas. With today's increased Requirements for lighting technology, this phenomenon is perceived as a deficiency. Der Gegenstand der Erfindung soll diesen Mangel dadurch vermeiden, daß die Fassungen der einzelnen Glühlampen durch Spiegelflächen überdeckt werden, die in einem solchen Winkel zur Achse der Beleuchtungskörper ange- ordnet sind, daß sie das Licht der röhrenförmigen Lampen senkrecht zur Röhrenachse reflektieren und dadurch die dunklen Stellen in den Lampenfassungen, die die leuchtende Röhrenkette unterbrechen, vermeiden, also eine möglichst gleichmäßige Bestrahlung der Decke bewirken.The object of the invention is intended to avoid this deficiency in that the versions of the individual incandescent lamps are covered by mirror surfaces that are at such an angle to the axis of the are arranged so that the light from the tubular lamps is perpendicular to the axis of the tube reflect and thereby the dark spots in the lamp sockets, which the glowing Interrupt and avoid the chain of tubes, i.e. irradiation of the Effect ceiling. Auf der Zeichnung ist der Gegenstand der Erfindung in einem Beispiel dargestellt.In the drawing, the subject of the invention is shown in an example. α ist die als Reflektor dienende Decke des zu beleuchtenden Raumes; b ist die Rinne, in der die Beleuchtungskörper gelagert sind; c ist das aus den einzelnen Lampen bestehende leuchtende System; d sind die Lampenfassungen; e sind die reflektierenden Spiegelflächen. α is the ceiling of the room to be illuminated that serves as a reflector; b is the channel in which the lighting fixtures are stored; c is the luminous system consisting of the individual lamps; d are the lamp sockets; e are the reflective mirror surfaces. Die Wirkung der Spiegelflächen β ist aus der Zeichnung ohne weiteres ersichtlich. Das von dem leuchtenden Faden (Kohlenfaden, Metallfaden usw.) ausgestrahlte Licht trifft die geneigten Flächen e und wird in einer Ebene senkrecht zur Röhrenachse reflektiert. Die Fassung wird infolgedessen nicht mehr als dunkle, sondern durch das reflektierende Licht erleuchtete Stelle erscheinen. Die dunklen Stellen an der als Reflektor dienenden Fläche kommen daher in Fortfall. Als spiegelndes Material ist poliertes Metall, Glas, Spiegel, kurz jedes mit wenig Lichtverlust arbeitende, reflektierende Material zu verwenden.The effect of the mirror surfaces β is readily apparent from the drawing. The light emitted by the luminous thread (carbon thread, metal thread, etc.) hits the inclined surfaces e and is reflected in a plane perpendicular to the tube axis. As a result, the frame will no longer appear as a dark, but rather illuminated area by the reflected light. The dark spots on the surface serving as a reflector are therefore no longer needed. Polished metal, glass, mirrors, in short, any reflective material that works with little loss of light can be used as reflective material.
