Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung bezweckt, die von einer Lichtquelle ausgehenden Strahlen nach allen Richtungen hin ganz gleichmäßig zu verteilen. Die bekannten Vorrichtungen, bei denen durch Anordnung flacher Spiegel oberhalb und unterhalb der Lichtquelle eine Zerstreuung der Lichtstrahlen bewirkt wird, haben den Nachteil, daß ein Teil der von der Lichtquelle ausgehenden Strahlen verloren geht, indem dieselben senkrecht auf den oberhalb der Lichtquelle befindlichen Reflektor geworfen werden und demzufolge in derselben Richtung wieder zurückfallen. Die Erfindung beseitigt diesen Nachteil dadurch, daß der oberhalb des Leuchtkörpers angebrachte flache Spiegel in der Mitte mit einem Winkelspiegel versehen ist, wodurch die direkt von der Lichtquelle senkrecht nach* oben fallenden Lichtstrahlen gebrochen und in den zu beleuchtenden Raum zurückgeworfen werden. Durch diese Anordnung wird eine Zerstreuung sämtlicher Lichtstrahlen und demzufolge eine erhöhte Leuchtkraft der Lichtquelle erzielt.The aim of the invention is to direct the rays emanating from a light source to all Distribute directions evenly. The known devices in which by arranging flat mirrors above and below the light source a scattering of the light rays is caused have the disadvantage that part of the The rays emanating from the light source are lost by placing them perpendicular to it thrown the reflector located above the light source and consequently fall back in the same direction. The invention overcomes this disadvantage in that that the flat mirror attached above the filament is provided in the middle with an angled mirror, whereby the light rays falling directly from the light source vertically upwards are refracted and be thrown back into the room to be illuminated. This arrangement causes all light rays to be dispersed and consequently an increased luminosity of the light source is achieved.
Die Erfindung ist in der Zeichnung in Verbindung mit einer Gasglühlichtlampe veranschaulicht. The invention is illustrated in the drawing in connection with a gas incandescent lamp.
Unterhalb der auf dem Gasrohrarm α sitzenden Lampe b ist ein aus mehreren in der Mitte stumpfwinklig zusammenstoßenden Teilspiegeln gebildeter Spiegel c vorgesehen, der mit dem Gasrohr abnehmbar verbunden ist. Oberhalb der Lampe ist an einem Arm b ein Planspiegel e befestigt, der gemäß vorliegender Erfindung in der Mitte einen Winkelspiegel / trägt.Below the lamp b seated on the gas tube arm α , a mirror c formed from a plurality of partial mirrors which collide at an obtuse angle in the middle is provided, which is detachably connected to the gas tube. Above the lamp, a plane mirror e is attached to an arm b which, according to the present invention, carries an angled mirror / in the middle.
Die Brechung und Verteilung der Lichtstrahlen ist zum Teil in der Zeichnung veranschaulicht. The refraction and distribution of the light rays is partially illustrated in the drawing.
Ein Teil der Strahlen fällt ungebrochen in den zu beleuchtenden Raum, während die übrigen Strahlen teils auf den Spiegel c, teils auf den Planspiegel e und den Winkelspiegel/ fallen. Der Spiegel c wirft die Lichtstrahlen teilweise in den äußeren Raum und teilweise auf den Planspiegel e, welcher sie nach verschiedenen Richtungen hin verteilt. Die von der Lichtquelle direkt auf den Spiegel/ senkrecht nach oben fallenden Strahlen werden ebenfalls in den freien Raum zurückgeworfen.Some of the rays fall unbroken into the room to be illuminated, while the remaining rays fall partly on mirror c, partly on plane mirror e and the corner mirror /. The mirror c throws the light rays partly into the outer space and partly onto the plane mirror e, which distributes them in different directions. The rays falling from the light source directly onto the mirror / vertically upwards are also reflected back into the free space.
