Description

       

  Beleuchtungskörper mit     Reffektor.       Die     Erändung    betrifft einen Beleuchtungs  körper mit Reflektor und besteht darin,     dass     der Reflektor durch einen nicht metallischen  Körper, der mit einer diffus reflektierenden       Oberflächenschicht    versehen ist, gebildet ist.

    Nach einer Ausführungsform der Erfindung  sind in die Oberflächenschicht des     Refiektors     kleine unregelmässig liegende, spiegelnde  Teilchen, zum Beispiel Glimmer- oder Glas  teilchen, eingebettet, wobei der Körper des  Reflektors zweckmässig aus einem formbaren       Baustoff    besteht.     SolcheReflektoren        sindwe-          nig    empfindlich gegen Witterungseinflüsse       und    ihre diffus reflektierende Oberfläche ist  sehr widerstandsfähig. Ein wesentlicher Vor  teil     derartigerReflektoren    besteht darin,     dass     sie sehr grosse Abmessungen erhalten können.

    Sie können beispielsweise mit einem Durch  messer bis etwa 2     in    hergestellt werden.  Versuche, ähnliche Reflektoren aus Metall  herzustellen, scheiterten einerseits an der  Schwierigkeit der technischen Ausführung,  anderseits an den hohen Kosten.  



  Als Werkstoff für die Herstellung des       Kdrpers    des Reflektors eignet sich insbeson-         dere        Faserstoff,    der mit einem an sich be  kannten Bindemittel, zum Beispiel Gips, zu  einer Masse vermischt wird, die     gepresst    oder  auch in eine Form gegossen werden kann.  Nach einer vorteilhaften Ausführung wird  die     Oberflächenschicht    des Reflektors mit  einem hellen Hartlack überzogen, in den vor  der Erhärtung feine Glimmer- oder     Glasteil-          eben,    oder gleichwirkende Stoffe unregel  mässig liegend eingebettet werden.  



  In der Zeichnung ist ein Ausführungs  beispiel eines Beleuchtungskörpers gemäss  der Erfindung schematisch dargestellt. Es  bezeichnet a den Reflektor,<B>b</B> eine Lichtquelle,       und   <B>o</B> einen Schirm, beispielsweise aus Milch  glas. Der nach oben gerichtete Teil der von  der Lichtquelle ausgehenden Gesamtstrahlung  wird von der reflektierenden     Oberflächen-          schiebt   <B>-</B> des Reflektors aufgenommen und  diffus in den Raum zerstreut.

  Lighting fixture with reffector. The amendment relates to a lighting body with a reflector and consists in that the reflector is formed by a non-metallic body which is provided with a diffusely reflective surface layer.

    According to one embodiment of the invention, small, irregularly lying, reflective particles, for example mica or glass particles, are embedded in the surface layer of the reflector, the body of the reflector expediently being made of a malleable building material. Such reflectors are not very sensitive to the effects of the weather and their diffusely reflecting surface is very resistant. A major advantage of such reflectors is that they can be given very large dimensions.

    For example, they can be manufactured with a diameter of up to about 2 in. Attempts to manufacture similar reflectors made of metal failed on the one hand because of the difficulty of the technical design and on the other because of the high costs.



  A particularly suitable material for the manufacture of the body of the reflector is fibrous material which is mixed with a binding agent known per se, for example plaster of paris, to form a mass which can be pressed or poured into a mold. According to an advantageous embodiment, the surface layer of the reflector is coated with a light-colored hard lacquer, in which, before hardening, fine mica or glass parts or substances with the same effect are irregularly embedded.



  In the drawing, an embodiment example of a lighting fixture according to the invention is shown schematically. It denotes a the reflector, <B> b </B> a light source, and <B> o </B> a screen, for example made of milk glass. The upwardly directed part of the total radiation emanating from the light source is from the reflecting surface - pushes <B> - </B> the reflector picked up and diffused into the room.



  The drawing is only intended to illustrate the use of the new lighting fixture with reflector. Their shape and arrangement is adapted to the respective purpose. <B> _ </B>
