Description


      Leuchtschirm        für    elektrische Lampen.    Erfindungsgegenstand ist ein mit Leucht  masse     versehener    Schirm     für        elektrische     Lampen, insbesondere für Nachttischlampen,  gleichviel, ob solche durch Batterie oder  Netzstrom     gespeist    werden.  



       Vorzugsweise    ist die Innenseite     des    Schir  mes mit einem aus     Leuchtmasse    bestehenden  Belag versehen.     Letzterer    kann mit einem       durchsichtigen    Schutzüberzug überdeckt sein.  Der     Schirm        kann    aus ganz oder     teilweise     durchsichtigem Material bestehen (z.

   B. Öl  seide, Ölpapier, Pergament,     Pausleinwand,     Stoff,     Zelluloid,    Glas usw.), oder er     kann.     aus     undurchsichtigem    Material bestehen, wo  bei im     letzteren    Falle der     Leuchtmassebelag     zwecks     Erhöhung    der     Reflexwirkung    auf    eine Unterlage von weisser Lackfarbe auf  gebracht werden kann.
