Description

Vorsatzlinsenfilter für elektrische Lichtquellen Die Erfindung betrifft ein Vorsatzlinsenfilter, das zur Anbringung an elektrischen Lichtquellen Verwendung findet.Auxiliary lens filters for electrical light sources The invention relates to an ancillary lens filter that is used for attachment to electrical light sources finds.

Erfindungsgemäß besteht der Werkstoff des Vorsatzlinsenfilters zur Vermeidung von Glas aus erheblich lichtdurchlässiger Phenolharzfolie oder einem gleichwertigen Kunststoff in ebener oder gewölbter Gestaltung. Weiterhin ist erfindungsgemäß die erheblich lichtdurchlässige Folie derart verformt, daß jeder einzelne Lichtstrahl der Lichtquelle zur Vermeidung jeglicher Blendung des Auges menschlicher oder tierischer Lebewesen gebrochen wird. Sodann besteht erfindungsgemäß das Linsenfilter aus zwei übereinanderliegend verbundenen Einzelfolien, von denen jede durch parallel und dicht nebeneinander liegende Rillen mit auf die Rillenlänge abgestimmter Steigung und abgestimmtem Abstande gekennzeichnet ist. Schließlich beruht die Erfindung darin, daß die zu dem Linsenfilter benutzten zwei Folien unter Versetzung um go°, d. h. kreuzweise, fest miteinander verhunden sind, so daß bei senkrechter Lage des Filters die Rillen der einen Folie senkrecht, die der anderen Folie waagerecht liegen.According to the invention, the material of the ancillary lens filter consists of Avoidance of glass made of significantly translucent phenolic resin film or a equivalent plastic in a flat or curved design. Furthermore, is according to the invention the significantly translucent film is deformed in such a way that every single ray of light the light source to avoid any human or animal eye glare Living being is broken. According to the invention, the lens filter then consists of two superimposed connected individual foils, each of which by parallel and closely spaced grooves with a pitch matched to the groove length and coordinated distances. Finally, the invention is based on that the two foils used for the lens filter are offset by go °, d. H. crosswise, firmly connected to each other, so that when the filter is in a vertical position the grooves of one film are vertical, those of the other film are horizontal.
