Abstract

Light-transmitting cable comprises a flexible, internally smooth and mirror-surfaced waveguide. Lenses are pref. fitted at the ends to vary the optical path. The internal mirror surface may be coloured, and in cross-section the cable may be split into several sections. The cable is pref. covered by a protective tube that can be bent into various shapes. The inside diameter of the cable can be very large to transmit large quantities of light.

Description

Anlage 1 Attachment 1

L I C H T K A B E L B e s c h r e i b u n g Nach dem Stand der Technik wird die Um- und Weiterleitung von Licht auf geraden Teilstrecken durch Spiegel oder in kleinen Querschnitten durch Fasern mit hoher Lichtdurchlässigkeit auf Umwegen zum Bestimmungs- bzw. Nutzungsbereich bewirkt.L I C H T K A B E L B e s h r e i b u n g According to the state of the art is the redirection and forwarding of light on straight sections through mirrors or in small cross-sections through fibers with high light transmission in a roundabout way to the intended or usage area.

Fasern haben eine hohe Dämpfung infolge ihres massiven Querschnittes und Spiegelsysteme sind ortsgebunden und erfordern eine optische Ausrichtung des Strahlenganges.Fibers have a high attenuation due to their massive cross-section and mirror systems are stationary and require optical alignment of the Beam path.

Diese Merkmale sind dann als Nachteile aufzufassen, wenn große Lichtmengen durch hindernde Medien und auf unterschtedlichen Wegen von der Lichtquelle zum Nutzungsbereich geleitet werden sollen.These features are to be regarded as disadvantages when there is a large amount of light through obstructive media and on various routes from the light source to the area of use should be directed.

Hier kann das erfindungsgemäße Lichtkabel vorteilhaft eingesetn werden. Es besteht aus einem flexiblen Hohlleiter mit innen verspiegelter Oberfläche. Diese Lichtkabel ist biegsam und kann dadurch verschlungene Wege zwischen Lichtquelle und Nutzungsbereich überbrücken. Das Lichtkabel ist rundherum geschlossen und trennt den lichtdurchfluteten Hohlraum von den Medien der Umgebung.The light cable according to the invention can advantageously be used here. It consists of a flexible waveguide with an internally mirrored surface. These The light cable is flexible and can thus create winding paths between the light source and bridging the area of use. The light cable is closed all around and separates the light-flooded cavity from the media of the environment.

Die Enden des Lichtkabels können mit optischen Linsen ausgerüstet sein, die dazu dienen, den Lichteinfall zu vergrößern oder den Strahlengang zu verändern.The ends of the light cable can be equipped with optical lenses that serve to increase the incidence of light or to change the beam path.

Die weiterzuleitende Lichtmenge kann von unbeschränkter Größe sein, weil der lichte Querschnitt des Lichtkabels entsprechend groß ausgebildet werden kann.The amount of light to be transmitted can be of unlimited size, because the clear cross-section of the light cable can be made correspondingly large can.

Anlage 2 Die praktische Anwendung bietet sich überall dort an, wo die Lichtquelle gar nicht oder nur mit Schwierigkeiten in den Nutzungsbereich gebracht werden kann, wo also das Lichtkabel die erforderliche Überbrückung darstellt. Appendix 2 The practical application is available wherever the light source is not brought into the area of use at all or only with difficulty where the light cable represents the necessary bridging.

Beispielsweise kann mit Hilfe eines oder mehrerer Lichtkabel das Tageslicht oder die Helligkeit großer Scheinwerfer in die dunklen Arbeitsbereiche von Tauchern geleitet werden.For example, daylight can be used with the help of one or more light cables or the brightness of large spotlights in the dark work areas of divers be directed.

Andere vorteilhafte Möglichkeiten ergeben sich durch gleich= zeitige Ausnutzung einer Lichtquelle für verschiedene Nutzungsbereiche.Other advantageous options result from simultaneous Utilization of a light source for different areas of use.

Oder auch die Lichtumlenkung aus einer starken und schweren Lichtquelle durch ein an der Kopfbedeckung befestigtes Lichtkabel in die Blickrichtung, bei gleichzeitiger Freisetzuns der Hände für Arbeitsaufgaben, kann in sehr verschiedenen Arbeitsgebieten große, bisher nicht gegebene Vorteile bedeuten.Or the deflection of light from a strong and heavy light source through a light cable attached to the headgear in the viewing direction, at Simultaneous release of hands for work tasks can be very different Areas of work mean great advantages that have not been given before.
