Abstract

The radiant body e.g. lamp (7) consists of two transparent panels continuously connected with each other by a side surface. A rear side scatter panel (5) is located within at least one low voltage fluorescent tube, which transmits the greatest part of the light, distributed on the basis of total reflection is thrown back partly at its reflecting outer edge, in addition to impinge on deflecting elements e.g. depressions, roughness and wrinkles and similar, which deflect the light from the scatter plate (5,8) in the direction of the cover plate (1) at a distance of some centimeters, which then appears in mostly colored light.

Description

Die Erfindung betrifft eine Vorrichtung entsprechend dem Oberbe­ griff des Anspruchs 1.The invention relates to a device according to the Oberbe handle of claim 1.

Leuchtschriften werden bis heute ausnahmslos mit Hochspannungs­ röhren betrieben. Eine gleichmäßige Ausleuchtung der Strukturen wird durch die besonders bei kleinen Schriften unansehnlich große Bautiefe der Anlagen (großer Abstand Röhre-Deckplatte) erreicht. Außerdem ist die gesamte Fertigung-Handarbeit teuer. Das vorgestellte Beleuchtungsv. für Leuchtschr. verwendet die industriell sehr preiswert herzustellenden Niederspannungs- Leuchtstoffröhren (Energiesparlampen usf.) und zeichnet sich durch eine flache Bautiefe aus. Illuminated letters are still used today with high voltage tubes operated. Uniform illumination of the structures is particularly unsightly with small fonts large installation depth of the systems (large distance between tube and cover plate) reached. In addition, the entire manufacturing-manual work is expensive. The presented Illumination for illuminated cabinet uses the low voltage industrial low cost Fluorescent tubes (energy-saving lamps, etc.) and stands out with a shallow depth.  

Das Beleuchtungsverfahren für Leuchtschriften basiert auf einem Sortiment von Leuchtstofflampen geringeren Durchmessers die in verschiedenen Längen und Biegeradien vorliegen. Diese Lampen 7 sind eingebettet in die Streuplatte 5 in die sie den größten Teil des Lichts abgeben. Totalreflexion bewirkt,das ein Anteil den reflektierenden Rand 3 der Platte erreicht und von diesem wieder zurück geworfen wird. In jedem Fall fällt das Licht früher od. später auf die in optimalem Maße Lichtverteilung-Lichtrahlenkung) gesetzten Ablenkelemente 6 (Einsenkungen, Aufrauhungen u.ä.) die es aus der Platte 5 nach vorne lenken. Das Durchlaufen einer noch­ maligen Streuschicht 4 (z. B. Folie) garantiert ein sehr gleich­ mäßiges Treffen auf die transparente Abdeckplatte 1 die durch das Seitenmaterial 2 mit der Streuplatte 5 verbunden ist.The lighting process for neon signs is based on a range of fluorescent lamps of smaller diameter that are available in different lengths and bending radii. These lamps 7 are embedded in the diffusion plate 5 into which they emit most of the light. Total reflection causes a portion to reach the reflecting edge 3 of the plate and to be thrown back by it. In any case, the light falls earlier or later onto the deflection elements 6 (depressions, roughening, etc.) which are set to the optimum extent (light distribution-light radiation deflection) and direct it out of the plate 5 to the front. Passing through another scattering layer 4 (e.g. film) guarantees a very even impact on the transparent cover plate 1 which is connected to the scattering plate 5 by the side material 2 .

Den Leuchteffekt erhöht, wenn die Seitenfläche 2 und die Rückseite der Streuplatte 8 stark reflektierend sind.The lighting effect increases when the side surface 2 and the back of the diffusion plate 8 are highly reflective.

Auch kann die Eingabefläche 9 der Streuplatte halbverspiegelt sein und somit das von der Lampe kommende Licht durchlassen,das von der Streuplatte auf die Lampe zurück fallende jedoch in die Platte zurück spiegeln.The input surface 9 of the diffusion plate can also be semi-reflective and thus allow the light coming from the lamp to pass through, but reflect the light falling back from the diffusion plate onto the lamp back into the plate.

Claims (3)

1. Beleuchtungsverfahren für Leuchtschriften,dadurch gekennzeich­ net, daß die Leuchtkörper stets aus zwei durch eine Seitenflä­ che miteinander verbundenen transparenten Platten bestehen.1. Illumination method for neon signs, characterized in that the luminous body consist of two interconnected by a Seitenflä surface interconnected transparent plates. Einer rückseitigen Streuplatte innerhalb der sich mindestens eine Niederspannungs-Leuchtstoffröhre befindet die den größten Teil des Lichts in sie abgibt welches sich auf Grund von Totalreflexion in ihr verteilt zum Teil auch an ihrer reflek­ tierenden Außenkante zurück geworfen wird um anschließend auf Ablenkelemente (Einsenkungen, Aufrauhungen u.ä. ) zu treffen,die das Licht aus der Streuplatte in Richtung der sich in einigen Zentimetern Abstand befindlichen Deckplatte lenken, welche dann in meist farbigen Licht erscheint.A backing plate inside the at least the largest is a low-voltage fluorescent tube Part of the light emitted into it due to Total reflection in it is partly distributed at its reflec ting outer edge is thrown back to then Deflection elements (depressions, roughening, etc.) to meet the the light from the diffusing plate towards the ones in some Steer the cover plate located centimeters away, which then appears in mostly colored light. 2. Beleuchtungsverfahren für Leuchtschriften nach Anspruch l mit dem besonderen Merkmal,daß die Eingabefläche 9 der Streu­ platte an der Lampe eine Halbverspiegelung aufweist,die ver­ hindert,das sich einmal in der Streuplatte befindliches Licht wieder in Richtung Lampe bewegt und dabei verloren geht.2. Illumination method for neon letters according to claim l with the special feature that the input surface 9 of the diffusion plate on the lamp has a semi-mirroring, which prevents the light that is once in the diffusion plate moves back towards the lamp and is lost.
