Abstract
Transparente Abdeckungen für explosionsgeschützte Leuchten sollen dahingehend verbessert werden, dass Lichtstreuung, Blendfreiheit und Lichtausbeute optimiert werden. DOLLAR A Für diese Verbesserung wird vorgeschlagen, die transparente Leuchtenabdeckung an der äußeren Oberfläche im Bereich der Lichtquelle(n) (z. B. Leuchtstofflampen) mit ein oder mehreren konvexen Erhebungen zu versehen.Transparent covers for explosion-proof luminaires are to be improved so that light scattering, glare-free and light output are optimized. DOLLAR A For this improvement, it is proposed to provide the transparent luminaire cover on the outer surface in the region of the light source (s) (eg fluorescent lamps) with one or more convex elevations.
Description
Für explosionsgeschützte Leuchten existieren bisher transparente Abdeckungen aus Kunststoff oder Glas, die entweder klardurchsichtig oder auf verschiedenste Weise – durch Rippung, Riffelung, Mattierung etc. – strukturiert sind. Im zweiten Fall wird mit der jeweiligen Strukturierung bewirkt, dass die Lichtstrahlen der hinter der Abdeckung befindlichen Lichtquellen (z.B. Leuchtstofflampen) gestreut werden und gleichzeitig Blendeffekte vermieden werden. Ebenso bedeuten diese Konstruktionen jedoch, dass die Lichtstrahlen mittels der Strukturierung stark gebrochen werden, um die beabsichtigten Wirkungen zu erzielen, und das führt zwangsläufig zu einem gewissen Verlust bei der Lichtausbeute.For explosion-proof lights transparent covers made of plastic or glass exist so far, either clear or in many different ways - through Ribbing, ribbing, matting etc. - are structured. In the second Case is caused with the respective structuring that the light rays the light sources behind the cover (e.g., fluorescent lamps) scattered while avoiding glare effects. Likewise, these constructions mean that the light rays be heavily broken by structuring the intended To achieve effects and that leads inevitably to a certain loss in light output.

Der Erfindung liegt das Problem zugrunde, transparente Leuchtenabdeckungen – ob klar-transparent oder in Kombination mit einer Strukturierung – so zu gestalten, dass eine optimale, blendfreie Lichtstreuung erreicht wird, ohne die Lichtausbeute zu beeinträchtigen.Of the The invention is based on the problem of transparent light covers - whether clear-transparent or in combination with a structuring - to shape that one optimal, glare-free light scattering is achieved without the light output to impair.
Dieses Problem wird mit den Merkmalen des Patentanspruchs 1 gelöst. Die Leuchtenabdeckung besitzt an der äußeren Oberfläche min destens im Bereich über der Lichtquelle ein oder mehrere konvexe Erhebungen, die bei zusammengebauter und angeschalteter Leuchte dafür sorgen, dass die Lichtstrahlen der dahinterliegenden Lichtquelle(n) gleichmäßig und blendfrei verteilt werden, ohne dass die Lichtausbeute eingeschränkt wird.This Problem is solved with the features of claim 1. The Luminaire cover has at least on the outer surface in the area above the light source one or more convex elevations, which when assembled and switched on light for it ensure that the light rays of the underlying light source (s) evenly and be distributed without glare, without the light output is limited.
Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen am Beispiel einer explosionsgeschützten Langfeldleuchte dargestellt und wird im folgenden näher beschrieben.One embodiment The invention is in the drawings using the example of an explosion-proof field lamp and will be described in more detail below.
