Abstract

The lamp has several light emitting diodes (2) arranged on illuminant carrying strips, where diodes are white or colored. Illuminant carrying strips are parallely mounted on a reflector (4), which is designed in a convex manner. Each illuminant carrying strips are arranged opposite to the rest of strips in an inclined manner. The illuminant carrying strips are provided with transparent lens attachments (5).

Description

Die Erfindung betrifft eine explosionsgeschützte Leuchte, die als Lichtquelle eine Mehrzahl fest auf einem Leuchtmittelträger angeordneter Leuchtdioden aufweist. Derartige Leuchten können beispielsweise als Langfeld-, Streb- oder Kompaktleuchten im Steinkohlenbergbau unter Tage eingesetzt werden.The invention relates to an explosion-proof luminaire, which has a plurality of light-emitting diodes fixedly arranged on a light source carrier as the light source. Such lights can be used, for example, as long-field, longwall or compact lights in hard coal mining underground.

Eine derartige Leuchte wird in der Druckschrift DT 25 31 968 A1 beschrieben. Hier werden mehrere Leuchtdioden zu einer Gruppe in kreisförmiger oder vielseitiger Anordnung zusammengefasst, die dann auf einem Träger angeordnet werden.
Eine Leuchtdiode als Lichtquelle wird auch in der Offenlegungsschrift DE 100 24 427 A1 beschrieben.Such a lamp is described in the document DT 25 31 968 A1. Here, a plurality of light emitting diodes are combined into a group in a circular or versatile arrangement, which are then arranged on a support.
A light-emitting diode as a light source is also described in the published patent application DE 100 24 427 A1.

Von diesem Stand der Technik ausgehend ist es das Problem der Erfindung eine Leuchte anzugeben, die den unterschiedlichen Anforderungen, insbesondere die des Abstrahlwinkels einzelner Leuchtdiodengruppen, gerecht wird.Starting from this prior art, it is the problem of the invention to provide a luminaire which meets the different requirements, in particular the radiation angle of individual light-emitting diode groups.

Dieses Problem wird mit den Merkmalen des Patentanspruchs 1 gelöst. Aus- und Weiterbildungen werden in den Unteransprüchen angegeben.This problem is solved with the features of claim 1. Training and further education are specified in the dependent claims.

Die explosionsgeschützte Leuchte verfügt über einen Leuchtmittelträger, z.B. einen Reflektor, auf dem als Lichtquelle eine Mehrzahl von parallelen Leuchtmittelträgerstreifen mit Leuchtdioden fest angebracht sind. Dabei können ein oder mehrere Leuchtmittelstreifen, vorzugsweise die äußeren, geneigt angeordnet sein. Die Leuchtdioden können weiß oder farbig leuchtend sein. Mehrere Leuchtmittelträgerstreifen können hintereinander verbunden sein, um in der Länge variabel zu sein. Wahlweise sind die Leuchtmittelträgerstreifen mit Linsenaufsätzen versehen, um eine intensivere Leuchtstärke und bessere Lichtstreuung zu erreichen. Ebenfalls wahlweise ist der Leuchtmittelträger (Reflektor) mit den Leuchtmittelträgerstreifen in der Lampenabdeckung befestigt. Der Leuchtmittelträger (Reflektor) ist im Querschnitt flach, konvex oder trapezförmig ausgebildet. Die Abdeckhaube ist im Querschnitt gewölbt oder trapezförmig ausgeführt.The explosion-proof luminaire has a light source carrier, for example a reflector, on which a plurality of light sources are mounted by parallel illuminant carrier strip with light-emitting diodes firmly. In this case, one or more light-emitting strip, preferably the outer, be arranged inclined. The LEDs can be white or colored bright. A plurality of illuminant carrier strips may be connected in series to be variable in length. Optionally, the illuminant carrier strips are provided with lens attachments to achieve a more intense luminosity and better light scattering. Also optionally, the illuminant carrier (reflector) is attached to the illuminant carrier strip in the lamp cover. The illuminant carrier (reflector) is flat, convex or trapezoidal in cross-section. The cover is arched in cross section or trapezoidal.

Ein Ausführungsbeispiel ist in der Zeichnung am Beispiel einer explosionsgeschützten Langfeldleuchte dargestellt und wird im folgenden näher beschrieben.An embodiment is shown in the drawing using the example of an explosion-proof field lamp and will be described in more detail below.

Figur 1 zeigt schematisch den Aufbau einer mit Leuchtdioden ausgerüsteten explosionsgeschützten Langfeldleuchte. Das Gehäuse 1 enthält unter anderem das für die korrekte Stromversorgung der Leuchtmittelträgerstreifen 2 erforderliche elektronische Vorschaltgerät 3. Die Leuchtmittelträgerstreifen 2 sind auf einem konvexen Leuchtmittelträger (Reflektor) 4 - wahlweise aus spiegelndem oder farblich beschichteten Material - angebracht. Zusätzlich befinden sich über den Leuchtdioden 2 transparente Linsenaufsätze 5.FIG. 1 shows schematically the structure of an explosion-proof linear luminaire equipped with light-emitting diodes. The housing 1 contains, inter alia, the electronic ballast 3 required for the correct power supply of the illuminant carrier strips 2. The illuminant carrier strips 2 are mounted on a convex illuminant carrier (reflector) 4, optionally made of specular or color-coated material. In addition, there are 2 transparent lens caps 5 on the LEDs.
