Description
Die Erfindung betrifft eine asymmetrisch strahlende Leuchte mit mehreren, in einem Gehäuse nebeneinander angeordneten Spiegeloptiken für jeweils eine stabförmige Lampe, insbesondere zur Verwendung in Spritz- oder Lackierkabinen.The invention relates to an asymmetrically radiating lamp with a plurality of mirror optics arranged side by side in a housing, each for a rod-shaped lamp, in particular for use in spraying or painting booths.
Derartige Leuchten mit asymmetrischer Lichtverteilung zur gleichmäßigen Ausleuchtung senkrechter oder auch waagerechter Flächen sind für verschiedene Anwendungsfälle bekannt (DE-A-1 497 369, DE-U-85 07 634). Die Leuchten haben jeweils einen beweglichen Reflektor oder eine ebensolche Spiegeloptik, um das austretende Licht der Lampe an unterschiedliche Beleuchtungsaufgaben anzupassen. Bei all diesen Leuchten besteht eine feste Zuordnung von Optik und Leuchtengehäuse. Ideale Beleuchtungsverhältnisse, wie sie bei Lackier- und Prüfungsvorgängen notwendig sind, lassen sich jedoch mit den bekannten Leuchten nicht erzielen.Such lights with asymmetrical light distribution for uniform illumination of vertical or horizontal surfaces are known for various applications (DE-A-1 497 369, DE-U-85 07 634). The luminaires each have a movable reflector or mirror optics to adapt the light emitted by the lamp to different lighting tasks. All of these luminaires have a fixed assignment of optics and luminaire housing. However, ideal lighting conditions, such as are necessary for painting and testing processes, cannot be achieved with the known luminaires.
Der Erfindung liegt die Aufgabe zugrunde, eine asymmetrisch strahlende Leuchte so zu gestalten, daß Problemzonen an Spritz- und Lackierobjekten wie beispielsweise Kraftfahrzeugkarosserien optimal ausgeleuchtet und daß zugleich weniger Leuchten benötigt werden. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Weiterbildungen und vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The invention is based on the object of designing an asymmetrically radiating lamp in such a way that problem areas on spraying and painting objects such as, for example, motor vehicle bodies are optimally illuminated and that fewer lamps are required at the same time. This object is achieved by the characterizing features of

Die Leuchte hat ein kastenförmiges, langgestrecktes Leuchtengehäuse (1), welches an seiner Vorderseite mit einer Scheibenabdeckung (2) verschließbar ist, um die für Spritz- und Lackierkabinen erforderlichen FF-Bedingungen einzuhalten. Im Inneren des Leuchtengehäuses, welches sowohl zum Aufbau an einer Wand, als auch zum Einbau innerhalb einer Wand ausgebildet sein kann, sind drei Spiegeloptiken (3, 4, 5) jeweils um eine stabförmige Lampe (6), insbesondere eine Leuchtstofflampe angeordnet, deren Längsachsen vorzugsweise in einer Horizontalen verlaufen. Jede Spiegeloptik besteht aus einem halbkreisförmig um die Lampe greifenden Fangspiegel (3a, 4a, 5a), der in einen parabolisch gekrümmten, schräg strahlenden Umlenkspiegel (3b, 4b, 5b) übergeht. Dabei sind zwei Spiegeloptiken (3, 4) vorzugsweise gleichartig ausgebildet, während die dritte Spiegeloptik (5) einen größeren Umlenkspiegel (5b) mit ausgeprägterer schräg strahlender Charakteristik aufweist. Alle Spiegeloptiken sind jeweils beiderseits durch Stirnwände (3c, 4c, 5c) begrenzt, die die gekrümmten Fang- und Umlenkspiegel stabilisieren. Zugleich bilden die Stirnwände Lagerstellen der Spiegeloptiken an jeweils zwei außenseitig befindlichen Tragteilen (3d, 4d, 5d), die ihrerseits im Leuchtengehäuse (1) verschiebbar und herausnehmbar angeordnet sind.The luminaire has a box-shaped, elongated luminaire housing (1), which can be closed with a pane cover (2) on the front to meet the FF conditions required for spraying and painting booths. In the interior of the luminaire housing, which can be designed both for installation on a wall and for installation within a wall, three mirror optics (3, 4, 5) are each arranged around a rod-shaped lamp (6), in particular a fluorescent lamp, the longitudinal axes of which preferably run horizontally. Each mirror optic consists of a semicircular secondary mirror (3a, 4a, 5a) which merges into a parabolically curved, obliquely radiating deflecting mirror (3b, 4b, 5b). Two mirror optics (3, 4) are preferably of the same design, while the third mirror optics (5) have a larger deflecting mirror (5b) with a more pronounced obliquely radiating characteristic. All mirror optics are delimited on both sides by end walls (3c, 4c, 5c), which stabilize the curved secondary and deflecting mirrors. At the same time, the end walls form bearing points of the mirror optics on two outside supporting parts (3d, 4d, 5d), which in turn are slidably and removably arranged in the lamp housing (1).
An jedem Tragteil (3d, 4d, 5d) ist zur Aufnahme des Lampensockels eine Fassung (6a) befestigt, deren Mittelachse zugleich als Dreh- bzw. Schwenkpunkt der Stirnwände und damit der Spiegeloptik um die entsprechende Lampe dient. Der Schwenkbereich der Spiegeloptiken (3, 4, 5) aus der in Vollinien gezeigten Grundstellung bis in die in Strichlinien gezeigte maximale Kippstellung (3', 4', 5') umfaßt bei den kleineren Optiken (3, 4) etwa 30°, während er bei der größeren Optik (5) etwas geringer ist. Um die Spiegeloptiken in den Zwischenstellungen zu arretieren, sind den Tragteilen jeweils Blechwinkel (3e, 4e, 5e) mit einer Gradeinteilung und mehreren Arretierlöchern zugeordnet, wie insbesondere am oberen Blechwinkel (3e) angedeutet ist. Dabei sind vorzugsweise alle 5°-Schritte durch ein Arretierloch markiert. In die Arretierlöcher rastet ein an der zugehörigen Stirnwand befestigter Federbolzen (3f) ein und hält die Spiegeloptik jeweils in der eingestellten Lage. Zusätzlich sind zum stufenlosen Einstellen und Arretieren der Spiegeloptiken in den Stirnwänden halbringförmige Kulissen (3g, 4g, 5g) ausgespart, durch die zwei in das entsprechende Tragteil eingedrehte Schrauben greifen. Letztere klemmen die Stirnwand und damit die Spiegeloptik in beliebiger Lage des Schwenkbereiches und gewährleisten so eine Feineinstellung.On each support part (3d, 4d, 5d) a socket (6a) is attached to receive the lamp base, the central axis of which also serves as the pivot or pivot point of the end walls and thus the mirror optics around the corresponding lamp. The swivel range of the Mirror optics (3, 4, 5) from the basic position shown in solid lines to the maximum tilt position (3 ', 4', 5 ') shown in broken lines comprises about 30 ° in the smaller optics (3, 4), while in the larger optics (5) is slightly less. In order to lock the mirror optics in the intermediate positions, the supporting parts are each assigned sheet metal angles (3e, 4e, 5e) with a graduation and several locking holes, as indicated in particular on the upper sheet metal angle (3e). All 5 ° steps are preferably marked by a locking hole. A spring bolt (3f) attached to the associated end wall snaps into the locking holes and holds the mirror optics in the set position. In addition, semi-ring-shaped baffles (3g, 4g, 5g) are cut out in the end walls for stepless adjustment and locking of the mirror optics, through which two screws inserted into the corresponding support part engage. The latter clamp the front wall and thus the mirror optics in any position of the swivel range and thus ensure fine adjustment.
Jede Spiegeloptik bildet zusammen mit ihren Tragteilen, Fassungen sowie der Lampe eine feste Baueinheit und ist an lediglich angedeuteten seitlichen Schienen (7) innerhalb des Leuchtengehäuses (1) herausnehmbar gehalten. Dadurch lassen sich die einzelnen Spiegeloptiken am Einbauort der Leuchte auswechseln und gegebenenfalls auch in ihrer Anzahl vermindern. Hierbei können die Tragteile (3d, 4d, 5d) der einzelnen Spiegeloptiken auf den Schienen (7) quer zu den Lampenlängsachsen schlittenartig bewegt werden. Damit wird eine Austauschbarkeit der Optiken innerhalb der Leuchte sowie insbesondere bei einer herausgenommenen Spiegeloptik ein beliebiges Verschieben der beiden verbleibenden Optiken über den Schienenbereich ermöglicht.Each mirror optic, together with its supporting parts, sockets and the lamp, forms a solid structural unit and is held removably on the side rails (7), only indicated, within the lamp housing (1). This allows the individual mirror optics to be replaced at the installation location of the luminaire and, if necessary, reduced in number. The supporting parts (3d, 4d, 5d) of the individual mirror optics on the rails (7) can be moved in a sled-like manner transversely to the longitudinal axes of the lamps. This enables interchangeability of the optics within the luminaire and, in particular if the mirror optics are removed, any movement of the two remaining optics over the rail area.
Für das Auswechseln der Spiegeloptiken sowie zum Lampenwechsel ist die Scheibenabdeckung (2) nach Lösen von Verriegelungsbolzen (2a) an Scharnieren (2b) abklappbar (Fig. 3). Die Scheibenabdeckung hat einen umlaufenden Rahmen, in dem mittels einer Dichtung (2c) ein Zwei-Scheiben-Sicherheitsglas (2d) als Lichtaustrittsfläche eingesetzt ist. Die silikonfrei verarbeitete Dichtung liegt bei geschlossener Scheibenabdeckung fest am Rand des Leuchtengehäuses (1) auf und sorgt für die Einhaltung der FF-Bedingungen. Von der Scheibenabdeckung wird außerdem ein nicht gezeigter Schalter betätigt, der beim Öffnen die Stromzufuhr zu den elektrischen Bauteilen der Leuchte unterbricht. Innerhalb der Leuchte erfolgt die Verschaltung zwischen den elektrischen Bauteilen, beispielsweise den in Reihe hintereinander angeordneten Vorschaltgeräten (8), und den Lampenfassungen über Steckverbinder, so daß ein problemloses Austauschen der Spiegeloptiken im vorbeschriebenen Sinne durchführbar ist.To replace the mirror optics and to change the lamp, the window cover (2) can be folded down on the hinges (2b) after loosening the locking bolts (2a) (Fig. 3). The pane cover has a circumferential frame in which a two-pane safety glass (2d) is inserted as a light exit surface by means of a seal (2c). The silicone-free processed seal lies firmly on the edge of the lamp housing (1) when the pane cover is closed and ensures compliance with the FF conditions. A switch, not shown, is also actuated by the window cover and cuts off the power supply to the electrical components of the lamp when it is opened. The connection between the electrical components, for example the ballasts (8) arranged in series one behind the other, and the lamp holders via plug connectors takes place within the luminaire, so that the mirror optics can be easily exchanged in the manner described above.
Mit der erfindungsgemäßen Leuchte läßt sich besonders vorteilhaft die Lichtverteilung an ein konkretes Beleuchtungs- bzw. Prüfobjekt optimal anpassen, so daß auch die Problemzonen einer lackierten Karosserie gut ausgeleuchtet werden.With the luminaire according to the invention, the light distribution can be particularly advantageously optimally adapted to a specific lighting or test object, so that the problem areas of a painted body are also well illuminated.
Zudem sind z. B. nach einem Wechsel des zu beleuchtenden Objektes (Modellwechsel) die lichttechnischen Möglichkeiten der Leuchte - auch durch den Einsatz neu entwickelter Optiken - erneut nutzbar.In addition, z. B. after changing the object to be illuminated (model change), the lighting options of the luminaire can also be used again - also through the use of newly developed optics.
