Description

LEUCHTE MIT VIELZAHL VON EINZELNEN REFLEKTORELEMENTEN LIGHT WITH VARIETY OF INDIVIDUAL REFLECTOR ELEMENTS

Die Erfindung betrifft eine Leuchte mit den Merkmalen des Patentanspruchs 1.The invention relates to a lamp with the features of claim 1.

Aufgabe der vorliegenden Erfindung ist es, eine Leuchte zu schaffen, welche eine hohe Lichtausbeute bei der Abstrahlung direkten Lichtes aufweist.The object of the present invention is to provide a luminaire which has a high luminous efficacy in the emission of direct light.

Die Erfindung zeichnet sich dadurch aus, dass durch die Kombination von länglichen Leuchtmitteln einerseits und den diesen zugeordneten, zeilenförmig angeordneten Reflektorelementen andererseits eine hohe Lichtausbeute an direktem Licht erreicht wird. Jedes der Reflektorelemente dient quasi als Fokussierelement für das direkte Licht . Durch die Überlagerung der einzelnen von den Reflektorelementen hervorgerufenen Strahlungen ergibt sich trotz starker Fokussierung im einzelnen Reflektorelement insgesamt eine gleichförmige Beleuchtung, insbesondere beim Einsatz der Leuchte für die Beleuchtung von Arbeitsplätzen.The invention is distinguished by the fact that the combination of elongate illuminants on the one hand and the reflector elements arranged in rows and arranged on the other hand achieves a high luminous efficacy of direct light. Each of the reflector elements serves as a sort of focusing element for direct light. The superimposition of the individual radiations caused by the reflector elements results in uniform illumination overall, despite strong focusing in the individual reflector element, in particular when the luminaire is used for illuminating workplaces.

Bevorzugte Ausführungsformen gehen aus den Unteransprüchen hervor.Preferred embodiments emerge from the subclaims.

Insbesondere ist es von Vorteil, wenn im Gehäuse seitliche Abschattungsbereiche gebildet sind, so dass das direkte Licht nur durch die Reflektormittel auf das Objekt einfällt und das übrige Licht als indirektes Licht an der Oberseite der Leuchte austreten kann. Das nach oben austretende indirekte Licht wird durch die weitere Reflektoranordnung hervorgerufen. Ein besonderer kombinatorischer Effekt ergibt sich erfindungsgemäß dadurch, dass die ersten Reflektormittel das als weiteres Reflektormittel wirkende Band durchdringen, so dass einerseits eine direkte Lichteinstrahlung zur Unterseite hin und andererseits eine nahezu ungestörte Erzeugung von indirektem Licht zur Leuchtenoberseite hin bewirkt wird.In particular, it is advantageous if lateral shading areas are formed in the housing, so that the direct light falls on the object only through the reflector means and the remaining light can emerge as indirect light on the top of the lamp. The indirect light emerging upwards is replaced by the further one Reflector arrangement caused. According to the invention, a particular combinatorial effect results from the fact that the first reflector means penetrate the band acting as a further reflector means, so that on the one hand direct light irradiation towards the underside and on the other hand an almost undisturbed generation of indirect light towards the top of the lamp is effected.

Durch die schalenartige Aufbauweise der erfindungsgemäßen Leuchte ergibt sich zum einen eine leichte Montierbarkeit und zum anderen ein ansprechendes äußeres Design. Die Leuchte kann sowohl als Pendelleuchte als auch als Stehleuchte betrieben werden. Im letzteren Fall erhält sie vorzugsweise im Gehäuse Arretierungsmittel für einen Leuchtenfuß bzw. Leuchtenständer.The shell-like construction of the luminaire according to the invention results on the one hand in easy assembly and on the other hand in an appealing external design. The lamp can be operated both as a pendant lamp and as a floor lamp. In the latter case, it preferably receives locking means for a lamp base or lamp stand in the housing.

Die Erfindung wird im Folgenden anhand eines Ausführungsbeispiels näher erläutert. Dabei zeigenThe invention is explained in more detail below using an exemplary embodiment. Show

Ausführungsbeispiels der Leuchte nach Fig. 1 und 2 mit oberseitig offenem Gehäuse.Embodiment of the lamp of FIGS. 1 and 2 with the housing open at the top.

Das Ausführungsbeispiel zeigt eine Leuchte, die innerhalb eines Gehäuses 1 angeordnet ist . Das Gehäuse 1 besteht aus einer unterseitigen, im Betrieb dem zu beleuchtenden Objekt zugewandten Schale 2 und einer oberseitigen Schale 3, die geeignet miteinander verbindbar sind. Die Verbindung kam dauerhaft ausgelegt sein oder z.B. durch Formschluss auch als wieder zu öffnende Verbindung ausgestaltet sein.The exemplary embodiment shows a lamp which is arranged within a housing 1. The housing 1 consists of a shell 2 on the underside, facing the object to be illuminated during operation, and a shell on the top side 3, which are suitably interconnectable. The connection came to be designed to be permanent or, for example, also to be designed as a connection to be opened again by positive locking.

Im Inneren des Gehäuses befinden sich längliche Leuchtmittel 4, welche mindestens einseitig gesockelt sind. Über die Sockelbereiche sind die Leuchten 4 mit der erforderlichen Betriebsspannung beaufschlagbar. An der dem zu beleuchtenden Objekt zugewandten Unterseite der länglichen Leuchtmittel 4 sind erste Reflektormittel angeordnet, welche im Folgenden beschrieben werden:In the interior of the housing there are elongated illuminants 4, which are capped at least on one side. The lamps 4 can be supplied with the required operating voltage via the base areas. First reflector means, which are described below, are arranged on the underside of the elongated illuminant 4 facing the object to be illuminated:

Wie insbesondere aus Fig. 2 hervorgeht, sind die ersten Reflektormittel durch einzelne Reflektorelemente 6 gebildet, welche derart gestaltet sind, dass jedes der Reflektorelemente 6 vorzugsweise eine parabolförmige Lichtcharakteristik aufweist. Die optischen Achsen der einzelnen Reflektorelemente 6 erstrecken sich jeweils in Richtung des zu beleuchtenden Objektes. Die räumliche Anordnung der einzelnen Reflektorelemente im Bezug auf die länglichen Leuchtmittel 4 ist so gestaltet, dass jeweils mehrere einzelne Reflektorelemente 6 eine zellenförmige Anordnung bilden, die sich entlang der Leuchtmittel 4 erstreckt. Jedem Leuchtmittel 4 ist dabei eine separate Zeile von Reflektorelementen 6 zugeordnet. Wie darüber hinaus aus Fig. 2 hervorgeht, sind bei benachbarten Leuchtmitteln 4 die Zeilen von Reflektorelementen 6 derart zueinander versetzt, dass eine optimale Flächenausfüllung ermöglicht wird, d.h. dass die einzelnen Reflektorelemente 6 einer Zeile auf Lücke im Bezug auf die benachbarte Zeile angeordnet sind. Jedes der Reflektorelemente 6 ist von einem gemeinsamen Haltemittel 5 getragen, welches innerhalb des Gehäuses 1 fixiert ist. Das Haltemittel 5 weist darüber hinaus sich zum Randbereich des Gehäuses erstreckendeAs can be seen in particular from FIG. 2, the first reflector means are formed by individual reflector elements 6, which are designed such that each of the reflector elements 6 preferably has a parabolic light characteristic. The optical axes of the individual reflector elements 6 each extend in the direction of the object to be illuminated. The spatial arrangement of the individual reflector elements in relation to the elongated illuminants 4 is designed such that a plurality of individual reflector elements 6 each form a cellular arrangement that extends along the illuminants 4. Each lamp 4 is assigned a separate row of reflector elements 6. As can furthermore be seen from FIG. 2, the rows of reflector elements 6 in the case of adjacent illuminants 4 are offset from one another in such a way that an optimal area filling is made possible, that is to say that the individual reflector elements 6 of one row are arranged with a gap in relation to the adjacent row. Each of the reflector elements 6 is carried by a common holding means 5, which is fixed within the housing 1. The holding means 5 also extends to the edge region of the housing

Abschattungsbereiche 5a auf, die bewirken, dass Licht der Leuchtmittel 4 nicht durch seitliches direktes Licht auf das Objekt fällt, sondern dass das gesamte direkte Licht durch die Reflektorelemente 6 hindurchtritt und das übrige Licht abgeschattet wird.Shading areas 5a, which cause that light from the illuminants 4 does not fall onto the object through direct direct light, but rather that all the direct light passes through the reflector elements 6 and the remaining light is shadowed.

Ferner ist ein weiteres Reflektormittel vorgesehen, welches durch ein Band 7 gebildet ist, welches sich um die Leuchtmittel 4 herum derart erstreckt, dass seine beschichtete Innenseite das aus dem Leuchtmittel 4 austretende Licht als indirektes Licht auf die Oberseite des Gehäuses reflektiert, so dass es durch die transparente obere Schale 3 austreten kann.Furthermore, a further reflector means is provided which is formed by a band 7 which extends around the illuminants 4 in such a way that its coated inside reflects the light emerging from the illuminants 4 as indirect light onto the top of the housing, so that it passes through the transparent upper shell 3 can emerge.

Das Band 7 ist in denjenigen Bereichen unterbrochen, in denen die ersten Reflektorelemente 6 angeordnet sind, so dass das direkte Licht ungestört hindurch treten kann und das indirekte Licht in diesen Bereichen der Reflektorelemente 6 nur unmerklich beeinflusst wird.The band 7 is interrupted in those areas in which the first reflector elements 6 are arranged, so that the direct light can pass undisturbed and the indirect light in these areas of the reflector elements 6 is influenced only imperceptibly.

Wie aus Fig. 3 hervorgeht, befindet sich auf der einen Seite des Gehäuses 1 im Bereich der Sockel der länglichen Leuchtmittel 4 ein Arretierungsmittel 8 für einen Leuchtenständer 9, durch den auch die elektrischen Anschlüsse für die Leuchtmittel hindurchgeführt werden. As can be seen from FIG. 3, on one side of the housing 1 in the area of the base of the elongated lamps 4 there is a locking means 8 for a lamp stand 9, through which the electrical connections for the lamps are also passed.
