Abstract
Description
Die Erfindung betrifft eine Leuchte mit den Merkmalen des Anspruchs 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.Object of the present invention is to create a lamp that has a high luminous efficacy has direct light when emitted.
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 characterized by this from that through the combination of elongated bulbs on the one hand and the associated reflector elements arranged in rows on the other hand, a high luminous efficacy of direct light is achieved becomes. Each of the reflector elements serves as a sort of focusing element for the direct light. Through the overlay of the individual radiations caused by the reflector elements arises despite strong focusing in the individual reflector element overall a uniform Lighting, especially when using the luminaire for lighting of jobs.
Bevorzugte Ausführungsformen gehen aus den Unteransprüchen hervor.Preferred embodiments are based on the dependent claims out.
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.It is particularly advantageous if in the housing lateral shading areas are formed, so that the direct Light falls on the object only through the reflector means and the rest Light can escape as indirect light on the top of the lamp. The indirect light emerging upwards is created by the further reflector arrangement caused. According to the invention, a particular combinatorial effect results from that the first reflector means that as a further reflector means penetrate the effective band, so that on the one hand direct light towards the bottom and on the other hand an almost undisturbed generation from indirect light to the top of the luminaire.
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.Due to the shell-like construction the lamp of the invention on the one hand there is easy assembly and on the other hand an attractive outer design. The lamp can be used both as a pendant lamp and as a floor lamp operate. In the latter case, it preferably receives locking means in the housing for a lamp stand or lamp stand.
