Description

Die Erfindung betrifft eine Beleuchtungseinrichtung für Schaukästen zur gleichmäßigen Belichtung von Bildern od. dgl. auf der inneren Rückwand mittels indirekten Lichtes von im Kasteninnern befindlichen Lichtquellen aus. Der Erfindungsgegenstand bezweckt eine schatten- und reflexfreie Ausleuchtung der zur Schau zu stellenden Gegenstände, insbesondere Fotografien. Besonders bei Schaustellung von Fotografien ergeben schon kleine Wellungen oder Wölbungen der Fotografie bei Benutzung der bekannten Einrichtungen starke Beleuchtungsunterschiede, die sich störend bemerkbar machen. Derartige Beleuchtungsunterschiede «erden bei dem Erfindungsgegenstand mit einfachsten Mitteln sicher verhütet.The invention relates to a lighting device for showcases for even exposure of pictures or the like on the inner rear wall by means of indirect light from light sources located inside the box. The subject of the invention aims to provide shadow-free and reflex-free illumination of the objects to be displayed Objects, in particular photographs. Especially when exhibiting photographs result in even small undulations or bulges in the photograph when using the known ones Facilities strong lighting differences, which are noticeable disturbing. Such lighting differences are most easily grounded in the subject of the invention Funds safely prevented.

Der Erfindung gemäß sind die Lichtquellen rückseitig durch vorzugsweise verstellbare Reflektoren abgeblendet und hinter einem die Schaukastenmitte abdeckenden Reklametransparent angeordnet, das die Lichtstrahlen zerstreut und sowohl auf die Schaufläche als auch auf verstellbare Spiegel wirft, welche das sie treffende Licht gleichmäßig über die Bilder verteilen. Wesentlich bei dieser Vorrichtung ist, daß die Fotografien überhaupt nicht von direktem Licht getroffen werden, sondern ausschließlich von indirektem, also zurückgestrahltem Licht. Infolge der Verstellbarkeit der Spiegel und der die direkte Bestrahlung abschirmenden Reflektoren kann die Lichtverteilung gut geregelt werden.According to the invention, the light sources are preferably through the rear adjustable reflectors dimmed and behind a covering the center of the showcase Placed advertising banners that diffuses the light rays and hits both the Viewing surface as well as on adjustable mirrors, which throws the light that hits them Distribute evenly over the pictures. It is essential in this device that the photographs are not hit by direct light at all, but exclusively of indirect, i.e. reflected light. As a result of the adjustability of the mirrors and the reflectors shielding the direct irradiation can reduce the light distribution be well regulated.

In der Zeichnung ist beispielsweise eine Ausführungsform des Erfindungsgegenstands in der Draufsicht und im senkrechten Ouerschnitt dargestellt.The drawing shows, for example, an embodiment of the subject matter of the invention shown in plan view and in vertical cross section.

In dem Kasten i sind als Lichtquellen zwei elektrische Birnen 2, 3 mittels des Steges j an der Rückwand .I des Kastens angebracht, die nach der Rückseite hin durch etwa halbkuglige Reflektoren 36, 37 abgeschirmt sind. Diese Reflektoren sind verstellbar, so daß die Abstrahlung des Lichts geregelt werden kann. An der Rückwand q. sind ferner zwei schmale Stützen 6 und 7 durch die Schrauben S, 9, io, ii befestigt. 'Mittels Bolzen 12. 13 ist an diesen Stützen der Rahmen 1q. befestigt. In dein Rahmen 14 werden zwei Gläser i3, 16 durch Federn i:;, ig gehalten, die sich mit ihren Endpunkten 20, 21. 22, 23 im Rahmen abstützen. Zwischen den Gläsern 15, 16, deren unteres aus weißem Beinglas besteht, ist eine durchscheinende Ankündigung B eingespannt, die beliebigen Inhalt haben und auch aus mehreren Einzelteilen zusammengesetzt sein kann. An den Seitenwänden des Kastens sind mittels Gelenken 2,9, 29, 30, 31, 32. 33, 34-. 33, die in der Zeichnung lediglich angedeutet sind, Spie,el2-I, 23, 26, 27 verstellbar angeordnet. Diese Spiegel reflektieren das von der Beinglasplatte abgestrahlte Licht, soweit es die Spiegel trifft, auf die Schaufläche hin. Durch Verstellung der Spiegel kann die Lichtverteilung, die, wie oben erwähnt, auch durch die Einstellbarkeit der hinter den elektrischen Birnen 2, 3 angeordneten Reflektoren 36, 37 beeinflußt «-erden kann, weiter geregelt werden, so daß eine gleichmäßige Ausleuchtung der zur Schau gestellten Objekte, beispielsweise Fotografien, erreichbar ist. Insbesondere wird vermieden, daß die in der 'Nähe der Lichtquelle oder in der -Nähe der Spiegel befindlichen Fotos stärker beleuchtet werden als die über die übrige Fläche der Rückwand des Schaukastens verteilten Fotos.In the box i, two electric bulbs 2, 3 are attached as light sources by means of the web j on the rear wall .I of the box, which are shielded towards the rear by approximately hemispherical reflectors 36, 37. These reflectors are adjustable so that the emission of the light can be regulated. On the back wall q. are also two narrow supports 6 and 7 attached by the screws S, 9, io, ii. The frame 1q is attached to these supports by means of bolts 12. 13. attached. In your frame 14 two glasses i3, 16 are held by springs i:;, ig, which are supported with their end points 20, 21, 22, 23 in the frame. Between the glasses 15, 16, the lower part of which consists of white leg glass, a translucent announcement B is clamped, which can have any content and can also be composed of several individual parts. On the side walls of the box are by means of joints 2,9, 29, 30, 31, 32, 33, 34-. 33, which are only indicated in the drawing, Spie, el2-I, 23, 26, 27 are arranged to be adjustable. These mirrors reflect the light emitted by the leg glass plate, as far as it hits the mirror, onto the viewing surface. By adjusting the mirrors, the light distribution, which, as mentioned above, can also be influenced by the adjustability of the reflectors 36, 37 arranged behind the electric bulbs 2, 3, can be further regulated so that uniform illumination of the objects on display Objects, such as photographs, is accessible. In particular, it is avoided that the photos located in the vicinity of the light source or in the vicinity of the mirror are more strongly illuminated than the photos distributed over the remaining area of the rear wall of the showcase.
