Elektrische Raumleuchte.Electric room light.
Es wurde die Aufgabe gestellt, eine möglichst flache elektrische Raumleuchte zu entwickeln, die zur blendungsfreien Darstellung leuchtender Bilder, beispielsweise leuchtender Wandbilder geeignet ist. In ähnlicher Ausführung soll die Leuchte mit einem Fuß versehen sein, um sie als Standleuchte, beispielsweise als Fernsehleuchte verwenden zu können. Bei der Standleuchte soll die Möglichkeit eines leichten und schnellen Bildwechsels bestehen, ohne die Leuchte öffnen zu müssen.The task was to develop an electric room lamp that was as flat as possible and that would allow for glare-free display luminous pictures, for example luminous murals is suitable. In a similar design, the lamp should have one foot be provided in order to be able to use them as a floor lamp, for example as a television light. In the case of the floor lamp, the The picture can be changed quickly and easily without having to open the lamp.
Als Lösung der Aufgabe wurden die nachstehend beschriebenen Anordnungen gefunden, die eine flache Form besitzen und bei denen eine blendungsfreie Lichtabgabe durch Reflektion erfolgt. Zur reflektiven Lichtabgabe sind lichtleitende Werkstoffe gewählt. Solche lichtleitenden Werkstoffe sind zum Beispiel Glas oder Polymethylmethacrylat. Scheiben aus lichtleitenden Werkstoffen werden im folgenden Lichtleitscheiben genannt. Andere Formen des lichtleitenden Werkstoffes werden im folgenden Lichtleitstäbe genannt.As a solution to the problem, the following arrangements have been made found, which have a flat shape and in which a glare-free light emission takes place through reflection. To the reflective light emission, light-conducting materials are selected. Such light-conducting materials are, for example, glass or Polymethyl methacrylate. Panes made of light-guiding materials are referred to below as light-guiding panels. Other forms of the Light-guiding material are called light-guiding rods in the following.
Gemäß Figur 1 sind in Rahmenteilen 1, beispielsweioe Teile von Eilderrahmen, elektrische Lichtquellen 2 derart verdeckt angeordnet, daß der Lichtstrom nur durch die Schlitze 3 oder anstelle der Schlitze durch entsprechende Bohrungen austreten kann. Die Lichtstrahlen der Lichtquellen 2 treffen auf die Stirnseite der innerhalb des Schlitzes 3 angeordneten Lichtleitscheibe 4, dringen in diese ein, setzen sich innerhalb der Lichtleitscheibe 4 in verschiedenen Richtungen fort und werden im weiteren Verlauf an der Scheibenoberfläche stets nach dem Scheibeninneren gebrochen. Eine so beleuchtete glasklare Lichtleitscheibe erscheint, in Richtung auf die Scheibenfläche gesehen, dunkel. In Figur 2 ist dargestellt, daß ein Lichtaustritt aus einer Fläche der Lichtleitscheibe 4 erst infolge vonAccording to Figure 1 are in frame parts 1, for example parts of Eilderrahmen, electrical light sources 2 arranged in such a hidden way, that the luminous flux emerge only through the slots 3 or instead of the slots through corresponding holes can. The light rays from the light sources 2 strike the end face of the light guide disk arranged within the slot 3 4, penetrate into this, continue within the light guide plate 4 in different directions and become in the further course on the surface of the pane always broken towards the inside of the pane. A crystal-clear light guide plate illuminated in this way appears dark when viewed in the direction of the disk surface. In Figure 2 it is shown that a light exit from a surface of the light guide 4 only as a result of
Blatt 2page 2
Reflektion stattfindet, wenn sich auf der gegenüberliegenden Scheibenfläche eine homogen aufgetragene Farbschicht 5, beispielsweise ein auf die Lichtleitscheibe 4 unmittelbar aufgemaltes odef aufgedrucktes Bild, befindet.Reflection takes place when looking at the opposite Disc surface a homogeneously applied color layer 5, for example one that is painted directly on the light guide disc 4 odef imprinted image.
Der von der Lichtquelle 2 ausgehende Lichtstrom verteilt sich innerhalb der gesamten Lichtleitscheibe 4? daher erfolgt die reflektive Abstrahlung in den Raum flächenhaft von der gesamten Farbschicht 5. Durch die großflächige Verteilung des Lichtstrooies wirkt die Lichtabstrahlung in den Raum diffus und blendungsfrei. The luminous flux emanating from the light source 2 is distributed within the entire light guide 4? therefore the reflective radiation into the room takes place over a large area from the entire room Color layer 5. Due to the large-area distribution of the lightstrooies the light radiation into the room has a diffuse and glare-free effect.
Wird an bestimmten Stellen der Lichtleitscheibe 4 ein stärkerer Lichtaustritt gewünscht, zum Beispiel als Umrandung von Bildkonturen, dann werden die betreffenden Konturen gemäß Figur 2 mit einer Gravur 6 versehen und die Gravuren gegebenenfalls zusätzlich hell gefärbt.If a stronger light exit is desired at certain points of the light guide disk 4, for example as a border around Image contours, then the contours in question are provided with an engraving 6 according to FIG. 2 and the engravings if necessary additionally brightly colored.
Die gemäß Figur 1 beschriebenen Rahroenteile 1 mit den darin befindlichen Lichtquellen 2 lassen sich in Form eines geschlossenen Rahmens, zum Beispiel eines Bilderrahraens, anordnen. Andere Rahmenformen sind denkbar. In Figur 3 ist beispielsweise eine U-fÖrmige Anordnung der die Lichtquellen enthaltenden Rahmenteile 1 dargestellt. Diese U-Form des Rahmens erlaubt ein leichtes Auswechseln der Lichtleitscheibe 4 gegen eine andere durch einfaches Herausziehen der einen und Einschieben einer anderen Lichtleitscheibe, ohne den Rahmen öffnen zu müssen.The frame parts 1 described according to Figure 1 with the therein The light sources 2 located there can be arranged in the form of a closed frame, for example a picture frame. Other frame shapes are conceivable. In Figure 3, for example a U-shaped arrangement of the frame parts 1 containing the light sources is shown. This U-shape of the frame allowed an easy exchange of the light guide plate 4 for another by simply pulling out one and pushing it in another light guide without having to open the frame.
Sollen bestimmte Sektoren der Lichtleitscheibe konzentriert, gestreut oder gerichtet ausgeleuchtet werden, dann wird gemäß Figur 4 das von der Lichtquelle 2 ausgesandte Licht durch zwischen Lichtquelle 2 und Lichtleitscheibe angeordnete Lichtleitstäbe 8 geleitet, deren Lichtaustrittsseiten 9 konvex, konkav oder abgeschrägt geformt sind. Die Form der Lichtaustrittsseiten 9 der Lichtleitstäbe 8 bestimmt gezielt die Hchtverteilung in der stirnseitig bestrahlten Lichtleit- | scheibe. £ If certain sectors of the light guide disk are to be illuminated in a concentrated, scattered or directional manner, then according to FIG. The shape of the light exit sides 9 of the light guide rods 8 specifically determines the light distribution in the light guide | disc. £
Figur 5 zeigt die Anordnung eines Lichtleitstabes 8 bei einer Standleuchte. Der Lichtleitstab 8 ist in diesem Fall gleichzeitig Teil des Lampenfußes. Lichtquellen 2 befinden sichFigure 5 shows the arrangement of a light guide rod 8 in a Floor lamp. In this case, the light guide rod 8 is also part of the lamp base. Light sources 2 are located

derart verdeckt im Sockel 11 der Standleuchte, daß eine Weiterleitung
von Lichtstrahlen zur Lichtleitscheibe 4 nur mittels
des Lichtleitstabes 8 erfolgen kann. Die Anordnung zusätzlicher Lichtquellen in den Rahmenteilen 1 ist denkbar.so covered in the base 11 of the floor lamp that a forwarding of light rays to the light guide plate 4 only by means
of the light guide rod 8 can be done. The arrangement of additional light sources in the frame parts 1 is conceivable.
Soll die Raumleuchte zur reflektiven Lichtabstrahlung von Fotografien
verwendet werden, dann sind der Leuchte Lichtleitscheiben zuzuordnen, auf welche die Fotografie im fotografischen Verfahren
unmittelbar aufgebracht ist, oder die Lichtleitscheibe
mit der Fotografie mittels lichtleitenden Klebstoffes, beispielsweise Kunstharz, homogen verbunden ist.If the room lamp is to be used for reflective light emission from photographs, then the lamp must be assigned light guide disks to which the photograph is directly applied in the photographic process, or the light guide disk
is homogeneously connected to the photograph by means of light-conducting adhesive, for example synthetic resin.
