Lampelamp

Die Erfindung bezieht eioh auf eine Lampe zum Einspeisen von Licht in eine lichtdurchlässige Platte durch eine schmale Fläche der Platte. The invention relates to a lamp for feeding light into a translucent plate through a narrow area of the plate.

Der Erfindung liegt die Aufgabe zugrunde,diese Lampe derart auszubilden,daß möglichst viel Licht in die Platte gelangt, andererseits aber die Wärmeeinwirkung von der Lampe auf die Platte möglichst gering ist.The invention is based on the object of designing this lamp in such a way that as much light as possible reaches the plate, but on the other hand the heat effect from the lamp on the plate is as low as possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst,daß die Lampe aus einem vorzugsweise zylinderförmigen Gehäuse mit' lichtdurchlässigen Wänden besteht,daß das Gehäuse mit einer Öffnung der Platte vorzugsweise spielfrei steckt,daß sich die Lichtquelle der Lampe ganz oder teilweise zwischen den beiden großen Flächen der Platte befindet und daß die Zylinderwand des Gehäuses mit einer Infrarot-weitgehend undurchlässigen Schicht bedeckt ist.This object is achieved according to the invention in that the lamp consists of a preferably cylindrical housing with translucent walls, that the housing is preferably fitted with no play into an opening in the plate, that the light source of the lamp is located entirely or partially between the two large surfaces of the plate and that the cylindrical wall of the housing is covered with a layer that is largely impermeable to infrared.

Durch die erfindungsgemäße Maßnahme wird nicht nur die Lichteinspeisung besonders günstig gestaltet,es wird darüber hinaus auch, bewirkt,daß die Warmeeinstrahlung gering ist» Hierbei ist zu beachten,daß die Infrarotstrahlen praktisch vollständig an der infrarotreflektierenden Schicht derart reflektiert werden, daß sie schließlich das Gehäuse verlassen,denn mehr oder weniger nie wird ein Infrarotstrahl die infrarotreflektierende Schicht aufgrund von Mehrfachreflektion mehrfach treffen,(Bei jedem Auf treffen wird ein kleiner Teil durchgelassen)The measure according to the invention not only makes the light feed particularly favorable, it also ensures that the heat radiation is low. It should be noted that the infrared rays are practically completely reflected by the infrared-reflecting layer in such a way that they eventually leave the housing, because an infrared ray will more or less never hit the infrared-reflecting layer multiple times due to multiple reflection (a small part is allowed through each time it hits it).

Eine Weiterentwicklung der erfindungsgemäßen Vorrichtung ist in der Sieher9teilung der permanenten Luftkonvektion innerhalb des Gehäuses (5) zu sehtn.Hierzu dienen die unter Anspruch 3 beschriebene Lüftungsöffnung (8) in der Kappe (7) des Gehäuses (5) und die unter Anspruch 4 beschriebenen Lüftungsöffnungen (10) auf der der Kappe (7)gegenüberliegenden Seite.Durch eine derartige Anordnung wird eine zu hohe Erwärmung der im Gehäuse befindlichen Luft durch sichergestellte Kaminwirkung vermieden. Zusätzlich zu dieser Maßnahme könnte es sich als sinnvoll erweisen,den Luftraum zwischen der transparenten Außenwand des Gehäuses (5) und der Infrarot-undurchlässigen Schicht (6) zusätzlich zu belüften.A further development of the device according to the invention can be seen in the division of permanent air convection within the housing (5). The ventilation opening (8) described in claim 3 in the cap (7) of the housing (5) and the ventilation openings (10) described in claim 4 on the side opposite the cap (7) serve this purpose. Such an arrangement prevents the air in the housing from heating up too much by ensuring a chimney effect. In addition to this measure, it could prove useful to additionally ventilate the air space between the transparent outer wall of the housing (5) and the infrared-impermeable layer (6).

Von besonderer Bedeutung ist natürlich die gezielte Lichteinspeisung in die lichtdurchlässige Platte (1).Eine gezielte scheinwerferähnliche Lichtführung innerhalb der Lichtleitplatten erreicht man,indem Teilflächen der lichtdurchlässigen Wände des Gehäuses (5)mit möglichst hochreflektierend-m Material verspiegelt sind.Of particular importance is, of course, the targeted light feed into the translucent plate (1). A targeted spotlight-like light guidance within the light guide plates is achieved by partially covering the translucent walls of the housing (5) with the most highly reflective material possible.

Eine weitere Konzentration des gerichtet eingespeisten Lichtes in die transparenten Platten wird durch Fresnel-linsenförmige Ausformungen von Teilflächen dev lichtdurchlässigen Gehäu3ewand sichergestellt.A further concentration of the directed light into the transparent plates is ensured by Fresnel lens-shaped formations of partial surfaces of the translucent housing wall.

Auf die vorbeschriebene Weise lassen sich sowohl Scheinwerferähnliche als auch Spaltlicht-ähnliche Effekte erzeugen. Ebenfalls eine Weiterentwicklung der erfindungsgemäßen Vorrichtung ist in der Teilflächenverspiegelung des die Lichtquelle (4)uisgebenen Glasmantels (3)su sehen,derart,daS der von. der Lichtquelle (4) ausgesandte Lichtstrom bereits in unmittelbarer Nähe der Lichtquelle zut den lichtdurchläs sigen Wänden, des .Ge-In the manner described above, both spotlight-like and slit-light-like effects can be produced. Another further development of the device according to the invention can be seen in the partial surface mirroring of the glass jacket (3) surrounding the light source (4), such that the luminous flux emitted by the light source (4) is already reflected in the immediate vicinity of the light source to the translucent walls of the housing.

Weiterhin ist es sinnvoll,zur Verstärkung der gezielten richtungsorientierten Lichteinspeisung in die lichtdurchlässige Platte eine Lichtquelle mit innerhalb des die Lichtquelle umgebenden Glasmantels angeordneten Reflektorschirm zu verwenden.Furthermore, it is useful to use a light source with a reflector screen arranged inside the glass jacket surrounding the light source to enhance the targeted, direction-oriented light feed into the translucent plate.

Weitere Einzelheiten der Erfindung ergeben sich aus der einzigen Figur der Zeichnung.Darin ist mit(1) eine (durchsichtige)Acrylglasplatte und mit (2)eine in dieser steckenden Lampe bezeichnet.Letztere besteht aus der glasummantelten Leuchte(3)mit Wendel(4)als Lichtquelle und einem zylinderförmigen Gehäuse(5)mit teilweise lichtdurchlässigen Außenwänden. Das Gehäuse steckt weitgehend spielfrei in der Platte (1).Auf seiner Innenseite weist das Gehäuse eine infrarot, weitgehend undurchlässige Schicht (6)auf.Ferner ist die Lampe mit einer Kappe(7)versehen,die Lüftungsschlitze (8)besitzt. Im,der Kappe (7)gegenüberliegenden Gehäuseteil sind ebenfalls Lüftungsschlitze (10)angeordnet.Auf der Unterseite der Platte (1)befindet sich eine Schicht(9),die eine apfelsinenschalenförmige AuBenseite besitzt.Auf diese Weise wird erreicht,daß das Licht,welches sich in der Platte(1) befindet,in Eezug auf die Figur mehr öder weniger gleichmäßig über die Fläche (9) verteilt,austritt.Further details of the invention can be seen from the single figure in the drawing. In it, (1) is a (transparent) acrylic glass plate and (2) is a lamp inserted into it. The latter consists of the glass-coated lamp (3) with a coil (4) as a light source and a cylindrical housing (5) with partially translucent outer walls. The housing is inserted into the plate (1) with almost no play. On its inside, the housing has an infrared, largely impermeable layer (6). The lamp is also provided with a cap (7) that has ventilation slots (8). Ventilation slots (10) are also arranged in the housing part opposite the cap (7). On the underside of the plate (1) there is a layer (9) which has an orange peel-shaped outside. In this way it is ensured that the light which is in the plate (1) emerges more or less evenly distributed over the surface (9) in relation to the figure.
