Abstract

The lamp has an LED light source i.e. LED strip (3) lying outside the lamp, and an optical fiber (1) transporting light energy of the light source into an interior of a refrigerating appliance. The lamp is arranged outside the refrigerating appliance, where received electrical power of the LED light source outside the appliance is outputted as heat into ambient air. An entry point and an exit point cause light deflection in the refrigerating appliance by deformation of the points. The LED strip is connected with a housing (2) in a heat-conducting manner.

Description

Stand der TechnikState of the art

Es ist bekannt, das Innere von Kühlmöbeln durch Leuchten von innen oder von außen zu beleuchten. Die Leuchten sind mit Leuchtstoffröhren oder mit LED-Technik aufgebaut.It is known, the interior of cooling furniture through Lights from the inside or from the outside to illuminate. The lights are with fluorescent tubes or built with LED technology.

Problem:Problem:

Der in Patentanspruch 1 angegebenen Erfindung liegt das Problem des Wärmeeintrags in die Kühlmöbel sowie das Problem der Blendung und/oder der Reflexion an der Verglasung der Kühlmöbel zugrunde. Der Wärmeeintrag in die Kühlmöbel bedingt zusätzliche Energiekosten zur Wärmeabfuhr (Kühleng). Werden Leuchten außerhalb der Verglasung der Kühlmöbel angebracht, so fallen zwar keine zusätzlichen Energiekosten zur Abfuhr des Wärmeeintrags der Leuchte an, jedoch entstehen Blendung und Reflexion an den Glasflächen. Dadurch wird der Kunde beeinträchtigt.Of the specified in claim 1 invention is the problem of heat input in the refrigerated cabinets as well the problem of glare and / or reflection on the glazing the cooling furniture is based. The heat input conditioned in the refrigerated cabinets additional Energy costs for heat removal (Kühleng). Be lights outside the glazing of the refrigerated cabinets, so fall no additional Energy costs to dissipate the heat input the light, but glare and reflection on the glass surfaces. Thereby the customer is affected.

Lösung:Solution:

Dieses Problem wird durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.This Problem is solved by the features listed in claim 1 solved.

Erreichte Vorteile:Achieved benefits:

Die mit der Erfindung erreichten Vorteile bestehen insbesondere darin, daß kein Wärmeeintrag der Beleuchtung in das Innere der Kühlmöbel erfolgt. Die Form des Lichtleiters kann beliebig gewählt werden, um den konstruktiven sowie den designmäßigen Anforderungen der Kühlmöbel zu entsprechen. Durch den Einsatz eines Lichtleiters wird die ausgelegte Ware direkt von innen beleuchtet.The particular advantages of the invention are that no Heat input of Lighting is done in the interior of the refrigerator. The Shape of the light guide can be chosen arbitrarily to the constructive as well as the design requirements to match the refrigerated cabinets. By the use of a light guide, the designed goods directly from illuminated inside.

Somit ist das Problem der Blendung und/oder der Reflektion an den Glasflächen bei außenliegender Beleuchtung gelöst.Consequently is the problem of glare and / or reflection on the glass surfaces at outboard Lighting solved.

Weitere Ausgestaltung der Erfindung:Further embodiment of the invention:

Eine vorteilhafte Erfindung ist im Patentanspruch 2 angeben. Die Anwendung des Patentanspruch 2 bezieht sich auf die Formgebung der Ein- und Austrittsstelle des Lichtleiters. Hiermit kann die Lichtlenkung in den Kühlmöbeln je nach Anforderung bewirkt werden.A advantageous invention is specified in claim 2. The application of claim 2 relates to the shape of the input and Exit point of the light guide. This allows the light control in the refrigerators each be effected as required.

Beschreibung eines Ausführungsbeispiels:Description of an embodiment:

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.One embodiment The invention is illustrated in the drawing and will be described below described in more detail.

Die Zeichnung zeigt die Verglasung Fig. 4 eines Kühlmöbels mit eingesetzter LED-Kaltlichtleuchte im Stoß zweier Verglasungselemente Fig. 4.The drawing shows the glazing Fig. 4 a refrigerated cabinet with inserted LED cold light in the joint of two glazing elements Fig. 4 ,

Es zeigt Fig. 3 den LED-Streifen mit den aufgesetzten LED's (Anmerkung: die Bezeichnung LED steht für Leuchtdioden). Der LED-Streifen (Fig. 3) ist wärmeleitend mit dem Gehäuse Fig. 2 verbunden. Das Gehäuse (Fig. 2) besteht aus einem wärmeleitenden Material, so daß die Wärme der LED's an der Außenseite des Kühlmöbels an die Raumluft abgegeben werden kann. Über dem LED-Streifen (Fig. 3) ist der Lichtleiter Fig. 1 angeordnet. Der Lichtleiter besteht aus lichtleitendem Material. An der Lichtaustrittsfläche Fig. 6 des Lichtleiters wird das Licht Fig. 5 aus den LED's auf die ausgelegte Ware in der Innenseite des Kühlmöbels gestrahlt.It shows Fig. 3 the LED strip with the attached LEDs (note: the designation LED stands for light emitting diodes). The LED strip (Fig. 3 ) is thermally conductive with the housing Fig. 2 connected. The housing (Fig. 2 ) consists of a thermally conductive material, so that the heat of the LED's can be delivered to the outside of the cabinet to the room air. Above the LED strip (Fig. 3 ) is the optical fiber Fig. 1 arranged. The light guide consists of light-conducting material. At the light exit surface Fig. 6 of the light guide, the light Fig. 5 from the LED's on the designed goods in the inside of the cooling unit blasted.

Durch Veränderung der Formgebung der Lichtein- und austrittsstelle des Lichtleiters Fig. 1 kann eine Lichtlenkung innerhalb des Kühlmöbels bewirkt werden.By changing the shape of the light entry and exit point of the light guide Fig. 1 a light deflection within the cabinet can be effected.
