Abstract
Description
Technisches Gebiettechnical area
Die Erfindung betrifft eine Leuchte mit einem in einem Gehäuse angeordneten Leuchtmittel und einer Gehäuseöffnung in einer gewünschten Abstrahlrichtung für das Licht, wobei in der Gehäuseöffnung eine lichtdurchlässige Platte mit einer holographischen Schicht vorgesehen ist, welche für Strahlung in den Bereich der gewünschten Abstrahlrichtungen durchlässig ist.The invention relates to a lamp with one in one case arranged illuminant and a housing opening in a desired Beam direction for the light, with a in the housing opening translucent A plate with a holographic layer is provided, which for radiation in the range of the desired Radiation directions permeable is.
Ziel solcher Anordnungen ist es, den Abstrahlwinkel der Leuchte auf einen vorgegebenen Bereich zu begrenzen um eine Entblendung zu erreichen.The aim of such arrangements is the beam angle of the luminaire towards a given area limit to achieve glare control.
Stand der TechnikState of the art
Die Verwendung von holographischen Schichten zur Entblendung von Leuchten ist aus der WO 02/08799 A2 bereits bekannt. Nachteilig bei diesen Leuchten ist es, daß das Leuchteninnere aus dem nicht entblendeten Winkelbereich zumindest im ausgeschalteten Zustand vollständig einsehbar ist. Weiterhin haben die Leuchten ein inhomogenes Erscheinungsbild gerade aus dem beleuchtbaren Bereich, in welchem sich der Betrachter überwiegend befindet.The use of holographic layers for glare control of lights is already known from WO 02/08799 A2 known. The disadvantage of these lights is that the interior of the lights from the non-glare-free angular range, at least when switched off Condition complete is visible. Furthermore, the lights have an inhomogeneous appearance especially from the illuminable area in which the viewer is predominantly located.
Aus der
Offenbarung der Erfindungepiphany the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Innenleuchte der eingangs genannten Art zu schaffen, bei welcher das Licht in einen Winkelbereich um eine gewünschte Abstrahlrichtung konzentriert wird und bei welcher das Lampeninnere auch aus diesem Winkelbereich nicht einsehbar ist. Weiterhin ist es Aufgabe der Erfindung, eine Leuchte zu schaffen, welche in ausgeschaltetem Zustand ein homogenes Erscheinungsbild aufweist.The invention has for its object a To create interior light of the type mentioned, in which the light is concentrated in an angular range around a desired direction of radiation and in which the lamp interior also from this angular range is not visible. Furthermore, it is an object of the invention to To create luminaire, which when switched off a homogeneous Appearance.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die lichtdurchlässige Platte zusätzlich mit einer teildurchlässigen Schicht bedampft ist. Dadurch wird das Umgebungslicht an der Platte reflektiert. Der Betrachter kann das Lampeninnere auch in dem Winkelbereich nicht mehr einsehen, der von der holographischen Schicht nicht "gesperrt" ist. Durch entsprechende Lackierung des Gehäuses kann weiterhin erreicht werden, daß die Unterseite der Leuchte im ausgeschalteten Zustand ein homogenes Erscheinungsbild aufweist.According to the invention the object is achieved in that the translucent plate additionally with a partially permeable Layer is vaporized. This turns the ambient light on the panel reflected. The viewer can also see the interior of the lamp in the angular range no longer see that is not "blocked" by the holographic layer is. Appropriate painting of the housing can still be achieved be that the Bottom of the lamp when switched off a homogeneous Appearance.
