Abstract
Description
Die Erfindung betrifft eine Leuchtanordnung, spezieller eine Leuchtanordnung für einen Bildprojektor.The The invention relates to a lighting arrangement, more particularly to a lighting arrangement for one Image projector.
Ein herkömmlicher Bildprojektor weist eine Glühlampe und eine Mehrzahl von Lüftungselementen zum Ableiten der von der Glühlampe erzeugten Wärme auf.One conventional Image projector has a light bulb and a plurality of ventilation elements for deriving the from the light bulb generated heat on.
Der vorstehend erwähnte herkömmliche Bildprojektor ist insofern nachteilig, als die Lüftungselemente relativ viel Platz in dem herkömmlichen Bildprojektor einnehmen, woraus ein größeres Außenmaß für den herkömmlichen Bildprojektor resultiert.Of the mentioned above conventional image projector is disadvantageous in that the ventilation elements relatively much Place in the conventional picture projector take a larger external dimension for the conventional Image projector results.
Daher besteht die Aufgabe der vorliegenden Erfindung darin, eine Leuchtanordnung für einen Bildprojektor zur Verfügung zu stellen, welche den mit dem Stand der Technik verbundenen Nachteil beheben kann.Therefore the object of the present invention is a luminous arrangement for an image projector to disposal to provide which the associated with the prior art disadvantage can fix.
Entsprechend der vorliegenden Erfindung umfasst eine Leuchtanordnung für einen Bildprojektor ein Wärmeableitungselement, eine lichtemittierende Einrichtung und einen Reflektor. Das Wärmeableitungselement weist eine wärmeleitende Grundfläche, eine wärmeleitende Umfangswand und eine Mehrzahl von wärmeleitenden Rippen auf. Die wärmeleitende Umfangswand erstreckt sich von der wärmeleitenden Grundfläche aus und bestimmt zusammenwirkend mit der wärmeleitenden Grundfläche einen Aufnahmeraum. Die wärmeleitenden Rippen sind außerhalb des Aufnahmeraums angeordnet und sind an der wärmeleitenden Umfangswand ausgebildet. Die lichtemittierende Einrichtung ist in dem Aufnahmeraum angeordnet. Der Reflektor dient dazu, das von der lichtemittierenden Einrichtung abgestrahlte Licht zu reflektieren, er erstreckt sich in den Aufnahmeraum hinein und umgibt die lichtemittierende Einrichtung.Corresponding The present invention comprises a lighting arrangement for a Image projector a heat dissipation element, a light-emitting device and a reflector. The heat dissipation element has a heat-conducting Floor space, a thermally conductive Circumferential wall and a plurality of thermally conductive ribs. The thermally conductive Circumferential wall extends from the heat-conducting base and determines cooperatively with the heat conductive base Recording room. The thermally conductive Ribs are outside arranged in the receiving space and are formed on the heat-conductive peripheral wall. The light-emitting device is arranged in the receiving space. The reflector serves that of the light-emitting device it reflects into radiated light, it extends into the receiving space into and surrounds the light-emitting device.
