Description
Die Erfindung betrifft eine Beleuchtungseinrichtung gemäß dem Oberbegriff des Anspruchs 1. The invention relates to a lighting device according to the preamble of claim 1.
I. Stand der TechnikI. State of the art
Eine derartige Beleuchtungseinrichtung ist beispielsweise in der
II. Darstellung der ErfindungII. Presentation of the invention
Es ist Aufgabe der Erfindung, eine gattungsgemäße Beleuchtungseinrichtung bereitzustellen, die auf einfache Weise die Erzeugung unterschiedlicher Lichtverteilungen ermöglicht und die außerdem eine einfache elektrische Kontaktierung und Kühlung ihrer Halbleiterlichtquellenanordnungen erlaubt. It is an object of the invention to provide a generic lighting device that allows the generation of different light distributions in a simple manner and also allows easy electrical contacting and cooling of their semiconductor light source arrangements.
Diese Aufgabe wird erfindungsgemäß durch eine Beleuchtungseinrichtung mit den Merkmalen aus dem Anspruch 1 gelöst. Besonders vorteilhafte Ausführungen der Erfindung sind in den abhängigen Ansprüchen beschrieben. This object is achieved by a lighting device with the features of claim 1. Particularly advantageous embodiments of the invention are described in the dependent claims.
Die erfindungsgemäße Beleuchtungseinrichtung besitzt mindestens zwei, auf einer Wärmesenke montierte Halbleiterlichtquellenanordnungen, wobei die mindestens zwei Halbleiterlichtquellenanordnungen erfindungsgemäß auf unterschiedlichen Stufen mindestens eines stufenartigen Abschnitts der Wärmesenke angeordnet sind und zur elektrischen Kontaktierung der mindestens zwei Halbleiterlichtquellenanordnungen ein abgestufter Leiterrahmen vorgesehen ist. The illumination device according to the invention has at least two semiconductor light source arrangements mounted on a heat sink, wherein the at least two semiconductor light source arrangements are arranged on different stages of at least one step-like portion of the heat sink and a graduated lead frame is provided for electrical contacting of the at least two semiconductor light source arrangements.
Durch die Montage der mindestens zwei Halbleiterlichtquellenanordnungen auf unterschiedlichen Stufen des mindestens einen stufenartigen Abschnitts der Wärmesenke können die auf den unterschiedlichen Stufen angeordneten Halbleiterlichtquellenanordnungen für unterschiedliche Beleuchtungsfunktionen genutzt werden. Dabei ist es beispielsweise möglich, die Stufe bzw. die Stufen des mindestens einen stufenartigen Abschnitts der Wärmesenke als optische Blende zu verwenden, um gegebenenfalls unter Mitwirkung weiterer optischer Mittel eine scharfe Hell-Dunkel-Grenze zu definieren. Insbesondere kann der mindestens eine stufenartige Abschnitt der Wärmesenke genutzt werden, um die Halbleiterlichtquellenanordnungen gegenüber dem Licht abzuschatten, das von den auf anderen Stufen montierten Halbleiterlichtquellenanordnungen emittiert wird. Der mindestens eine stufenartige Abschnitt der Wärmesenke bietet den weiteren Vorteil, dass alle Halbleiterlichtquellenanordnungen auf einer gemeinsamen Wärmesenke montiert werden können und somit eine einzige Wärmesenke zur Kühlung aller Halbleiterlichtquellenanordnungen verwendet werden kann. Dadurch ist außerdem eine exakte räumliche Ausrichtung dieser Halbleiterlichtquellenanordnungen zueinander möglich. By mounting the at least two semiconductor light source arrangements on different stages of the at least one step-like portion of the heat sink, the semiconductor light source arrangements arranged on the different stages can be used for different illumination functions. In this case, it is possible, for example, to use the step or the steps of the at least one step-like section of the heat sink as an optical stop in order, if appropriate, to define a sharp cut-off line with the assistance of further optical means. In particular, the at least one step-like portion of the heat sink may be utilized to shade the semiconductor light source assemblies from the light emitted by the semiconductor light source assemblies mounted on other stages. The at least one step-like portion of the heat sink offers the further advantage that all semiconductor light source arrangements can be mounted on a common heat sink and thus a single heat sink can be used to cool all semiconductor light source arrangements. As a result, an exact spatial alignment of these semiconductor light source arrangements relative to each other is also possible.
Der abgestufte Leiterrahmen der erfindungsgemäßen Beleuchtungseinrichtung weist vorteilhafterweise metallische Stege auf, die teilweise oder ganz in elektrisch isolierendem Kunststoff eingebettet sind. Die metallischen Stege dienen vorzugsweise als elektrische Verbindung zwischen den Halbleiterlichtquellenanordnungen und Komponenten ihrer Betriebsvorrichtung, insbesondere einer Elektronik zum Betrieb dieser Halbleiterlichtquellenanordnungen. Die Struktur der metallischen Stege ist daher in erster Linie durch die erforderlichen Leiterbahnen bestimmt. Zusätzlich kann der abgestufte Leiterrahmen aber auch frei liegende, nicht im Kunststoffmaterial eingebettete Stege oder Flächen besitzen, die als Kühlrippen oder Kühlflächen bzw. Kühlbleche ausgebildet sind, um die von der Elektronik bzw. die von den Halbleiterlichtquellenanordnungen generierte Wärme an die Umgebung abzuführen. Der abgestufte Leiterrahmen liegt vorzugsweise auf der Wärmesenke auf, um die Kühlwirkung zu erhöhen bzw. um Wärme über die metallischen Stege des abgestuften Leiterrahmens und die Wärmesenke an die Umgebung abzuführen. Im Fall einer metallischen Wärmesenke kann diese beispielsweise mittels einer Kontaktfläche des abgestuften Leiterrahmens an das schaltungsinterne Massebezugspotenzial der Elektronik angeschlossen sein, um die Handhabungssicherheit oder elektromagnetische Verträglichkeit der Beleuchtungseinrichtung zu verbessern. Die metallischen Stege des abgestuften Leiterrahmens verleihen der erfindungsgemäßen Beleuchtungseinrichtung außerdem eine erhöhte Stabilität im Vergleich zu einer üblicherweise für die elektrische Kontaktierung verwendeten Montageplatine.The graduated lead frame of the illumination device according to the invention advantageously has metallic webs which are partially or completely embedded in electrically insulating plastic. The metallic webs are preferably used as electrical connection between the semiconductor light source arrangements and components of their operating device, in particular electronics for operating these semiconductor light source arrangements. The structure of the metallic webs is therefore determined primarily by the required interconnects. In addition, however, the stepped leadframe may also have exposed webs or surfaces not embedded in the plastic material, which are designed as cooling ribs or cooling surfaces or cooling plates in order to dissipate the heat generated by the electronics or by the semiconductor light source arrangements to the environment. The stepped leadframe preferably rests on the heat sink to enhance the cooling effect or to dissipate heat to the environment via the metallic lands of the stepped leadframe and the heat sink. In the case of a metallic heat sink, for example, this can be connected to the circuit-internal ground reference potential of the electronics by means of a contact surface of the stepped leadframe in order to improve the handling reliability or electromagnetic compatibility of the illumination device. The metallic webs of the stepped leadframe also give the illumination device according to the invention an increased stability compared to a mounting board commonly used for electrical contacting.
Vorzugsweise besitzt der abgestufte Leiterrahmen an seiner Oberfläche angeordnete Kontaktflächen, die durch seine metallischen Stege miteinander verbunden sind. Diese Kontaktflächen erlauben eine einfache elektrische Kontaktierung der auf der Wärmesenke montierten Halbleiterlichtquellenanordnungen mittels Bonddrähten sowie eine einfach Montage der Elektronik zum Betrieb der Halbleiterlichtquellenanordnungen. Die räumliche Anordnung und Festlegung der Bauhöhe der Kontaktflächen kann mittels der Spritzgusstechnik sehr präzise vorgenommen werden. Der abgestufte Leiterrahmen bietet daher eine einfache und kostengünstige Alternative zu auf unterschiedlichen Niveaus angeordneten Montageplatinen.The stepped leadframe preferably has contact surfaces arranged on its surface, which are connected to one another by its metallic webs. These contact surfaces allow a simple electrical contacting of the mounted on the heat sink semiconductor light source assemblies by means of bonding wires and a simple mounting of the electronics for operating the semiconductor light source assemblies. The spatial arrangement and determination of the height of the contact surfaces can be made very precisely by means of injection molding. The stepped leadframe therefore provides a simple and cost effective alternative to mounting boards arranged at different levels.
Die erfindungsgemäße Beleuchtungseinrichtung weist vorzugsweise elektronische Komponenten einer zum Betrieb der Halbleiterlichtquellenanordnungen dienenden Elektronik auf, die über den abgestuften Leiterrahmen mit den mindestens zwei Halbleiterlichtquellenanordnungen elektrisch verbunden sind, um eine Platz sparende Anordnung der Elektronik und der mindestens zwei Halbleiterlichtquellenanordnungen zu ermöglichen. Die Komponenten der Betriebsvorrichtung bzw. der Elektronik können beispielsweise unmittelbar auf Kontaktflächen des abgestuften Leiterrahmens gelötet oder geschweißt sein. Besonders stark thermisch belastete Komponenten der Elektronik sind vorzugsweise auf der Wärmesenke montiert oder in einer Aussparung der Wärmesenke angeordnet und mittels Wärme leitender Paste an die Wärmesenke gekoppelt, um eine ausreichende Kühlung dieser thermisch stark belasteten Komponenten zu gewährleisten. Zu ihrer elektrischen Kontaktierung sind die thermisch besonders stark belasteten Komponenten der Elektronik ebenfalls mit Kontaktflächen des abgestuften Leiterrahmens verlötet oder verschweißt. The illumination device according to the invention preferably has electronic components of an electronics serving to operate the semiconductor light source arrangements, which are electrically connected via the stepped leadframe to the at least two semiconductor light source arrangements in order to enable a space-saving arrangement of the electronics and the at least two semiconductor light source arrangements. The components of the operating device or the electronics can for example be soldered or welded directly to contact surfaces of the stepped leadframe. Particularly heavily thermally loaded components of the electronics are preferably mounted on the heat sink or arranged in a recess of the heat sink and coupled by means of heat conductive paste to the heat sink to ensure adequate cooling of these thermally heavily loaded components. For their electrical contacting the thermally particularly heavily loaded components of the electronics are also soldered or welded to contact surfaces of the stepped lead frame.
