Abstract
Ein einstückiger LED-bestückter Leuchtenmodul (11) wird ohne nachträgliche Justageerfordernisse einsatzfertig im Mehrkomponenten-Spritzguß gewonnen, indem die LED (13) mit ihrer Bedrahtung von einer wärmebeständigen Trägerplatte (15) umspritzt wird, die einen Kunststoff-Kühlkörper (18) trägt und an die eine optische Bank (19) mit Umlenk-Hohlspiegel (23), Shutter-Blende (25) und gegebenenfalls Halterung (28) für eine Projektions-Linse (27), vorzugsweise schon mit integrierter Linse (27), angegossen wird.A one-piece LED-equipped luminaire module (11) is obtained without subsequent adjustment requirements ready for use in multi-component injection molding by the LED (13) is over-molded with their wiring of a heat-resistant support plate (15) carrying a plastic heat sink (18) and to an optical bench (19) with deflecting concave mirror (23), shutter aperture (25) and possibly holder (28) for a projection lens (27), preferably already with integrated lens (27), is cast.
Description
Als
Leuchtmittel in Leuchten wie Scheinwerfern einsetzbare helle lichtemittierende
Halbleiterdioden (sog. Power-LEDs) strahlen zwar kaum Wärme ab,
erzeugen aufgrund ihres relativ hohen Betriebsstromes aber erhebliche
Verlustwärme, die zum Vermeiden einer Selbstzerstörung über
Wärmeleitung zu Kühlkörpern als Wärmesenken
von der jeweiligen LED abgeleitet werden muß. Die fast
hemisphärisch, über 180° räumlich
sich erstreckende Abstrahlcharakteristik einer LED wird gewöhnlich über
eine reflektive Optik auf einen nutzungsgerechten Strahlengang gebündelt.
Wenn der bestimmte Ausleuchtgeometrie erbringen soll, wie im Falle
der Hell-Dunkel-Grenze des Abblendlichtes eines Kraftfahrzeugscheinwerfers,
dann muß in den Lichtkegel eine geometrisch definiert begrenzte
Blende (der sog. Shutter) hineinragen (vgl.
Häufig
ist eine Leuchte (ähnlich
In Erkenntnis dieser Gegebenheiten liegt vorliegender Erfindung die technische Aufgabenstellung zugrunde, solche mit LEDs bestückten Leuchtenmodule mit gesteigerter Präzision bei vergrößerter Standzeit wirtschaftlicher herzustellen.In Recognition of these facts is the present invention Technical task based, equipped with LEDs Luminaire modules with increased precision when enlarged To make life more economical.
Diese Aufgabe ist erfindungsgemäß gemäß den in den Hauptansprüchen angegebenen wesentlichen Merkmalen gelöst. Danach wird der gesamte Leuchtenmodul mit seiner schon funktionsgerecht justierten elektrischen und optischen Bestückung komplett im Rahmen von Mehrkomponenten-Spritzgußprozessen erstellt.These Task is according to the invention according to the in the main claims specified essential characteristics solved. Thereafter, the entire luminaire module with his already functionally adjusted electrical and optical equipment completely created in the context of multi-component injection molding processes.
Dazu wird in eine Form die gehäuste LED positionsgenau eingelegt (wobei hier, zur Vereinfachung der Darstellung, dieses Leuchtmittel immer nur in der Einzahl benannt wird, wenngleich ein Leuchtenmodul im Rahmen vorliegender Erfindung auch mit einer Mehrzahl elektrisch parallel oder vorzugsweise in Serie zu betreibender LEDs bestückt sein kann). Die so positionierte LED wird von einer Trägerplatte aus wenigstens einer Kunststoffkomponente umspritzt. Die hierfür eingesetzten Kunststoff-Materialien sind wie als solches bekannt funktionsspezifisch, insbesondere für niedrige temperaturabhängige Ausdehnung, hohe Standzeit auch unter starker Erwärmung und gute Wärmeleitfähigkeit, ausgerüstet.To is inserted in a form the housed LED positionally accurate (Here, for simplicity of illustration, this bulb is always named in the singular, albeit a lighting module in the context of the present invention also with a plurality of electrical be equipped parallel or preferably in series to be operated LEDs can). The thus positioned LED is from a carrier plate molded from at least one plastic component. The one for this used plastic materials are known as such Function-specific, especially for low temperature-dependent Expansion, long service life even under strong warming and good thermal conductivity, equipped.
Zum elektrischen Kontaktieren der LED ist zuvor noch ein Stanzgitter in die Form eingelegt und an möglichst weit aus dem LED-Gehäuse herausragende Kontaktfahnen angeschlossen, das dann mit der LED zusammen umspritzt und damit im Leuchtenmodul mechanisch funktionsgerecht festgelegt wird; oder als Anschlußleitungen werden, unter Anbindung an die LED-Kontaktfahnen, in einem gesonderten Schuß Stränge aus elektrisch gut leitendem Kunststoff in Nuten in der Trägerplatte eingespritzt.To the electrical contacting of the LED is previously still a punched grid inserted into the mold and as far as possible from the LED housing outstanding contact lugs connected, which then with the LED molded together and thus mechanically functional in the luminaire module is determined; or as connecting lines, under Connection to the LED contact lugs, in a separate weft strands made of electrically good conductive plastic in grooves in the carrier plate injected.
Schließlich werden noch ein Kühlkörper (wenn der nicht schon mit Ausbilden der Trägerplatte an diese angeformt wurde) und eine optische Bank an die Trägerplatte angeformt. An letzterer werden dabei die Halterung eines Umlenk-Hohlspiegels und eine Blende für eine gewünschte Lichtverteilung angeformt oder zusätzlich angespritzt. Bedarfsweise wird für eine Projektionsausleuchtung auch noch eine Linsenhalterung, gegebenenfalls mit schon eingespritzter Linse, an der optischen Bank ausgebildet.After all will still be a heat sink (if not already was formed with forming the carrier plate to this) and an optical bench molded to the carrier plate. At The latter will be the holder of a deflection concave mirror and a Shutter formed for a desired light distribution or additionally sprayed. If necessary, for a projection illumination also a lens holder, if necessary with already injected lens, formed on the optical bench.
Vorzugsweise wird der Leuchtenmodul aus wenigstens zwei verschiedenen Kunststoffen gespritzt, deren spezifischen, thermisch bedingten Ausdehnungen sich derart überlagern, dass der thermische Einfluss auf das Gesamtsystem gezielt reduziert bzw. minimiert wird. Das wird insbesondere dadurch erreicht, dass ein Bestandteil des Leuchtenmoduls, z. B. die Tragplatte, mit einem seiner anderen Bestandteile, z. B. dem Reflektor, derart verbunden wird, dass die reversible thermische Ausdehnung des letzteren sich von derjenigen der ersteren subtrahiert; wodurch die Gesamtausdehnung geringer ist, als die jeweiligen Einzelausdehnungen.Preferably the luminaire module is made of at least two different plastics injected, their specific, thermally induced expansions overlap in such a way that the thermal influence on the entire system is selectively reduced or minimized. That will achieved in particular by virtue of the fact that a component of the luminaire module, z. B. the support plate, with one of its other components, for. B. the reflector, is connected such that the reversible thermal Extension of the latter subtracts from that of the former; whereby the total extent is smaller than the respective individual dimensions.
Jedenfalls kann aus dem Spritzgußprozeß schließlich der bereits einsatzfertige da komplett bestückte und nicht mehr nachzujustierende Leuchtenmodul herausfallen. Dieser nach nur wenigen Prozeßschritten aus den Werkzeugpartien gewonnene Mehrkomponenten-Thermoplastspritzgußkörper weist den Vorteil einer unkritischen Toleranzkette mit insbesondere optisch relevanten Komponenten unterschiedlichster Funktionen auf.In any case can from the injection molding process finally the ready to use since completely assembled and not more readjusting luminaire module fall out. This after only shows a few process steps from the tool parts obtained multi-component thermoplastic injection molded body the advantage of a non-critical tolerance chain with in particular optically relevant components of different functions.
Vorteilhafte Weiterbildungen und Alternativen zur erfindungsgemäßen Lösung ergeben sich aus den weiteren Ansprüchen und, auch hinsichtlich deren Vorteilen, aus nachstehender Beschreibung eines bevorzugten Realisierungsbeispiels für einen erfindungsgemäß erstellten Leuchtenmodul, der in der einzigen Figur der Zeichnung vergrößert und auf das Funktionswesentliche abstrahiert sowie nicht ganz maßstabsgerecht im Längsschnitt skizziert ist.Advantageous developments and alternatives to the inventive solution arise from the other claims and, also with regard to their advantages, from the following description of a preferred implementation example of a luminaire module according to the invention, which is enlarged in the single figure of the drawing and abstracted to the functional essentials and not quite to scale outlined in longitudinal section.
