Description
Die vorliegende Erfindung betrifft im Allgemeinen Leuchtdioden und insbesondere eine Gehäusestruktur für einen Hochleistungs-Leuchtdioden-Chip und ein zugehöriges Herstellungsverfahren davon.The The present invention relates generally to LEDs, and more particularly a housing structure for a high performance light emitting diode chip and an associated manufacturing method thereof.
Energische Forschungsaktivitäten sind in den letzten Jahren auf Hochleistungs-Leuchtdioden (LEDs) in den entsprechenden Industrien konzentriert worden. Einer der wichtigsten Gesichtspunkte für die Unterbringung eines Hochleistungs-LED-Chips handelt von der angemessenen Handhabung der hohen Temperatur und der Wärme, die durch den Hochleistungs-LED-Chip erzeugt werden, so dass die Funktionalität, die Leistungsfähigkeit und die operative Lebensdauer des LED-Chips nicht gefährdet sind.energetic Research activities have been focused on high-performance light-emitting diodes (LEDs) in recent years been concentrated in the relevant industries. One of main considerations for housing a High-performance LED chips is about the appropriate handling the high temperature and the heat passing through the high power LED chip be generated, so that the functionality, the performance and the operating life of the LED chip is not compromised are.

Gehäusestruktur, die durch das
Dementsprechend ist das Hauptziel der vorliegenden Erfindung, eine Gehäusestruktur, welche zum einen eine ausgezeichnete Wärmeableitungseffizienz erzielt, und ein zugehöriges Fertigungsverfahren zum Unterbringen eines Hochleistungs-LED-Chips vorzusehen, welches zum anderen in der Massenproduktion bei erheblich geringeren Produktionskosten verwendbar ist.Accordingly the main object of the present invention is to provide a housing structure, which on the one hand an excellent heat dissipation efficiency achieved, and an associated manufacturing method for housing a high-power LED chip, which on the other in mass production at significantly lower production costs is usable.
Die durch die vorliegende Erfindung vorgesehene Gehäusestruktur weist hauptsächlich eine Basis, eine Reflexionsplatte, den untergebrachten LED-Chip, Bonddrähte zum Verbinden der Elektroden des LED-Chips und einen transparenten Füllstoff oder eine transparente Linse zum Abdichten und Schützen des LED-Chips und der Bonddrähte auf. Die Basis, die einen flachen Formfaktor aufweist, ist aus einem metallischen Material und einem elektrisch isolierenden Material hergestellt, die zu einem einzigen Gegenstand integriert zusammengefügt sind. Das metallische Material bildet einen Wärmesenkensitz in der Mitte der Basis mit ausreichenden Abständen zu den Rändern der Basis aus. Der Wärmesenkensitz ist von der oberen Fläche der Basis und von der unteren Fläche oder einer Seitenfläche der Basis freigelegt. Das metallische Material bildet ferner eine Mehrzahl von Elektroden aus, die den Wärmesenkensitz umgeben. Die Elektroden sind von der oberen Fläche der Basis und von der unteren Fläche oder einer Seitenfläche der Basis freigelegt. Das elektrisch isolierende Material ist zwischen den Elektroden und dem Wärmesenkensitz eingefügt, so dass sie aneinander haften und so dass der Wärmesenkensitz und jeweils eine Elektrode und jeweils zwei Elektroden elektrisch isoliert sind.The housing structure provided by the present invention mainly includes a base, a reflection plate, the accommodated LED chip, bonding wires for connecting the electrodes of the LED chip, and a transparent filler or a transparent lens for sealing and protecting the LED chip and the bonding wires , The base, which has a flat shape factor, is made of a metallic material and an electrically insulating material, which are assembled together into a single article. The metallic material forms a heat sink seat in the middle of the base with sufficient Distances to the edges of the base. The heat sink seat is exposed from the upper surface of the base and from the lower surface or a side surface of the base. The metallic material further forms a plurality of electrodes surrounding the heat sink seat. The electrodes are exposed from the top surface of the base and from the bottom surface or a side surface of the base. The electrically insulating material is interposed between the electrodes and the heat sink seat so as to adhere to each other and so that the heat sink seat and each one electrode and each two electrodes are electrically insulated.
Der untergebrachte LED-Chip ist an die freigelegte obere Fläche des Wärmesenkensitzes angeklebt. Die positiven und negativen Elektroden des LED-Chips sind mit den freigelegten oberen Flächen der entsprechenden Elektroden der Basis separat verbunden. Die Reflexionsplatte ist an der Basis mittels eines geeigneten Mittels fest angebracht, so dass eine vertikale Durchgangsbohrung der Reflexionsplatte den LED-Chip oben auf dem Wärmesenkensitz der Basis freilegt. Das von dem LED-Chip ausgestrahlte Licht ist infolgedessen in der Lage, nach außen zu strahlen. Die Reflexionsplatte ist aus einem metallischen Material, das ein hohes Reflexionsvermögen aufweist, oder aus einem nicht-metallischen Material hergestellt, bei dem die Wand der Durchgangsbohrung mit einem Film oder einer Schicht aus hoch reflektierendem Material beschichtet ist. Der Füllstoff oder die Schutzlinse ist aus einem transparenten Material, wie zum Beispiel Harz, hergestellt und im Inneren der Durchgangsbohrung angeordnet, um den LED-Chip und die Bonddrähte abzudichten und zu schützen.Of the housed LED chip is at the exposed upper surface glued to the heat sink seat. The positive and negative Electrodes of the LED chip are with the exposed upper surfaces of the corresponding electrodes of the base are connected separately. The reflection plate is firmly attached to the base by means of a suitable means, so that a vertical through hole of the reflection plate the LED chip on top of the heat sink seat of the base exposes. The emitted light from the LED chip is consequently in the Able to radiate outward. The reflection plate is made of a metallic material that has a high reflectivity or made of a non-metallic material, in which the wall of the through-hole with a film or a layer made of highly reflective material. The filler or the protective lens is made of a transparent material, such as Example resin, manufactured and inside the through hole arranged to seal the LED chip and the bonding wires and protect.
Die Basis der Gehäusestruktur weist eine vereinfachte Struktur auf und ist folglich für eine Massenproduktion sehr geeignet. Das von der vorliegenden Erfindung vorgesehene Fertigungsverfahren verwendet eine einzelne metallische Platte, um die Basen für eine große Anzahl von Einheiten der Gehäusestruktur gleichzeitig herzustellen. Die Wärmesenkensitze und die Elektroden der Basen sind durch Ätzen der metallischen Platte in einem einzelnen Arbeitsgang oder durch Ätzen der zwei Hauptflächen der metallischen Platte in getrennten Arbeitsgängen ausgebildet. Dann wird das isolierende Material zwischen die Wärmesenkensitze und die Elektroden eingefüllt. Danach wird die Reflexionsplatte an die Basis angeklebt, der LED-Chip wird oben auf dem Wärmesenkensitz befestigt, Bonddrähte werden an die Elektroden des LED-Chips und den freigelegten oberen Flächen der Elektroden der Basis angeschlossen, der Füllstoff wird in die Durchgangsbohrung der Reflexionsplatte gefüllt, und schließlich werden die Einheiten der Gehäusestruktur durch Schneiden getrennt.The Base of the housing structure has a simplified structure and is therefore very suitable for mass production. The method of manufacture provided by the present invention uses a single metallic plate to make the bases for a large number of units of the housing structure at the same time. The heat sink seats and the Electrodes of the bases are made by etching the metallic ones Plate in a single pass or by etching of the two main surfaces of the metallic plate in separate Operations trained. Then the insulating material filled between the heat sink seats and the electrodes. Thereafter, the reflection plate is glued to the base, the LED chip is attached to the top of the heat sink seat, bonding wires are applied to the electrodes of the LED chip and the exposed top surfaces connected to the electrodes of the base, which becomes filler filled in the through hole of the reflection plate, and finally the units become the case structure separated by cutting.
