Abstract

Support plate (8) comprises a central horizontal circular surface (1) for positioning LEDs. The feet of the LEDs contact a circuit board with a vertical bore provided through the support plate to allow the feet to contact solder sites. A circular segment ring (3) joins the circular surface and slopes downwardly. Preferred Features: The support plate is made from a ceramic material. Strip conductors are applied directly on the planar lower side of the support plate.

Description

Die Erfindung betrifft eine Trägerplatte zur Aufbringung von LED's.The The invention relates to a carrier plate for the application of LEDs.

Herkömmliche LED-Lampen haben eine bis mehrere senkrecht montierte Leuchtdioden. Da gängige Leuchtdioden in den Durchmessern von 3 bis 10 mm nur über einen eingeschränkten Abstrahlwinkel verfügen, ergibt sich für solche LED-Lampen nur ein begrenzter Abstrahlwinkel und somit Anwendungsfall.conventional LED lamps have one to several vertically mounted LEDs. As usual LEDs in the diameters of 3 to 10 mm only one restricted Have emission angle, arises for Such LED lamps only a limited beam angle and therefore application.

Ungeachtet des eingeschränkten Abstrahlwinkels der einzelnen Leuchtdioden hat sich die Lichtausbeute der Leuchtdioden zwischenzeitlich wesentlich erhöht, und wird technologisch bedingt weiter zunehmen.regardless of the restricted Beam angle of the individual LEDs has the luminous efficacy the light-emitting diodes meanwhile substantially increased, and becomes technological conditionally continue to increase.

Spezielle Hochleistungsleuchtdioden sind durch ihre zusätzliche Kühlanforderung für den Massenmarkt zur substitution herkömmlicher Glühfadenbirnen nur bedingt verwendbar.Specific High power light emitting diodes are due to their additional cooling requirement for the mass market for substitution of conventional Glühfadenbirnen only conditionally usable.

Die Erfindung nutzt hierbei den Einsatz herkömmlicher Leuchtdioden ohne zusätzlichen direkten Kühlaufwand.The Invention uses the use of conventional light-emitting diodes without additional direct cooling effort.

Die Erfindung nutzt hierzu eine kreisförmige Trägerplatte aus Keramik, die sowohl der winkligen Anordnung der Leuchtdioden, zur Vergrößerung des Abstrahlkegels, dient, andererseits auch, durch den Lösungsweg der Erfindung, durch den planen und grossflächigen Kontakt der Leuchtdioden mit der Oberfläche der Trägerplatte aus Keramik eine indirekte passive Kühlung der Leuchtdioden erzielt.The For this purpose, the invention uses a circular support plate made of ceramic, the both the angular arrangement of the LEDs, to increase the emission cone, on the other hand, by the approach of the invention, by the plan and large-scale Contact of the LEDs with the surface of the ceramic support plate indirect passive cooling achieved the LEDs.

Dies wird speziell dadurch erzielt, daß die Aussparungsflächen (14') mit den Kreisringflächen (16') immer im Winkel von 90 Grad zueinander stehen (Winkel (13').This is achieved in particular by the fact that the recessed surfaces ( 14 ' ) with the annular surfaces ( 16 ' ) are always at an angle of 90 degrees to each other (angle ( 13 ' ).

Ein weiterer positiver Aspekt dieser Anordnung ist, daß die Füsse (6') der LED's (9') trotz winkliger Abstrahlung der LED's (9') nicht am Austritt aus dem Glaskörper der LED's (9') abgebogen werden können.Another positive aspect of this arrangement is that the feet ( 6 ' ) of the LEDs ( 9 ' ) despite angular radiation of the LEDs ( 9 ' ) not at the exit from the glass body of the LED's ( 9 ' ) can be bent.

Die Abbiegung der Füsse (6') der LED's (9') in den Abstrahlwinkel (4 bzw. 10') erfolgt erst am Ende der Aussparungen (11'), am Beginn der Bohrungen (12').The turn of the feet ( 6 ' ) of the LEDs ( 9 ' ) in the radiation angle ( 4 respectively. 10 ' ) takes place only at the end of the recesses ( 11 ' ), at the beginning of the drilling ( 12 ' ).

Ein weiterer nicht unbedeutender Vorteil der Erfindungslösung ergibt sich darin, daß die Füsse (6') der LED's (9') total unter der Glaskuppel der LED's (9') und in der Keramik der Trägerplatte (8) abgedeckt sind. Somit kann auf eine zusätzliche Abdeckung aus Glas verzichtet werden, da ein Benutzer nur mit Glas und Keramik in Kontakt kommen kann.Another not insignificant advantage of the invention solution is that the feet ( 6 ' ) of the LEDs ( 9 ' ) totally under the glass dome of the LED's ( 9 ' ) and in the ceramic of the support plate ( 8th ) are covered. Thus, can be dispensed with an additional cover made of glass, since a user can come into contact only with glass and ceramic.

Dieses dient dann der zusätzlichen Kühlung der LED's (9') durch die Umgebungsluft.This then serves the additional cooling of the LED's ( 9 ' ) by the ambient air.

Sowohl der Abstrahlwinkel (17 + 20') als auch die Leuchtstärke sind abhängig von der Anzahl der LED's (9') als auch von der Anzahl der aufgebrachten Kreissegmentringe (3 + 10'), und sind frei wählbar.Both the radiation angle ( 17 + 20 ' ) as well as the luminosity are dependent on the number of LEDs ( 9 ' ) as well as the number of applied circular segment rings ( 3 + 10 ' ), and are freely selectable.

Ein weiterer Aspekt dem die Erfindung gerecht wird, ist eine für die Massenproduktion unabdingbare automatische Fertigungslösung.One Another aspect of the invention, is one for mass production indispensable automatic manufacturing solution.

Die LED'S (9') können senkrecht in die Trägerplatte (8) bestückt werden, und erst danach mechanisch in ihre endgültige Ausgangslage verbracht werden.The LEDs ( 9 ' ) can be placed vertically in the carrier plate ( 8th ), and only then mechanically brought into their final starting position.

Die Bauweise der Trägerplatte (8) ermöglicht ferner eine so kompakte Bauweise, daß eine direkte Substitution einer Glühfadenbirne gegeben ist.The construction of the carrier plate ( 8th ) also allows such a compact design that a direct substitution of a filament bulb is given.
