Abstract

Die Erfindung bezieht sich auf eine LED-Leuchte aus einem Gehäuse, mindestens einer LED als Lichtquelle und einer Linse zum Führen des von der Lichtquelle abgestrahlten Lichts. Um eine LED-Leuchte zu schaffen, die bei erheblich höherer Leistung ohne eine aktive Kühleinrichtung arbeitet, sieht die Erfindung vor, dass das Gehäuse (1) als kegelstumpfförmiger Kühlkörper (2) mit einer Vielzahl in der Außenwand (3) angeordneter Kühlrippen (4) ausgebildet ist, dass eine kegelstumpfförmige Großlinse (10) mit einem im Wesentlichen gleichen Raumvolumen wie der Kühlkörper (2) vorgesehen ist, und mit der im Durchmesser kleinen Fläche (11) der Großlinse (10) an die im Durchmesser große Fläche (13) des Kühlkörpers (2) anschließt, dass zwischen dem Kühlkörper (2) und der Großlinse (10) ein LED-Array (21) mit einer Vielzahl von LEDs angeordnet ist und dass für den Kühlkörper (2) und die Großlinse (10) die jeweils große Fläche (7, 13) umfassende, miteinander verbundene Rahmenteile (14, 15) vorgesehen sind. (Fig. 4)

The invention relates to an LED lamp comprising a housing, at least one LED as a light source and a lens for guiding the light emitted by the light source. In order to provide an LED lamp which operates at significantly higher power without an active cooling device, the invention provides that the housing (1) as a frusto-conical heat sink (2) with a plurality in the outer wall (3) arranged cooling fins (4) in that a frusto - conical large lens (10) with substantially the same volume as the heat sink (2) is provided, and with the small diameter surface (11) of the large lens (10) on the large diameter surface (13) of the Heatsink (2) connects that between the heat sink (2) and the large lens (10) an LED array (21) is arranged with a plurality of LEDs and that for the heat sink (2) and the large lens (10) each large Surface (7, 13) comprising, interconnected frame parts (14, 15) are provided.
