Abstract

Um eine LED-Leuchte zu schaffen, bei der der Abstand zwischen LED (18) und Linse (30) einfach und genau einstellbar ist, ist die LED-Leuchte ausgestattet mit einem rotationssymmetrischen ersten Gehäuseteil (10), das eine LED (18) aufweist, und mit einem rotationssymmetrischen zweiten Gehäuseteil (12), das eine plankonvexe Linse (30) in dem Strahlengang der LED (18) aufweist. Ferner weist die LED-Leuchte eine Drehverstellanordnung aus einer um die Längsachse schraubenlinienförmig verlaufenden Führungsnut (22) an dem einen der beiden Gehäuseteile (10,12) auf sowie einen in der Führungsnut (22) geführten Zapfen (24) an dem anderen der beiden Gehäuseteile (10,12), so dass durch Verdrehen der beiden Gehäuseteile (10,12) gegeneinander der Abstand zwischen der Linse (30) und der LED (18) in axialer Richtung verstellbar ist, wobei der Winkel (α) zwischen der Schraubenlinie und der Längsachse (14) in der Draufsicht zwischen 20° und 80° beträgt.

In order to provide an LED lamp in which the distance between the LED (18) and lens (30) is easily and accurately adjustable, the LED lamp is equipped with a rotationally symmetrical first housing part (10) having an LED (18) , and with a rotationally symmetrical second housing part (12) having a plano-convex lens (30) in the beam path of the LED (18). Furthermore, the LED lamp has a Drehverstellanordnung from a helical to the longitudinal axis extending guide groove (22) on one of the two housing parts (10,12) and a guided in the guide groove (22) pin (24) on the other of the two housing parts (10,12), so that by rotating the two housing parts (10,12) against each other, the distance between the lens (30) and the LED (18) is adjustable in the axial direction, wherein the angle (α) between the helix and the Longitudinal axis (14) in the plan view between 20 ° and 80 °.
