Abstract
An LED module is described with a basemade out of a heat conducting material. An LED element () is arranged in a cavity () of the base. A collimator reflector () is formed by reflective surfaces (). Three of these reflective surfaces () are provided on a plastic insert () received in the cavity (). A further reflective surface () is provided on the base () itself. This surface () has a straight border line (). The collimator reflector () is arranged to reflect light from the LED () so that a cut-off () is formed by the straight border line (). By thus integrating the cut-off, as the most critical optical element, into the base () itself, high accuracy is achieved.
