Abstract

A LED illumination module has at least one LED ( 6 ). At a proximal side there is a first electric connection contact ( 8 ) and at an axially oppositely directed distal side there is a second electrical connection contact ( 10 ) as well as a radiation region emitting radiation. The LED ( 6 ), at the second electrical connection contact ( 10 ), is contacted via an electrically conductive sleeve ( 14 ) which, distanced to the proximal end, is electrically conductively connected to the second connection contact ( 10 ) of the LED ( 6 ).
