Abstract: A LED module for use in a LED light, preferably a LED retrofit lamp, has a leadframe and one or more LEDs which are electrically and mechanically connected to the leadframe. The LED module has one or more stabilizing sections made from an insulating material which are introduced locally, preferably in a punctiform and/or linear manner, into intermediate spaces of the leadframe in order to fasten sections of the leadframe to one another and, preferably, to space them apart from one another.
