Abstract

A connection element electrically connects an LED light module. The LED light module has a printed circuit board with contact springs for the electrical supply of the LED. The connection element includes an annular frame to cover the printed circuit board and to hold it mechanically on an arrangement surface of a counter bearing. A contact arrangement is mounted in the frame and serves to supply the LEDs with electricity. The frame is divided into an outer ring and an inner ring. The outer ring is provided to surround the printed circuit board and to hold it in the parallel direction to the arrangement surface of the counter bearing. The inner ring at least regionally surrounds the printed circuit board and is provided to hold the printed circuit board in the vertical direction to the surface of the counter bearing. The inner ring is implemented in a light directing component.
