At the position of shaft part 401 the second valve piece 200 is clamped between first valve piece 100 and lighting module 300. In the illustrated embodiment the shaft part 401 runs through the centre of the first and second valve piece 100, 200, and the throughflow is controlled by rotating second valve piece 200 relative to first valve piece 100.
