Zusammenfassung:	The invention relates to a multiflap shutter for lighting devices, especially spotlights, comprising a number of lamellae (4) which are mounted inside a frame in a fixed or rotatable manner, and which are made of a non-ceramic supporting material (40) and of a ceramic material (41) that surrounds the supporting material (40) in an all-round manner. Said ceramic material has light-absorbing properties and optionally contains additional heat-resisting particles (42). The surface of the lamellae (4) is, in particular, black or is provided with a color that is similar to that of anthracite.
