LED RING FOR A MECHATRONIC LOCK SYSTEM
The invention relates to an LED ring or optical waveguide for a mechanical (110) or mechatronic (10) lock system, comprising an actuating means (112, 12), such as an insertion-key receptacle (146) or pivoting handle (12), rotatably supported in a housing (110) or recess (10), and comprising a lock nut (116) or bearing piece (10) that can be screwed to the housing or the recess, a thin wall such a metal door panel of a sheet-metal cabinet or of a sheet-metal housing being arranged therebetween, characterized by a light ring (128, 28) surrounding a flange (126, 26) of the housing (110) or of the recess (10) and having a flexible film (132, 32) arranged between the light ring (128, 28) and the thin wall (142, 42), which flexible film bears light-emitting diodes (LEDs) (130, 30) and transmits the light thereof. Thus, a lock indicator integrated into the actuating means is achieved.
