Abstract
A production machine () is proposed, in particular a machine tool or the like, having a machine housing () for at least partially enclosing the production machine () and having an operating state warning light device () for the optical display of at least one operating state of the production machine (), in particular of multiple different operating states, wherein at least one warning light element () is provided, which is implemented as a light-emitting diode () and has a warning light surface, wherein the warning light element () is arranged on a carrier layer, wherein the warning light element () has at least one luminescent layer, which emits a warning light and is arranged between a first and a second electrode, in particular a cathode and an anode, wherein better perceptibility is achieved than in the prior art. This is achieved according to the invention in that the machine housing () at least comprises the warning light element (), and in that the electrode surfaces of the electrodes substantially correspond to the warning light surface of the warning light element (), and in that at least one of the electrodes is light-transmitting and/or transparent.
