Abstract (en)
[origin: EP1035754A2] The device has a light emitting diode and a control unit that controls its operating current. The control unit repeatedly and temporarily raises the light emitting diode's operating current (IN) above the usual level of the operating current in order to increase the signaling effect of the warning.
