Abstract
A warning light is provided for optically displaying at least one and preferably a number of different operating states, of a technical device such as a machine, an installation, a vehicle or the like. The warning light has at least one luminous element for emitting a sequence of illumination pulses within a specific time interval for the display of a specific operating state, in which the illumination characteristic of the illumination pulses are determined by at least one illumination parameter (P) such as brightness, illumination duration, frequency, color, direction of emission or the like to substantially improve perception of the optical display especially for a particularly critical operating state. This is achieved according to the invention by providing an aperiodic change in at least one of the illumination parameters (P) in a specific time interval.
