Warning light for the visual display of at least one operating status

摘要

The warning lamp has illuminating elements designed as multicolor LEDs (2). The illuminating elements are provided for sending a sequence of light impulses within certain time interval during indication of certain operating condition, where the light characteristics of the light impulses is determined by a light parameter (P) such as brightness, luminous period, frequency, color and beam direction. A control unit has a random generator for quasi random aperiodic change of a light parameter and/or a dark parameter of individual illuminating the element in the time interval.
