Arrangement comprising electrical elements

摘要

The invention relates to an arrangement which comprises electrical elements which include sensors for electromagnetic radiation such as light or X-rays or are constructed so as to emit or change light. At least one element of the arrangement is provided with a switching unit which evaluates the signal patterns of at least two control inputs of the element and compares them with at least one activation pattern. The element is activated in the case of correspondence. At least two elements of the arrangement have at least one identical activation pattern. The control inputs of the elements are preferably coupled to a control lead bus.
