Method for lamp monitoring in light signalling systems and light signalling system
The method involves detecting a current flowing through at least one light source (12a.., 20a..) or a correlated parameter during an initialization phase, determining and storing a reference value using the detected value, detecting the current etc. in an operating phase and determining a comparison...

| Zusammenfassung: | The method involves detecting a current flowing through at least one light source (12a.., 20a..) or a correlated parameter during an initialization phase, determining and storing a reference value using the detected value, detecting the current etc. in an operating phase and determining a comparison value, comparing the comparison and reference values and evaluating the comparison result. AN Independent claim is also included for the following: a light call system for care applications. |
