Abstract (en)
[origin: EP2073608A1] The system has a group of circuits formed by a central processing unit (10) and an infra red sensor (9) that activates the unit so as to control the change of a state of a switch relay (2) of a space lighting source i.e. incandescent lamp (1). Failure detector units formed by comparators (15-18), low threshold memory (15S), low threshold supply memory (16S) and ambient light level memory (18S), are arranged for detecting type of failure of constituent of the group and for generating a safety, passage or maintenance controls in an ignition state of the source.
