Abstract (en)
[origin: WO2016050521A1] The invention relates to an apparatus for monitoring a signal transmitter for a traffic control signal installation, which signal transmitter comprises a light-emitting diode, said apparatus comprising: a two-channel measuring device for measuring an actual light intensity of the light which is emitted by means of the diode and for measuring at least one electrical characteristic variable of the diode, and a control device for operating the signal transmitter depending on the measured actual light intensity and the measured electrical characteristic variable. The invention further relates to a corresponding method, to a signal transmitter, to a traffic control signal installation and to a computer program.
