Abstract (en)
[origin: WO2020048897A1] The invention relates to a method for operating an LED signal transmitter (2) for rail or road traffic, in which measured values of at least one operating parameter of an LED light source (4) of the LED signal transmitter (2) are recorded and evaluated. In order to be able to better plan maintenance of the LED signal transmitter (2), there is provision according to the invention for a future failure time of the LED signal transmitter (2) to be forecast taking into account the measured values of the at least one operating parameter. The invention furthermore relates to an LED signal transmitter (2) for rail or road traffic and to a traffic system.
