Abstract (en)
[origin: EP2124507A2] The transmitter has a circuit part provided for adjusting a signal transmitter current-operating voltage-characteristic curve of a LED-light signal to a characteristics curve of a filament lamp-light signal. A load is controlled based on the operating voltage, where a resistor network with electronically switchable resistors (R1-R3) is provided as the load. Electronic switches (13.1-13.3) of the resistor network are controlled by a microcontroller (14) based on the operating voltage, and an opening-contact is provided for simulation of switching current surge of the lamp-light signal.
