Abstract:

An airport strobe lighting system includes a BCD source of pulses generating trigger voltages for a plurality of strobe lamps and a sensor circuit for comparing confirmation signals with the trigger pulses and generating corresponding return pulses indicative of the operation of the strobe lamps. A microcontroller is supplied with conditioned 5 bit address inputs from the BCD source of pulses and conditioned confirmation signal outputs from the sensor circuit and compares each confirmation signal with the 5 bit address of the corresponding strobe lamp. The microcontroller controls the illumination of dedicated LEDs to indicate the status of each of the strobe lamps.
