SYSTEMS AND METHODS FOR HEATER CONTROL BY CURRENT LEVEL STEP DETECTION

摘要

An airfield lighting system can comprise a control system, a constant current regulator, and a plurality of light fixtures. The control system can command the constant current regulator to output a current level transition sequence. One or more light fixtures of the plurality of light fixtures can detect the current level transition sequence and execute a command at the light fixture, such as actuating a heating element or adjusting the intensity of light emitted by a light source.
