    摘要： A power supply for LED airfield lighting includes a regulated power supply having a power input, an LED control signal input, and a power output. The power input is configured to be connected to a power source, the LED control signal input is configured to receive an LED control signal, the power output is configured to supply an LED drive current to one or more of the LEDs, and the regulated power supply configured to adjust the LED drive current based upon the LED control signal. The regulated power supply also includes a processor having a current sense input and an LED control signal output connected to the LED control signal input of the regulated power supply. The current sense input is configured to receive a signal corresponding to an airfield current step. The processor is programmed to determine the LED control signal based upon the current sense input signal. The LED control signal is determined so as to enable the LEDs to have a relative intensity approximately equal to relative intensity of an incandescent light source driven at the airfield current step.
