OCEM LED test installation achieves remarkable savings in power consumption compared to halogen

year 2016


The company published the findings of a computer simulation and field test in a white paper this month

By optimizing CCR current levels, airports can increase the savings in power consumption offered by LED lighting signals, OCEM Airfield Technology recently demonstrated in computer simulations and on-site field tests.

The findings, which were published this month in a new white paper, (download here) emerged during an experimental set-up at Milan Malpensa Airport in collaboration with SEA, the company that manages Milan’s airports.

For the installation OCEM adapted its taxiway lights to work in the range of 0.9 – 2.2 A, with a 5-step brilliancy control based on the current levels. Step-up transformers were employed for isolation, with a turns ratio of 1:3, in order to increase the voltage and decrease the current in the secondary circuits.

A taxiway comprised of 20 mono- and bi-directional lights was then supplied with reduced currents along the secondary circuit.

Computer simulations projected significant savings compared to halogen lighting signals. 

In the spring, SEA began measuring data to evaluate the benefits of new levels for power supply. The field measurements confirmed the simulated findings.

The findings make it clear that with adjustments to the current and brilliancy voltage, airports can unlock the huge savings potential of LED while still satisfying existing AGL regulations and standards.
