SubscribeATG Airports Ltd announced that a recent installation of new LED Technology at Cartagena Airport (Colombia) can reduce the power consumption up to 10%.
ATG Airports (Products) Ltd are pleased to announce that a recent installation in Columbia that combines new LED technology and a simplified electrical infrastructure has reduced the power consumption to 10%, when compared with an equivalent tungsten halogen AGL system.
LED Technology
This installation at Cartagena Airport has 80, ZA216L FAA approved L-861T taxiway edge fittings that are driven directly from a 10-watt series ground-isolating transformer on the 6.6 amp primary loop circuit. The AGL transformer secondary current is stepped down to the maximum rated current for the Blue edge fitting. The 3 watt LED Technology cluster and bridge rectifier incorporated into the lamp housing removes the need for any interfacing electronics.
For this AGL installation, the customer only required two Stages of brilliancy, 100% and 30%. As the current response for a LED fitting is linear, these stages of brilliancy was by operating the L829 constant current regulator at 6.6 amps and 2.6 amps.
LED Ground Transformers
Prior to the installation in Columbia, a total of 80 taxiway edge lights, ZA216LED, and the 10 watt LED ground transformers were tested in Ohio. FAA personnel were invited to participate to witness the benefits of the system. The electrical and photometry characteristics of the systems were monitored to confirm compliance of the simplified system with the additional requirements of Engineering Brief No.67 that are required for the approval of LED airfield ground lights in the United States.
The tests proved that the total number of ZA216LED fixtures only consumed 500 watts at the output of the CCR, compared with 5000 watts that would have been required with Tungsten Halogen lamp type products. Also, the power factor and harmonic content was much improved when LED's where operated in this fashion.
AGL LED System
A full description of the tests and benefits of the simplified AGL LED System were also presented to the Illumination Engineering Society of North America and received critical acclaim and the paper was awarded an 'Honourable Mention'.
ATG airports look forward to providing its customers with the benefits of real power savings and improvements in the life that are realised with LED technology and a simplified electrical installation.
ATG airports with its new breed of sinusoidal constant current regulators, the Micro 200, which is able to deliver power across a wider current range will be well placed in the future to deliver power savings to its customers, as the simplified electrical infrastructure gains mass adoption by the Airfield market.
