In very few areas of public life does the topic of safety play such a critical role as in air traffic, this is also true in relation to all operations surrounding aircraft on the ground: the aircraft are parked on the airport apron after they have been directed to a spot, here the passengers leave the planes, loading takes place and technical and logistic examinations are undertaken. Uncompromising performance, compliance with all standards, and reliability are the decisive criteria in this context.
Together with Munich Airport, ewo is conducting a model project for energy efficient apron illumination. In this context, LED technology was used instead of the existing high pressure sodium illumination. The LED floodlight F32 is able to illuminate even large areas despite its compact form, it represents the first time that such solutions have been used in such implementations throughout the industry. The dimensions are oriented on proven standards, this allows them to be mounted on existing structures without any problems.
From the lens to the lighting unit to the housing, the F32 was specifically developed by ewo to meet the demands of airports. Areas to be illuminated can thereby be more precisely defined than is possible with conventional technology. The multi-layer concept – involving the overlayering of the consistently distributed light emitted by the individual LED units – ensures that no areas are left in darkness even in the event of a partial failure.
The F-System can be equipped with various optical lenses. Hence, at Munich Airport another special version specifically developed for street lighting ensures optimal illumination of the service road located beyond the apron. In order to enhance the resistance to external influences, such as jet fuel and exhaust fumes, we enclose the lighting technology behind a flat glass cover that also makes it easy to clean.
Light is therefore directed and distributed in a manner that fulfils the requirements of an airport, thereby complying with all of the guidelines and standards for the intensity and consistency of illumination. In relation to safety aspects, the illumination even exceeds the requirements: it can be switched on and off without delay. Since the LEDs used as the source of light have a far higher CRI (Colour Rendering Index), documents, marking and labelling can be read quickly and accurately. In comparison to the orange hue of high pressure sodium lights, this light is perceived to be as much as 25 % brighter.
A high mast with six floodlights of this type now already requires 57 % less energy than was previously the case for a similar level of consistent illumination. The planned integration into a light management system can lead to further savings. With extremely reduced maintenance and over 50,000 hours of life, the LED solution makes an important contribution to saving resources.
