1 LED FLOODLIGHTING LUMINAIRES
1.1
Compliance
The floodlight shall enable for ICAO and FAA compliant illuminations. The manufacturer shall be ISO 9001
and ISO 14001 certified.
The luminaire shall allow an optimal maintenance with reduced recycling and related costs. The floodlight
shall have a minimum lumen output of 40,000 lm.
The efficiency of the floodlight shall be minimum 90 lm/W.
1.2
Certifications
The floodlight shall be CE certified and all components shall be ENEC and UL certified. The floodlight shall
allow the airport to reduce energy consumption and CO 2-emission significantly.
The floodlight shall have a photobiological certificate in compliance with IEC 62471 validating the safety of the
LEDs and shall not be classified higher than “Exempt Risks”.
The floodlight should be RoHS compliant.
1.3
Luminaire
The floodlight luminaire should be made of high quality aluminium with a maximum copper content of 0.5% to
prevent corrosion. The luminaire should be designed for aggressive ambient conditions including salt mist
and high humid environments. The manufacturer shall have test records showing the successful completion
of a 2500 hour salt spray test of the luminaire.
All external screws, bolts, washers etc. shall be of V4A (1.4401) stainless-steel. The bracket shall enable a
stepless tilting of the floodlight.
The floodlight luminaire should have a low profile to minimize the structural load. The luminaire should have a
wind load lower than 0.1 m² at 0° tilting angle.
Optional powder coating of aluminium shall be available for extreme conditions, with 5000 hour salt spray test.
1.4
Tilt Angle
The tilt angle of the luminaire in normal operation should not exceed 15° to avoid light pollution and glare
towards pilots and the ATC tower. The ULR (Upward Light Ratio) value shall be 0.0% eliminating light
pollution and wasted energy costs.
1.5
Ingress Protection
The floodlight shall have a minimum ingress protection rate of IP65. The luminaire shall not require cooling
fins (finned heat sinks) to avoid dirt collection resulting in a reduction of the cooling capacity and reduced life
of the LEDs.
All optical and electronic components shall be protected by a single layer hardened glass cover with a
minimum transmission factor of 95%. The glass cover should be able to be opened without any tools.
All cables inside the floodlight should have two (2) protective layers (double-isolated).
1.6
LED Lighting Units
The floodlight shall be composed of individual replaceable LED lighting units. The optical part shall be made
of high-transparent, non-yellowing PMMA.
In case of partial default the system can be replaced in parts. The replacement of an LED lighting unit shall be
via a plug connection requiring no special tools or on-site wiring.
To enable efficient spare parts management, the LED lighting units shall be interchangeable with the
manufacturer’s other LED lighting products for applications including service roads, parking areas and aprons.
1.7
Built in Redundancy
The floodlight shall be equipped with a multi-layer optical system that ensures equal uniformity at the
reference surface in the event of partial failure of the lighting system. A single LED lighting unit failure shall
never result in a decrease below the uniformity value of 4:1 ratio required by ICAO standards.
The manufacturer shall be able to demonstrate via lighting calculations and false color rendering drawings
that even by turning OFF 50% of the floodlight luminaires, the lighting system still meets the 4:1 uniformity
ratio required by ICAO standards.
1.8
Dimming
The floodlight should be dimmable in the range between 100% and 10% in order reduce the energy
consumption during times of reduced or no airside operation activities. Dimming also results in a higher
lifetime of the floodlight. Dimming shall reduce the intensity of illumination only and shall not decrease the
uniformity below the 4:1 ratio required by ICAO standards.
Each floodlight shall be able to dim left and right individually. Dimming of an aircraft parking stand should not
influence the illumination of adjacent aircraft parking stand in order to ensure a safe airside operation. See
Figure 1 for acceptable dimming and Figure 2 for unacceptable dimming.
1.9
Hot Restrike (Instant On)
In the event of power failure, each floodlight must be at full light output when the power returns. Full light
output power must be reached within one (1) second. No additional equipment shall be required to be
installed such as hot restrike equipment.
1.10 Control
The floodlight shall include an LED driver capable of controlling the luminaire via either an industry standard
DALI (Digital Addressable Lighting Interface) or a 1-10V control interface. Control systems (control panels)
are provided by other.
1.11 Surge Protection
The floodlight shall include an integrated two (2) stage surge protection system to protect the electronic driver
(1st stage) with a minimum surge protection rating of 10KV and the LED lighting units (2nd stage) with a test
class II surge protection.
1.12 Colour Rendering Index
The floodlight shall have a minimum colour rendering index (Ra) of 70 and a colour temperature minimum of
4,000 K for maximum efficiency.
1.13 Operational Life Expectancy
The floodlight shall have a lifetime (MTBF - Mean Time Between Failures) of 50,000 hours (L70). The lumen
output shall not drop below 70% of the initial output during this period.
