LED Elevated Medium Intensity Runway Light (LEMIRL)
Compliance
• FAA (AC150/5345-46, EB67)
• AP-170 (Chapter 3.1)
• CASA (Manual of Standards Part 139)
• TP-312 (Aerodrome Standards and Recommended Practices)
Applications
Elevated LED fixture, medium intensity type, omnidirectional, bidirectional or unidirectional, with adjustable height and with non-flashing light for runway edge, runway end and IFR non-precision instrument runways.
• Runway edge: FAA AC150/5345-46 L861, AP-170 Vol II §6.1, CASA MOS 139 §9.10 , TP-312 §5B-1 (medium/low intensity)
• Runway threshold: FAA AC150/5345-46 L861E, AP-170 Vol II §6.1, CASA MOS 139 §9.10 (medium/low intensity)
• Runway end: FAA AC150/5345-46 L861E, AP-170 Vol II §6.1, CASA MOS 139 §9.10 (medium/low intensity)
• Wing bars: AP-170 Vol II §6.1
• Displaced threshold: FAA AC150/5345-46 L861, L861E, L861SE, CASA MOS 139 §9.10 (medium/low intensity)
• IFR non-precision instrument runways: FAA AC150/5345-46 L861, L861E, L861SE
• Approach area: AP-170 Vol II §6.1
• Landing zone: AP-170 Vol II §6.1
• Fillets light (rapid exit): AP-170 Vol II §6.1
Features
• Degree of mechanical protection IP68.
• Operational temperature range admitted: between -55°C (-67°F) to +55°C (131°F).
• Average life of LED: 60,000 hours at maximum intensity; 100,000 hours under normal operating conditions.
• Lower consumption compared with the traditional fixtures: lower loads, CCRs and lower-powered transformers.
• Variable light emission: in accordance with the standard FAA EB67.
• Colorimetric coordinates constant over time.
• High degree of compatibility with the existing airport installations.
• Low maintenance coefficient: fixtures designed with high modularity and minimal maintenance required over time and common spare parts for all the configurations.
• Degree of mechanical protection IP68: the seal of the dome does not require sealants.
• Absence of adjustments: the light sources are preconfigured and do not require adjustments.
• Usable with any type of constant current regulator compliant with the rules FAA or IEC.
Performance
• Electronics resistant to vibrations.
• Automatic adaptation to the frequency of the supply current.
• Equipped with surge protective device (FAA EB67).
• Geometry and structure designed to minimize the action of atmospheric precipitations on the optical emission of the fixture.
