Case Study: AH-MI-B2(L) Aviation Obstruction Light Safeguards Urban High-Rise Building Airspace

Reliable Obstruction Lighting Keeps Urban Airspace Safe Around the Clock

A newly constructed high-rise building in a busy urban district required ICAO-compliant obstruction lighting to alert low-flying aircraft and helicopters operating near the city skyline. The property developer selected the AH-MI-B2(L) Aviation Obstruction Light from SHENZHEN ANHANG TECHNOLOGY. This case study explains the decision — in a Q&A format.

Q: Why was an aviation obstruction light required for this building?

The high-rise building stands over 45 meters tall, located within a densely built urban corridor frequently traversed by medical helicopters, police aviation, and general aviation traffic. Under ICAO and CAAC regulations, structures exceeding 45 meters must be marked with obstruction lighting to ensure they are clearly visible to pilots, especially during nighttime and low-visibility conditions. The developer needed a reliable, low-maintenance solution that could operate continuously without interruption.

Q: What is the AH-MI-B2(L) Aviation Obstruction Light?

The AH-MI-B2(L) is a medium-intensity red beacon designed for obstacle marking on high-rise buildings, telecommunication towers, chimneys, and other tall structures. It utilizes high-efficiency LED technology to produce a steady or flashing red signal visible from several kilometers away. Built with a rugged, UV-protected housing and an IP66 waterproof rating, the AH-MI-B2(L) is engineered for continuous outdoor operation in all weather conditions.

Q: What are the key technical advantages of the AH-MI-B2(L)?

• High-Intensity LED Array: Delivers powerful red illumination with low energy consumption, ensuring maximum visibility for pilots while minimizing operating costs.
• Compact & Lightweight Design: The streamlined housing makes installation straightforward — a single technician can mount and wire the unit on the rooftop or parapet wall with minimal equipment.
• All-Weather Durability: IP66-rated enclosure with UV-protected and anti-corrosion materials withstands rain, dust, extreme heat, and freezing temperatures year after year.
• Long Service Life: LED light source rated for over 100,000 hours, dramatically reducing the need for bulb replacements and routine maintenance visits.

Q: How did the installation go?

The AH-MI-B2(L) unit was installed on the building's rooftop by a two-person crew in a single afternoon. Its compact form factor and standard mounting bracket meant no custom fabrication was needed. Once powered, the light began operating immediately — flashing at the specified ICAO rhythm of 20–60 flashes per minute. The building passed its aviation safety inspection on the first attempt.
