How To Install Aviation Obstruction Lights

LED aviation obstruction lights are a special lighting device designed for aviation safety and are an important part of the navigation lighting system.

The main function of this type of high-altitude obstruction light is to alert aircraft operators to the presence of obstacles through visual signs, thereby ensuring air transportation safety.

According to the relevant regulations of the International Civil Aviation Organization (ICAO) and the Civil Aviation Administration of China (CAAC), aviation obstruction lights can be divided into three categories according to light intensity:

• 1). Low-intensity obstruction lights: usually constant light, suitable for buildings below 45 meters in height
• 2). Medium-intensity obstruction lights: flash mode, flash frequency 2060 times/minute
• 3). High-intensity obstruction lights: strong flash mode, used for super-high buildings and special obstacles

Installation Guide for Aviation Obstruction Lights

The installation of solar lights and obstacle warning lights needs to strictly comply with industry specifications to ensure that their warning functions are fully utilized.

The following are 4 professional installation methods and their applicable scenarios:

1. Vertical installation

• Applicable scenarios: top floors of concrete or brick-concrete structures
• Installation points: Make sure that the base is completely in line with the building plane and use stainless steel expansion bolts to fix it
• Recommended products: YFFY-LS/G solar low-intensity aviation obstruction lights, whose integrated design facilitates vertical installation

2. Side installationz

• Applicable scenarios: side walls of buildings or special structural surfaces
• Technical requirements: The installation surface must be flat and the inclination angle must not exceed 15 degrees

3. Clamp installation

• Applicable scenarios: steel structure towers, communication towers, etc.
• Notes: A special installation fixture is required to ensure stability

3. Hoop installation

• Applicable scenarios: cylindrical structures (such as chimneys, wind turbine towers)
• Installation specifications: Select a hoop of appropriate size according to the diameter, which can support single or double lamp configurations

III. Installation Precautions

• 1. Vision guarantee: Ensure that the luminous surface of the obstruction light is not blocked by any object, and the luminous angle should cover all possible approach directions
• 2. Lightning protection measures: Lightning protection grounding should be done when installing high-rise buildings, and the grounding resistance should not exceed 10Ω
• 3. Maintenance channel: Reserve sufficient maintenance space for later maintenance
• 4. Synchronous control: When multiple obstruction lights are installed, a synchronous controller must be configured to ensure consistent flashing
• 5. Environmental adaptation: Corrosion-resistant materials should be selected in coastal areas, and low-temperature starting performance should be considered in high-cold areas

IV. Regulatory compliance requirements

• Whether it is a solar high-altitude obstruction light or an LED aviation light, its installation process must comply with the “Civil Airport
• Airfield Technical Standard” (MH5001) and “Aviation Obstruction Light” (MH/T6012) and other specifications. Pay special attention to:
• The correspondence between the height of the obstacle and the type of LED obstruction light
• The vertical spacing setting of the LED obstacle warning light
• Daytime/nighttime visibility requirements
• Backup power supply configuration (if applicable)

It is recommended to conduct a professional evaluation before installation, and consult the relevant civil aviation departments when necessary to ensure that the installation plan fully meets aviation safety requirements. Through scientific and standardized installation, aviation obstruction lights will effectively play their warning function and escort aviation safety.
