I. Intelligent Aviation Obstruction Light - Model HD-155 (Medium & High Intensity)
1. General Overview
The main control unit of the Model HD-155 intelligent aviation obstruction light utilizes a CPU microcontroller chip manufactured by ATMEL (USA). It automatically controls an internal, laser-specific energy storage component to provide high-voltage DC and ignition voltages exceeding 10,000 volts. This powers 2 to 4 pulse-strobe xenon cold-light source tubes, generating powerful instantaneous flashes in cycles every few seconds.
2. Advantages of the Aviation Obstruction Light
① It is equipped with 2 to 4 pulse-strobe xenon cold-light source tubes at once, achieving a lifespan of approximately 20 years;
② Its greatest advantage lies in the light source: it utilizes high-power, low-energy-consumption pulse-strobe xenon cold-light tubes manufactured by PerkinElmer (USA).
③ The internal system features a thermal protection circuit with constant temperature control as well as lightning protection devices.
II. Intelligent Aviation Obstruction Light - Model HD-155LED (Long Lifespan)
1. General Overview
The lens cover of the Model HD-155LED intelligent aviation obstruction light is made of imported sunlight-resistant polymethyl methacrylate (PMMA), molded into a 155mm Fresnel lens. The base of the fixture is die-cast from aluminum alloy and treated with a classic powder-coating process. For illumination, it uses an imported LED light array featuring an ultra-long lifespan, high luminous efficacy, and extremely low power consumption. The LED light array can last up to 20 years.
2. Advantages of the Aviation Obstruction Light
Compact size, lightweight, anti-aging, corrosion-resistant, and highly durable.
3. Selection of Synchronized Flashing Control Methods for Aviation Obstruction Lights
① Standard Type: Uses a centralized control box for aviation obstruction lights to achieve synchronized flashing;
② Smart Type: Connects via synchronization signal cables in a daisy-chain configuration to achieve synchronized flashing;
③ Digital Type: Utilizes power line carrier (PLC) wireless remote control technology to achieve synchronized flashing;
④ GPS Type: Equipped with a GPS global satellite time synchronization module. Unrestricted by spatial distance, it achieves synchronized flashing at any location worldwide.
III. Main Technical Parameters of the Intelligent Aviation Obstruction Light: (as shown in the figure below)
Note: The luminous intensity of 200,000 cd is achieved by the alternating flash of two groups consisting of four pulse-strobe xenon tubes.
IV. Installation Positions for Intelligent Aviation Obstruction Lights
① For tall objects higher than 90m but less than 150m, medium-intensity obstruction lights should be installed at the top. Additional obstruction lights should also be added at intermediate levels, spaced as equally as possible.
② Ultra-high voltage transmission line towers should be equipped with high-intensity obstruction lights in a three-level sequential flashing configuration. The positions should be at the top of the tower, the lowest sag point of the cables, and the midpoint between the two.
③ Obstruction lights installed on buildings with large footprints should allow the outline of the object to be visible from all directions. Horizontally, a spacing of approximately 45m can be used as a reference.
V. Installation Precautions for Intelligent Aviation Obstruction Lights
① When intermediate-level obstruction lights need to be installed on buildings located near residential areas, care should be taken to avoid causing annoyance to residents. The general requirement is that only scattered/spill light should be visible from the ground.
② Obstruction lights on tall buildings and structures should be installed within the 45-degree protection zone of a lightning rod.
③ If there are significant voltage fluctuations in the power grid, a voltage stabilizer (regulator) should be connected in series.
