Star Standard was founded in 2012, since the foundation Star Standard is focusing on aviation obstruction lights(AC&DC type available).Star standard offers a complete range of standard and custom aviation obstruction lighting system for high structures inclusive of RF towers, wireless communication towers, etc. All series of aviation obstruction lights are designed and manufactured in compliance with ICAO standard, we have a strong R&D team, can customize all kinds of aviation obstruction lighting system or solution for clients across the globe, we also can provide critical lighting and hazard marking lights in the toughest conditions around the world, our clients are mainly from Asia, Russia, South America, Africa.

All aviation obstruction lights are manufactured in ISO9001:2015 certified factory in China’s “Silicon Valley”—Shenzhen City,China.

Our aviation obstruction lights are ICAO certified.

Application

Aviation obstruction lights are widely used in places such as broadcasts,cranes and infrastructures,marines,mining,railyards,telecommunications,high buildings,etc.

Classification and naming of aviation obstruction lights

According to ICAO standard, the classification of aviation obstruction lights are as follows:
a) L-810, low-intensity red steady burning obstruction light
b) L-856, high-intensity white flashing obstacle light, 40 flashes/min
c) L-857, high-intensity white flashing obstacle light, 60 flashes/min
d) L-864, medium intensity red flashing obstruction light, 20 flashes/min-40 flashes/min
e) L-865, medium intensity white flashing obstacle light, 40 flashes/min
f) L-866, medium intensity white flashing obstruction light, 60 flashes/min
g) L-885, medium intensity red flashing obstruction light, 60 flashes/min

Aviation obstruction lights are generally divided into low intensity, medium intensity and high intensity. The vertical and horizontal distances of aviation obstruction lights are greater than 45m for buildings and their facilities, and the 3 types of obstruction marker lights can be used in conjunction with each other. Aviation obstacle indicator classification
Below 45m above the ground, low-intensity aviation obstruction lights should be set up in relatively open surroundings, which are always bright red(steady burning type)

45-105m buildings, use medium-intensity B-type aviation obstruction lights as red flashing lights, the flash frequency should be between 20-60 times per minute, and the effective light intensity is 2000cd±25%.

105-150m buildings,use medium-intensity type A aviation obstruction light; white flashing, effective light intensity (2000-20000cd) ± 25%.

Above 150m, use high-intensity obstacle signs and must be white flashing lights. The flash frequency should be between 40-60 times per minute. The effective light intensity depends on the brightness of the background. It works 24 hours a day.

Obstacles should mark the highest point and the extreme edge (ie, apparent height and width) of the obstacle. The distance between the middle layer must be no more than 45m, and the height of the city should be more than 100m. Special consideration should be given to adding aviation obstruction lights to the middle floors of buildings.

The vertical and horizontal distances of aviation obstruction lights should not be greater than 45m (that is, if the top of the object is more than 45m above the ground, the beacon must be obstructed in the middle)
For chimneys or other buildings of similar nature, the top obstacle marker light should be located between 1.5-3m from the top, taking into account the pollution of the chimney to the lamps.


The aviation obstruction light can be located 4-6m below the chimney mouth.Ultra-high objects higher than 150m should be used in conjunction with medium and high-intensity aviation obstruction lights.
For high-voltage power transmission cables and towers less than 150m high, a white light-emitting medium-intensity aviation obstruction light can be installed on the top.

Regardless of the aviation obstruction lights, the number and arrangement of the aviation obstruction lights at different heights should be able to see the object or the “group outline” of the object from all aspects, and consider the simultaneous and sequential flashing of the obstruction lights to achieve Obvious warning effect.

  1. The low-intensity obstruction light is constant light, red, and the peak light is stronger than 32.5cd. Generally, it is not used alone, but must be used in conjunction with medium-intensity and high-intensity obstruction lights. For example, the buildings and facilities above 45m are equipped with multi-layer medium-intensity or high-intensity obstruction lights, and low-intensity obstruction lights can be set between medium-intensity or high-intensity obstruction lights. (The low-intensity obstruction light is red, the effective light intensity is 32.5Cd)
  2. Medium intensity obstruction lights are divided into 3 types according to luminous requirements:
    a. The medium-intensity A-type obstruction light is a white flash with an effective light intensity of 20000cd-2000cd. It is used for buildings and facilities above 105 meters and obstacles with strong background light or used with high-intensity B-type light dimming.
    b. The medium intensity B-type obstruction light is a red flash, and the effective light intensity is 2000cd±25%.
    C. Medium intensity C-type aviation obstruction light is red constant light, effective light intensity is 2000cd±25%.
  3. The high-intensity obstacle lights are divided into two types according to the luminous requirements:
    a. The high-intensity type A obstruction light is a white flash, and it flashes with variable intensity at day, dusk or dawn and night. The effective light intensity is 200000cd±25% in daytime; 20000cd±25% at dusk or dawn; 2000cd±25% at night ; Mainly used for buildings and their facilities over 150 meters, or used in conjunction with medium intensity obstruction lights.
    b. The high-intensity B-type obstruction light is a white flash, and it flashes simultaneously at three levels of variable light intensity at day, dusk or dawn and night. The effective light intensity is 100000 cd±25% in daytime; 20000 cd±25% at dusk or dawn; 2000cd±25%, mainly used for marking wires, cable towers and high-voltage transmission line towers.

According to regulations from the Federal Aviation Administration (FAA) and the International Civil Aviation Organization (ICAO), any structure that exceeds 45m above ground level is required to be properly marked with aviation obstruction lights. Tall structures like towers, industrial chimneys & smokestacks, and even wind turbines will need to adhere to minimum requirements in order to meet safety regulations.

The height of the structure is only one factor that must be considered when choosing how to place aviation warning lights. Structure diameter, weather, terrain, proximity to airports, and other considerations will ultimately determine the required obstruction lighting setup.

Industrial Access can help establish the proper aviation obstruction light configuration to keep you up to code and within regulations. These warning systems require special attention as regulations continue to evolve. Since requirements may vary depending on your location, the type of structure, and environmental concerns, it’s best to consult with a professional that has specific knowledge of regulation & installation requirements.

Star Standard’s R&D team of highly trained rope access technicians can quickly & efficiently install, maintain, and repair aviation obstruction lights on your tall structures or industrial chimneys. Contact us today so we can assess your high angle needs.
