High-Rise Buildings Aviation Obstruction Lighting in China

Applications: High Building

End Users: Poly Development Holding Group Co., Ltd, Heguang Chenyue Project

● CK-15-T Medium Intensity Type B Solar Obstruction Light


Poly Heguangchenyue is the first time that the central enterprise Poly has introduced high-end products of the "Heguang series" to create a million-square-meter low-density large-scale project that is scarce in the city. The project is located in the head area of Longcheng Street, and covers 85-160 square meters of small high-rises, bungalows, and villas Can meet different housing needs.

According to the International Civil Aviation Organization (ICAO), high-rise buildings and other structures that are hazardous to aircraft need to have aviation obstruction lighting. Different building heights require a different intensity of obstacle lights or a specific combination.

Basic Rules

Aviation obstruction lights set in high-rise buildings and buildings should be able to show the outline of the object from all directions. The horizontal direction can also be referenced to set obstruction lights at a distance of about 45 meters. Generally, the obstruction lights should be installed at the top of the building, and the installation height H should be from the horizontal ground.

● Standard: CAAC、ICAO、FAA 《MH/T6012-2015》《MH5001-2013》

● The number of light levels recommended depends on the height of the structure;

● The number and arrangement of light units at each level should be placed so the lighting is visible from every angle in azimuth;

● Lights are applied to display the general definition of an object or a group of buildings;

● Width and length of buildings determine the number of aircraft warning lights installed at the top and at each light level.

Lights Specifications

● Low intensity aircraft warning lights should be used for structure with H ≤ 45 m during night time, if those are considered inadequate, than medium – high intensity lights should be used.

● Medium intensity aircraft warning lights type A,B or C should be used to lit extensive object (group of buildings or tree) or structure with 45 m < H ≤ 150 m.

Note: Medium intensity aircraft warning lights, type A and C should be used alone, whereas medium intensity lights, Type B should be used either alone or in combination with LIOL-B.

● High intensity aircraft warning type A, should be used to indicate the presence of an object if its H > 150 m and an aeronautical study indicates such lights to be essential for the recognition of the object by day.


The customer required a CAAC-compliant nighttime warning light system for the high building. The system needed to be low-cost, quick and easy to install and completely self-contained with an integrated power supply and fully automated to enable the lights to activate at dusk and deactivate at dawn.

A low-maintenance lighting system was also needed that wouldn’t require constant repairs or component replacement and that would run reliably for many years with minimal operator intervention. If maintenance was required, however, the light fixtures or their components needed to be easily replaced without interrupting or affecting the building’s operation or the performance of the lights on other buildings close by.

Medium Intensity Solar Obstruction Light (MIOL), multi-LED type, compliant to ICAO Annex 14 Type B, FAA L-864 and Intertek & CAAC(Civil Aviation Administration of China) certified.

This product is the ideal solution when looking for a reliable and high-quality solar system, to be installed in areas without power supply or when a temporary obstacle light system is required.

CK-15-T Medium Intensity Obstruction Light with Solar Panel has been designed to be an assembly as compact as possible and easy to install.
