According to national standards, high-rise buildings whose tops are more than 45 meters above the ground must be equipped with navigation lights.
In order to be different from general-purpose lights, the beacon lights are not always on but flashing, and the flash frequency is not less than 20 times per minute and not more than 70 times per minute.
Buildings and their facilities above 90 meters above the ground: the use of medium-intensity obstacle signs is a red flash, the flash frequency should be between 20-60 times per minute, and the effective light intensity of the flash is not less than 1600cd, or the use of red high-intensity obstacles Marker lights make the flashing effect more obvious. For buildings and facilities above 150 meters from the ground, use high-intensity obstacle signs and must be white flashing lights. The flash frequency should be between 20-70 times per minute. The effective light intensity depends on the brightness of the background.
Aviation obstruction lights are classified into three categories from high to low:
High-intensity aviation obstruction lights, medium-intensity aviation obstruction lights, and low-intensity aviation obstruction lights.
1. High-intensity aviation obstruction lights are used for obstacles that are higher than 150 meters above the ground. And it is required that Type A and Type B high-intensity obstruction lights must be white flashing lights, and all Type A high-intensity obstruction lights installed on an object must flash at the same time, and the B-type high-intensity obstruction lights that indicate the existence of overhead wires or cables supporting the tower should be in sequence Flash: First is the middle light, then the top light, and then the bottom light.
2, medium-intensity aviation obstruction lights are obstruction lights used for obstacles whose height is between 45 meters and 105 meters above the ground. There are three types: Type A, Type B, and Type C. Type A medium intensity obstruction lights must be white flashes, type B must be red flashes, and type C must be red constant light. The A-type and B-type medium-intensity obstruction lights set on the same object must flash at the same time.
3. Low-intensity aviation obstruction lights are obstruction lights used for obstacles below 45 meters in height. There are two types: A type and B type. A-type, B-type and C-type low-intensity aviation obstruction lights must be a constant red light when on a fixed object, while the C-type low-intensity obstruction lights displayed on emergency and security vehicles must emit blue flashes, And the C-type low-intensity obstruction lights displayed on other vehicles must flash yellow.
Whether it's a conventional tower or a communication tower, a building, the top of a tall building, etc., safety warnings are a very important issue. Therefore, it's very important to choose a durable, standard, and high-quality (solar) aviation obstruction warning light.
