The lighthouse is a tall tower-shaped building. Lighting equipment should be installed at the top of the tower. The location should be prominent, and it should have a specific architectural shape to facilitate the identification of ships and become one of the highest points in the port.

Due to the curved surface of the earth, the tower must be high enough so that the light can be seen by ships at a distance, but the light should not be too high to avoid being blocked by clouds and fog at high places.

Use of lighthouses.

1. Escort lights.

Lighthouses are tower-shaped luminous lighthouses built near key parts of the waterway.

2. Geographical coordinates.

With the rapid development of science and technology, the establishment of integrated navigation systems such as radar transponders, DGPS systems, and AIS ship automatic identification systems, the navigation function of lighthouses is getting weaker and weaker, and the navigation value is declining every day.

3. Military defense.

The lighthouse also had military uses in the past, for coastal defense observation, etc.

4. To declare sovereignty.

In disputed waters, lighthouses, outposts, and boundary markers are often regarded as symbols of sovereignty.
