Why are the lights in the lighthouse intermittent?

The lighthouse is a tower-shaped luminous lighthouse built near the key part of the waterway? A lighthouse is a fixed navigation mark used to guide ships or indicate dangerous areas?

Does the modern large lighthouse structure have a good life? Communication facilities where managers live? According to different needs, different colors of lights and different types of fixed lights or flashlights are set, and the range of lights is generally 27 km to 46 km?

Lighthouses are necessary equipment to guide the course of ships? Lighthouses are usually built high by the sea, or stand on rocks that rise in waves. Their lights can guide ships to avoid dangerous rocks and follow the right route?

Have you observed it? The lights in the lighthouse are not always on, but are turned on and off regularly? Why is this? Wouldn't it be better to wear it?

In fact, from the perspective of human vision, the flashing lights are more likely to attract the attention of ships, which is the root cause of the intermittent lights in the lighthouse?

Besides, the ship can also determine its position according to the frequency of the flashing lights of the lighthouse? Because the flashing frequency of each important lighthouse is different, such as the Walf lighthouse in Xili Islands, which flashes twice every 15 second?

According to the characteristics of the flash gap, the navigator can find out what lighthouse it is, the latitude and longitude of its position, and the reefs in the sea near the lighthouse, so that the ship can take timely measures to find a safe channel.
