The role of lighthouse

Its main function is to provide navigation and warning for ships sailing at sea.

They are usually located along the coastline or important waterways, providing clear direction and location information for ships. In ancient times, due to the lack of accurate maritime positioning technology, ships often traveled along the coastline, so the existence of lighthouses was very important. The working principle of lighthouse is that by sending out specific light signals, such as specific color lights and specific flashing rhythm, these signals can help ships find the right course in dark or bad weather and avoid hitting rocks or other dangers. Each lighthouse will have its own unique light quality color and flashing rhythm, so as to distinguish it from the adjacent lighthouses, so that sailors can observe the light quality and rhythm at night and compare it with the lighthouses marked on the chart, and then judge whether their position is yaw and safe according to the compass bearing relative to the lighthouses.
