Marine Navigation Mark Light / Beacon Light
Navigation mark light is a kind of traffic light which is installed on some beacons to ensure the safe navigation of ships at night. It emits the specified light color and flash frequency (the frequency can be 0) at night to reach the specified illumination angle and visibility distance.
Classification and function
There are four kinds of beacon lights: fixed beacon, light buoy, lightboat and lighthouse.
Fixed beacons, light buoys and lightboats are beacons for navigation and warning.
The lighthouse sends an identifiable signal at night on the sea for the ship to determine the location and provide a hazard warning to the ship. The beacon light uses a battery as a power source. Small lighthouses have adopted solar cells, while large lighthouses use diesel generator sets as the main source of power.
