Navigation lights solar marine boat lights is necessary for ship navigation, operation, and the life of ship management staff.
Usually includes ensuring navigation safety and personnel safety lighting (such as navigation lights, signal lights, and lifeboat area lighting), ship workplace lighting (such as bridge, engine room, and deck loading and unloading lighting), and living area lighting.
Different from land lighting systems, ship lighting systems can be divided into main lighting, emergency lighting, temporary, navigation, and signal lights according to different power supply methods.
Today RM Security mainly takes you to understand the details of navigation lights.
Navigation Lights & Signal Light System
Navigation Lights
It is an independent part of the ship’s lighting system and an important light signal to ensure the safe navigation of the ship at night. In any case, it must be bright to indicate the ship’s position, status, type, whether there is a tugboat, etc., so as to prevent misunderstandings by surrounding or passing ships and cause marine accidents.
The navigation lights are composed of front mast lights, main mast lights, tail lights, left and right side lights and front and rear anchor lights.
They are used for the night navigation of ships and indicate the status and corresponding position of ships.
The bridge is equipped with a dedicated navigation light control box or control panel, which is powered by two circuits of the main switchboard and the emergency switchboard.
Navigation light bulbs are generally 60W twin-filament incandescent lamps. Each lamp is a double set, one of which is used as a spare, which can be switched on the control box.
Signal Light
It is the light sign of the ship in various special situations, especially when sailing at night, and it is one of the indispensable communication tools. The control of signal lights is generally concentrated on the bridge, requiring two-way power supply.
There are many types of signal lights. In order to meet the special requirements of ports and narrow water channels in some countries, the signal light settings of ocean-going ships are more complicated.
These signal lights are usually installed on the special signal mast or radar mast on the top of the bridge, and several (8-12) red, green, white and other all-round lights are installed in two or three rows according to regulations.
Common Navigation Lights:
(1) Mast Light
It’s a white signal light installed on the front and rear masts according to international navigation rules.
It is used to indicate the direction of the ship at night. It’s placed above the center line of the bow and stern of the ship, higher than other lights, and within 22.5° from the front of the ship to the rear of the beam on each side, and displays uninterrupted lights in a horizontal arc of 225° white lights.
It is mainly used to display the dynamics and scale of the own ship and distinguish the scale and dynamics of other ships, and it is also a visual device for judging the situation of ships encountering and approaching encounters.
(2) Sidelight
Refers to the red light installed on the port side that emits uninterrupted red light in a horizontal arc of 112.5° from the bow to the left when the ship is sailing, and the red light that is installed on the starboard side from the bow to the right when the ship is sailing.
A general term for green lights that emit uninterrupted green light in a horizontal arc of 112.5°. The device is to enable the lights to be displayed within 22.5 degrees from the front of the ship to the rear of the beam on each side.
(3) Tail Lights
White lights were placed as close to the stern as possible to show uninterrupted light. A horizontal arc of 135° is displayed within 67.5° from directly behind the ship to each side. Its visibility distance is required to be 3 and 2nmile respectively according to the length of the ship.
It is used to display the dynamics of own ship and distinguish the dynamics of other ships, and to judge the situation of ships crossing or overtaking.
(4) Towing Lights
Placed above the taillights, with the same 135° horizontal light arc as the taillights. According to the “International Regulations for Avoiding Collisions”, the towing lights of ships with a length of 50 meters or more require a minimum visibility of 3 nautical miles, and those with a length of less than 50 meters require visibility of 2 nautical miles.
(5) All-round Light
Refers to a light that displays uninterrupted light within a 360-degree horizontal arc.
For example, a white all-round light at the front of the ship is an anchor light. The front anchor light should be higher than the rear anchor light by more than 4.5m , when the length of the ship is greater than 50m, the height of the front anchor light should be greater than 6m above the hull.
(6) Instrument Indicator Lights
Lights that reflect the working conditions of the indicated equipment can be seen in many places on board.
(7) Lighthouse
It is a large-scale fixed navigation aid. The main structure is generally tower-shaped, and high-intensity light-emitting devices are installed on the top. The light range is generally 15-25 nautical miles.
Lighthouses are used for ships to determine the position of the ship, determine the direction of navigation, guide the ship to navigate or indicate dangerous areas (dangerous sandbars or reefs and channels leading to the mouth of the port).
It is often installed near important waterways, coasts, ports, rivers, or dangerous obstacles with a wide view. However, with the rapid development of navigation technology and the establishment of the integrated navigation systems of radar transponder.
DGPS system and AIS ship automatic identification system, the navigation function of lighthouse is weakened more and more, and the value of navigation is decreasing day by day, but it has a potential history.
Cultural value has become the human geographic coordinates sought after by all countries.
(8) Buoys & Light Buoys
Refers to a kind of navigation mark floating on the water surface, which is anchored at a designated position to mark the range of the channel, indicate shoals, obstructions, or indicate special-purpose surface navigation aids.
The number of buoys is the largest among the buoys, and they are widely used. They are installed in places where it is difficult or unsuitable to set up fixed buoys.
Buoys equipped with lights are called light buoys, which are used to aid navigation in day and night navigable waters.
To sum up, light language is a communication tool. Ships sailing at sea at night rely on the changes of various lights to communicate and communicate.
The solar marine navigation lights produced and exported by Rongman Security are based on IALA standards to ensure the normal safety of ships. orderly traffic.
When we choose solar navigation lights, we must choose the right one according to the specific criteria, requirements, and quality.
