The features of marine led light for boat
1. Marine lighting system (main lighting system) The ship normal lighting system, also called the main lighting system, is distributed in various living and working places inside and outside the ship, providing sufficient illumination for each cabin and workplace. The characteristics of the system are: the lighting busbars on the main switchboard supply power directly to each lighting distribution box, and then the lighting distribution box supplies power to the lighting fixtures of neighboring cabins or areas; the lighting voltage is generally AC and DC 110 V or 220 V;
Different cabins and spaces have different illumination requirements; all lighting fixtures are equipped with control switches. Normal lighting is the main lighting of the whole ship, which is powered by the main generator of the ship. All the life and work of the ship should be illuminated.
Normal lighting includes:
(1) Main cabin lighting, such as most of the ceiling light;
(2) Partial or auxiliary lighting, such as bed lights, wall lights, wash lights, etc.;
(3) Loading and unloading of strong light lighting;
(4) More than half of the indoor and outdoor walkway lighting;
(5) Sockets, etc., must be provided in each compartment. Non-essential equipment such as electric fans, refrigerators, and cabin heaters with a rating equal to or less than 0.25 kW may also be included in the normal lighting system.
2. Marine Emergency Lighting System (Large Emergency Lighting) Emergency lighting is put into use when the main power grid fails to work. Emergency lighting is supplied by the emergency switchboard via the emergency lighting distribution box. The voltage can be the same as normal lighting, and low voltage power can also be used.
The ship’s emergency lighting system is mainly distributed in important spaces in the engine room, crew members and passenger cabins, decks of boats and personnel channels. It is used for emergency lighting when the main switchboard loses power and the main lighting system fails. Its characteristics are as follows: Emergency generators are powered through emergency switchboards and dedicated lines. For passenger ships, the emergency power supply time should be greater than 36 h; for cargo ships, the emergency power supply time should generally be greater than 18 h.
