Marine luminaires comply with marine conditions, and the protective structure of the housing is also classified according to the International Protection Standard (IP). Depending on the environmental conditions, the protection levels can be roughly divided into three types.
1.Protection
The protective lamp has the function of a light-transmitting lampshade to prevent dust and direct contact with live parts.
It is mostly used in relatively dry residences, office cabins, internal walkways and other places.
2.Waterproof type
The light source is sealed by a transparent lampshade, etc., and there is a sealing gasket between the lamp body and the lampshade. The protective structure of this type of lamps is basically the same, but the protection levels are different, including drip-proof, splash-proof, water-proof vapor, waterproof spray and wave impact resistance. For use in places subject to moisture, steam and water intrusion.
Waterproof type is divided into splash-proof type and waterproof type.
- The splash-proof type is used in places where water splashes such as the bow and stern open decks, corridors outside the main deck, and walking decks.
- The waterproof type is used in places where there is not only splashing water, but also dripping water and condensation, such as engine room, furnace room, cargo hold, refrigerated cabin, kitchen, bathroom, washroom, toilet, repair room, storage room, navigation signal machine, etc. that are susceptible to Mechanically damaged waterproof lighting fixtures not only have a solid metal shell and a transparent lampshade, but also have a solid metal grille outside the lampshade.
3.Explosion-proof type
Common forms of marine explosion-proof lights: ① explosion-proof structure, ② sealed and safe type.
Explosion-proof lights are used in places where combustible dust or explosive gas may exist under normal circumstances, such as coal bunkers, oil tanks, battery compartments, oil lamp rooms, oil pump rooms of oil tankers, deck spaces, etc.
