Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a ship lighting device. Background Art

[0002] There are many types of ship lighting devices, including ship working lights, navigation searchlights, ship signal lights and ship emergency lights. Since ships work at night, they all use ship lighting devices.

[0003] At present, ships can provide lighting effects for ships sailing at night through searchlights. However, in actual use, people often need to adjust the irradiation distance of the searchlight, so as to switch the searchlight from long-distance concentrated irradiation to short-distance scattered light irradiation, so as to provide better lighting needs for people working near the ship. However, the existing ship searchlights generally cannot adjust the irradiation distance, so they need to be improved. At the same time, ships often go out to sea for a long time. When working at night or on rainy days, the crew needs to use lighting equipment for lighting. When the lighting equipment is used outside the cabin, the seawater will wet the lighting equipment. Since the temperature of the lighting equipment is high, the seawater will evaporate at high temperature and leave salt crystals on the transparent lampshade. Therefore, after long-term use, the salt crystals will cause the light intensity of the lighting equipment to weaken, so the lighting equipment needs to be cleaned and maintained frequently.
