Abstract
This product is a lighting device that is required to be installed on roll-on / roll-off passenger ships under the SOLAS Convention (International Convention for the Safety of Life at Sea) established by the International Maritime Organization (IMO). It also incorporates a nickel-metal hydride battery that automatically supplies power when the ship's power supply fails, and a control board that controls charging and lighting, as well as detecting the power supply of the emergency power supply. It keeps the necessary power constantly charged, and when the main power supply, emergency power supply, and temporary emergency power supply all cease to function, it automatically supplies power from the built-in battery, maintaining illumination performance of above the specified illuminance for more than 3 hours, regardless of the tilting condition, and in the event of a power outage caused by a disaster on board the ship, it suppresses panic and clarifies evacuation routes, thereby enabling safe and smooth evacuation.
