This lantern is composed of solar battery, maintenance-free storage battery, Fresnel lens, base, microcomputer integrated flasher, and LED light source daylight sensitivity.It has seven solar panels, six of which are embedded into the base to form a hexagon, and the last circular one is installed on the top of the lens. The Fresnel lens and the cover are jointed by stainless steel screw and the same as the cover and the base. The maintenance-free battery is put inside the base. The inner core is composed of microcomputer integrated flasher and daylight switch with LED light source in it. Through coding, it can produce256 light characters (up to IALA or national GB4696-84 standard) and through RS232 or 485 interface, it can realize remote control. This lantern is widely used as buoy light, bank light in coastal waters, inland rivers and obstruction light of high constructions.
