^{_{This lantern is composed of solar battery, maintenance-free storage battery, Fresnel lens,base, microcomputer integrated flasher,and daylight switch with LED light source in it.The 11 solar batteries are embedded into the base forming a cone. The Fresnel lens and the cover are welded by ultrasonic. The cover and the base are hinge jointed by stainless steel bolt. The maintenance-free battery is in the base. The inner core consists of microcomputer integrated flasher and daylight switch with LED light source in the top of it.Through coding, this lantern can produce 256 light characters (up to IALA or national GB4696-84 standard), and through RS232 or 485 interfaces,it can realize remote control.It is widely used as little buoy light ,bank light in inland rivers and obstruction light of roads.}}
