Abstract	A marine signal lantern using a high power LED light source module was designed and was analyzed its light distribution characteristics. Its initial lens shape was configured according to paraxial optics and improved its collimator performance through optimization. C-8 type tungsten filament light bulbs can be replaced by marine signal lantern utilizing a high power LED light source module. Which has 775cd brightness and satisfies Ministry of Oceans and Fisheries marine lantern specification of FWHM divergence angle ± 2.3°.
