A kind of luminous buoy of multi-optical segment,It include a buoy ontology,In the one setting what buoy ontology and lamp source portion of one light of offer,And one guide the light light guide section external to the buoy sheet,Its characteristic includes the spaced luminous zone of plural number in the what light guide section,The luminous zone is axially opened up with plural number along the light guide section and spaced recess transmittance section,And enable the light maintain the reflecting part transmitted in the what light guide section between the what recess transmittance section of plural position,Wherein,Each recess transmittance section of each luminous zone is mutually staggered along vertical axial. Accordingly, the part light can pass out the recess transmittance section, and the part light can continue to be totally reflected in the what light guide section and be transferred to next luminous zone by the reflecting part, so reach the radiance of multistage and brightness uniformity.一種多光段的發光浮標，包含有一浮標本體，一設置於該浮標本體內並提供一光線的燈源部，以及一引導該光線至該浮標本體外的導光部，其特徵在於該導光部包含有複數間隔設置的發光區，該發光區具有複數沿著該導光部軸向開設且間隔設置的凹陷透光部，以及複數位於該凹陷透光部之間令該光線維持於該導光部內傳遞的反射部，其中，每一該發光區的每一該凹陷透光部沿著垂直軸向相互錯開。據此，部分該光線會傳遞出該凹陷透光部，而部分該光線會藉由該反射部繼續全反射於該導光部內並傳遞至下一個該發光區，如此即達成多段且亮度均勻的光芒。
