This creation is a kind of buoy structure improvement,Specifically include that subscript ontology,Luminous sensing element,Buoy ontology and power supply supply element,An at least transmittance section is arranged in the mark tail of subscript ontology one end,The sensing element that shines is arranged what installation space and has electrically conducting contact,The movable setting power supply of the accommodating space of buoy body defining supplies element,Power output part and electrically conducting contact on power supply supply element is in electrical contact,Thereby,Buoy ontology in the what water of position is made power supply supply element by influence of hydraulic pressure makes power output part excite the sensing element that shines to generate light simultaneously with electrically conducting contact electric connection and be distributed by transmittance section in turn towards luminous sensing element is mobile,Buoy is allowed to can pass through light to promote fish news accuracy.本創作是一種浮標結構改良，主要包括:上標本體、發光感應元件、浮標本體及電源供應元件，上標本體一端的標尾設置至少一透光部，發光感應元件設置於安裝空間且有導電接觸部，浮標本體界定的容置空間可活動設置電源供應元件，電源供應元件上的電源輸出部與導電接觸部電性接觸，藉此，位於水中的浮標本體受水壓影響使電源供應元件朝發光感應元件移動進而使電源輸出部與導電接觸部電性連接同時激發發光感應元件產生光線並由透光部散發，讓浮標可透過光線來提升魚訊準確性。
