A kind of fish gathering lamp using what lights fishery is on settable one ship of what. Fish gathering lamp includes a lamp holder, a cage, a smooth shadowing elements and a light emitting source. Cage has a plurality of transmittance sections and an opening. The opening of cage is arranged what lamp holder, makes to form an accommodating space between cage and lamp holder. Light emitting source is electrically connected what lamp holder, and to give off light among the what accommodating space of position. Light shadowing elements link the transmittance section of what cage and covering part point, with the light source of shielding portion point. The position of light shadowing elements is suitably adjusted, the light source on direct irradiation what ship deck can be reduced, and then the ultraviolet light composition direct irradiation what ship deck in light source can be reduced.一種應用於燈火漁業的集魚燈燈具，其係可設置於一船舶上。集魚燈燈具包括一燈座、一籠架、一光遮蔽元件以及一發光源。籠架具有複數個透光部及一開口。籠架之開口套設於燈座，使籠架與燈座之間形成一容置空間。發光源電性連接於燈座，並位於容置空間之中以輻射出光線。光遮蔽元件連結於籠架並覆蓋部分之透光部，以遮蔽部分之光源。適當地調整光遮蔽元件的位置，即能夠減少直接照射於船舶甲板上的光源，進而可減少光源中的紫外線成分直接照射於船舶甲板。
