An LED light source module, its secondary optical lens, and a fish collecting lamp； the light source module includes: a module seat, a plurality of LEDs (light emitting diodes) built on the module seat, and a building An electric control unit on the module base and electrically coupled with the LED； the electric control unit is arranged in the center of the module base, and a plurality of LEDs are arranged in several concentric circles with the electric control unit as the center； the A secondary optical lens is combined with the LED on the module seat； the secondary optical lens forms an optical ring corresponding to each annularly arranged LED. The optical ring can be either a convex lens ring or a concave lens ring. If the convex lens ring is used, it is a secondary optical lens that can enhance the light-gathering effect, which can be applied to the field where light-gathering is required, especially for fishing boats as water-collecting fish lights. If a concave lens ring is used, it is a secondary optical lens with a wide-angle light output effect, which can be applied to fields that require a wide range of light distribution, such as stadiums and factories.一種LED光源模組及其二次光學透鏡、以及集魚燈；所述光源模組包括：一模組座、建置於該模組座上的多數個LED(發光二極體)、以及建置於該模組座上且與該LED電性耦合的電控單元；該模組座的中心設置該電控單元，多數個LED以該電控單元為圓心呈數個同心圓環狀排列；該模組座上相對該LED組合一二次光學透鏡；該二次光學透鏡對應每一環狀排列的LED成型一光學環。該光學環可為凸透鏡環或凹透鏡環之擇一。若採用凸透鏡環則為一種可增強聚光效果的二次光學透鏡，可應用於需要聚光的場域，特別是應用於漁船做為水上集魚燈。若採用凹透鏡環則為一種廣角出光效果的二次光學透鏡，可應用於需要大範圍配光的場域，例如球場、廠房。
