This is a kind of fish trap lamp that exchanges specific light wavelength.Including a heat sink,One circuit board,A plurality of first light-emitting elements,Complex second light emitting element,One driving unit,I. control unit,A transparent cover,The circuit board is fixed on the heat sink；And the complex number of first light-emitting elements,A plurality of second light-emitting elements are arranged in front of the circuit board.It can output wavelength light through different depth of water.And the driving unit is arranged on the circuit board.And with the first,2. Electrical connection of light-emitting elements,All the first light-emitting elements or all the second light-emitting elements can be driven respectively.And the control unit and the first,2. Electrical connection of light-emitting elements,And it can control all the first light-emitting elements or all the second light-emitting elements.It can attract fish in different depths.And the transparent cover is arranged at the front position of the corresponding circuit board.And can cover the circuit board；And the waterproof part is arranged between the transparent cover and the heat sink；In this way, we can induce fish at different depths by controlling the transmission depth of specific light wavelength to the sea water.本創作係一種交換特定光波長之誘魚燈具，包括一散熱座、一電路板、複數第一發光元件、複數第二發光元件、一驅動單元、一控制單元、一透明罩，其中該電路板固設於散熱座上；又該複數第一發光元件、複數第二發光元件設於電路板前方，並可分別輸出穿透水中不同深度之波長光線；又該驅動單元設於電路板上，並與第一、二發光元件電性連接，可分別驅動全部第一發光元件或全部第二發光元件發光動作；又該控制單元與第一、二發光元件電性連接，並可控制全部第一發光元件單獨發光動作或全部第二發光元件單獨發光動作，並可吸引不同水下深度之魚群；又該透明罩設於對應電路板前方位置，並可覆蓋電路板；又該防水件設於透明罩與散熱座間；藉此本創作可藉由控制交換特定光波長對於海水透射深度不同以誘引不同深度魚群功效。
