A fishing lamp system includes a LED fishing lamp and a power supply device that can convert alternating current into supply power having voltage peak and voltage valley value, since the power supply device needn’t to convert the alternating current into DC power without voltage change, the size and cost of the power supply device will be reduced without providing a coil type transformer, so as to improve the convenience and applicability of the system.本發明提供一種集魚燈系統,其主要是將LED集魚燈配合能轉換交流電成為具有電壓峰值及電壓谷值的供給電之電源供應裝置運作,由於電源供應裝置不需將交流電轉換為不具電壓變化的直流電,因此電源供應裝置不需配置線圈式的變壓器,而能降低電源供應裝置的體積、重量及成本,當然也能降低本發明整體集魚燈系統的體積、重量及成本,提高使用的便利性及適用性。
