The present invention relates to an underwater fishing lamp system with a repeatedly flashing full-color LED, which comprises a plurality of full-color LED (RGB LED) light sets, a signal distributor and a main controller. The light sets are fixed in a set net, and the signal distributor connected to each of light sets includes a LED driving circuit. The main controller is used to receive computer signals and transmit modulated signals to the signal distributor. As a result, using the light sets can be chosen and modulated into lamplight with various colors to achieve the main purpose of attracting aquatic creatures in various seasons. Still, the light sets can be set with a specific continuous time of period or time intervals for repeatedly flashing to guide aquatic creatures to swim into a second box net of the set net, and to avoid aquatic creatures swim far from the light source due to their adaption or tiredness to lamplight or changes of environment, after their photokinesis in nature for a time span.本發明係關於一種全彩發光二極體循序閃爍水下集漁燈具系統,包括複數個全彩發光二極體〈RGB LED〉燈組、訊號分配器以及主控制器。全彩發光二極體燈組固定於定置漁網〈set net〉中,訊號分配器連接各個全彩發光二極體燈組,訊號分配器包含LED驅動電路;主控制器可接收電腦訊號,並將調變之訊號傳送至訊號分配器。據此,運用發光二極體燈組能選擇與調變成不同色彩之燈光,以滿足吸引不同時節魚群之目的。並設定循序閃爍所需時間與間距以導引魚群往定置漁網的第二箱網中,且能避免魚群趨光一段時間後,會因對光的適應、疲勞以及環境的變化等而離開光源。
