A cooling system for an LED fishing lamp, comprising a fishing lamp support structure (6), a fresh water circulating system (2) and a seawater cooling system (5) the fresh water circulating system (2) comprises one or more LED lamps (1), a water pump (3), a water pipe (15) and a heat exchanger (4) the LED lamps (1) are connected via the water pipe (15) fresh water flows through a radiator (21) and a cooling chamber (13) and takes away the heat generated by the light source, and flows back to the cooling chamber (13) after being cooled at the heat exchanger (4) the seawater cooling system (5) comprises a water pump (22), a water pipe (15) and a heat exchanger (4) the heat exchanger (4) is provided with a seawater inlet (18) and a seawater outlet (16) thereon and the water pump (22) supplies seawater to the heat exchanger (4) via the seawater inlet (18), cooling the fresh water, and allows the cooled fresh water to flow out through the seawater outlet (16) and back to the ocean. The cooling system of an LED fishing lamp combines a fresh water circulating system (2) with a seawater cooling system (5) to cool a high-power LED fishing lamp, improving heat dissipation efficiency, maintaining the temperature of the LED fishing lamp in a normal use temperature range, while avoiding the problems of lamp salt accumulation and corrosion, extending the service life of the lamp.本創作係一種LED集魚燈冷卻系統,淡水循環系統包括一個或一個以上LED集魚燈、水泵、水管和換熱器,LED集魚燈之間用水管連接,淡水流經散熱器冷卻室帶走光源產生的熱量,流到換熱器處被冷卻後回流到冷卻室;海水冷卻系統包括水泵、水管和換熱器,換熱器上有進水口和出水口,水泵透過進水口向換熱器供海水,將淡水冷卻後,從出水口流出,流回大海。本創作利用淡水循環系統和海水冷卻系統相結合方式對大功率LED集魚燈進行冷卻,提高了散熱效率,使LED集魚燈的溫度始終維持在正常使用溫度範圍內,同時避免了燈具結鹽和腐蝕問題,延長了燈具的使用壽命。1‧‧‧LED燈具2‧‧‧淡水循環系統3‧‧‧水泵4‧‧‧換熱器5‧‧‧海水冷卻系統6‧‧‧集魚燈固定架15‧‧‧水管16‧‧‧海水出水口17‧‧‧淡水出水口18‧‧‧海水進水口19‧‧‧淡水進水口22‧‧‧水泵
