APPARATUS FOR COOLING FISHING LIGHT OF FISHING BOAT USING SEAWATER

摘要

The present invention relates to an apparatus for cooling a fishing light of a fishing boat using seawater, which can efficiently cool the high temperature heat caused by the high output of LEDs used as a light source for the fishing light. A pipe (10) for the installation of a fishing light (30) on a fishing boat (2) has a hollow inside, and seawater (1) is compulsorily circulated through the pipe (10) by using a pump (20). The pipe (10) has one side with an outer surface on which an aluminum PCB (32) for an LED module mounted with LEDs (33) is tightly attached, and the other side with an outer surface on which a rear bracket (31) for supporting, at the rear, the PCB (32) for an LED module. Silicon (70) is applied between the PCB (32) for an LED module and the pipe (10) and between the rear bracket (31) and the pipe (10). Double packing rubber (61, 62) is employed to seal the contact area between the PCB (32) for an LED module and the rear bracket (31). A press bolt (39) is secured into a press bolt hole (38) of the rear bracket (31) to tighten the PCB (32) for an LED module and the pipe (10). Hot water generated from the seawater which has passed through the plurality of fishing lights (30) is injected into a heating pipe (80) installed on the fishing boat (2). The PCB (32) for an LED module is formed into polygonal shape.
