Abstract:
The present invention relates to a heat radiating structure of an LED fishing lamp having an excellent heat radiation effect by an LED installation part immerged in liquid, and an LED fishing lamp employing the same. The heat radiating structure of an LED fishing lamp of the present invention comprises: a case filled with liquid and formed of a light transmittable material; and an LED installation part including LEDs installed therein, and immerged in the liquid filled into the case. According to the heat radiating structure of an LED fishing lamp of the present invention, since the LED installation part is positioned in the case filled with the liquid such that the LED installation part is immerged in the liquid, the heat generated from the LEDs is fast transferred to the liquid and the liquid fast emits the heat to the outside, and thus the heat radiation effect of the LED fishing lamp is improved and an LED module is less damaged. Further, the LEDs are installed in the LED installation part such that the LEDs emit light in four directions including front, rear, left, and right directions (in directions of 360 degrees centering around the fishing lamp), thereby freely implementing the light emission angle.

본 발명은 빛을 발산하는 오징어 낚시용 유인구바늘조립체에 관한 것이다. 본 발명의 유인구바늘조립체는 복수 개의 바늘이 위치된 낚시바늘설치부; 형광물질을 포함하고 있어 집어등에서 발산되는 빛을 받으면 빛을 발산하도록 되어 있고, 낚시바늘설치부의 상부에 위치되어 있는 타원형의 유인구; 낚시바늘설치부와 타원형의 유인구 사이에 위치되어 간격을 유지하는 간격유지구;를 포함하여 구성된다. 본 발명의 오징어 낚시용 유인구바늘조립체는, 타원형의 유인구가 형광물질을 갖는 것이어서 집어등에서 발산되는 빛에 의해 빛을 발산하므로 오징어가 유인구바늘조립체 주변으로 더 원활하게 모여들고, 낚시줄을 당기면 더 잘 낚이므로 어획량이 증가되는 효과가 있다. 또, 유인구의 외측면과 중공의 내벽에 형광물질이 코팅되어 있고, 유인구의 중공 중 양쪽 끝부분에 위치되어 중공의 내부로 물이 유입되는 것을 방지하는 패킹이 구비된 경우 형광성이 우수하도록 형광물질을 위치시키는 것이 용이할 뿐만 아니라 오랫동안 빛을 원활하게 발산하여 그 수명이 긴 특징이 있다. 또, 타원형의 유인구가 폴리카보네이트(Polycarbonate) 재질로 구현된 경우 내구성이 우수한 특징이 있다.
