Abstract

This study analyzed characteristics of 240 W high power LED lamps by comparing with those of traditional metal halide lamps. In addition, it analyzed the propriety of LED lamps as a source of light, considering seawater transmission characteristics. When Applying white LED package with the color temperature color temperature of 6500K, a 240W-LED fishing lamp has a characteristics of the luminous angle to be expanded to ${\pm}45^{\circ}$, the illumination change was improved to 0.8, as well as the luminance efficiency was improved to 98.8lm/W. As results of comparison between one 1,500W-metal halide lamp and four 240W-LED lamp with considering a seawater transmission and a luminous efficiency of scotopic vision, the radiant flux of two lamps were almost equal level at 50m depth and the luminous flux was 5% higher LED lamp than metal-halide lamp even if only applying the luminous efficiency of scotopic vision. As the luminous flux of LED lmap was 14% higher than that of metal-halide lamp with applying the luminous efficiency of scotopic vision to radiant flux at 50m depth, so LED fishing lamp was verified to alternative possibility of metal-halide lamp.

본 연구에서는 240 W급 고출력 LED 집어등의 특성을 기존 메탈 집어등과 비교하여 배광 패턴의 특성 및 광효율을 분석하고, 파장 대역의 특성을 해양 투과 특성 및 시감도를 고려하여 집어등 광원으로써 적정성을 분석하였다. 색온도 6500 K, white LED 패키지를 적용한 240 W LED 집어등의 특성을 보면 배광각은 ${\pm}45^{\circ}$, 조도 변화률이 0.8로 개선되었으며, 광효율은 98.8 lm/W로 향상되었다. LED 집어등의 해수의 투과율과 인간의 암순응시 시감도를 1,500 W 메탈등 1개와 4개의 240 W LED 집어등에 적용하여 비교한 결과, 방사출력이 수심 50 m에 이르면 거의 동등하였으며, 암순응시 시감도만을 적용한 경우에도 LED 집어등이 약 5 % 정도 높은 광속을 나타내었으며, 수심 50 m의 방사출력에 암순응시 시감도를 적용한 경우 LED 집어등의 광속이 14 % 높게 나타나 메탈등의 대체 가능성을 확인할 수 있었다.
