| 摘 要： | 使用高光谱剖面仪Hyperspectral profilerⅡ对国产300 W型绿光LED集鱼灯的光学特性进行了测量,并与国产1 kW型金属卤化物集鱼灯进行比较.结果表明:1kW型金属卤化物集鱼灯的光谱范围不仅包含整个可见光(波长为380～760 nm),并有部分紫外和红外光线,而绿光LED集鱼灯的光谱辐射量主要集中在绿光波段(490～560 nm),没有紫外线；绿光LED集鱼灯和1 kW型金属卤化物集鱼灯在空气中的衰减系数分别为0.2527和0.2494；当绿光LED集鱼灯总功率为9 kW(30盏×300 W)时,其0.01 lx照度分布的最深距离为85 m,而金属卤化物集鱼灯总功率为62 kW(62盏×1 kW)时,其0.01 lx照度分布的最深距离却仅为50 m.本研究表明,绿光LED集鱼灯具有良好的水中穿透性,且不会对船员的眼睛和皮肤产生负面影响,节能效果明显.

| Abstract: | Optical characteristics of domestic green light LED with power 300 W was measured by Hyperspectral profiler II,and compared to domestic metal halide lamp with power 1 kW.Spectrum of metal halide lamp was found to cover visible light band and part of ultraviolet light and infrared light.Radiant energy of LED was concentrated on green light band（490-560 nm）without ultraviolet light.The attenuation coeffcient of light was found to be 0.2494 for metal halide lamp and 0.2527 for LED.The depth at 0.01 lx was 85 m as total power of LED was 9 kW（30×300 W）,and it was 50 m by 62 kW（62×1 kW） metal halide lamp.The green light LED not only had rays being penetrated into deep water,leading to save energy efficiently,but also had less harm to the eyes and skin of the crew. |
