2kW直筒型集鱼灯水中照度分布及合理配置研究

摘要

根据2 kW直筒型集鱼灯的实测配光分布，以大型光诱鱿钓渔船“新世纪52号”为例，对该船的水中照度分布进行了计算。结果表明：渔船集鱼灯总功率为360 kW时，10.000 lx的等照度曲线水平方向最远约为80 m，水深方向为32 m；0.100 lx照度最深可约至50 m，最远约为260 m；当总功率减为180 kW时，等照度曲线所在水层仅减少约5 m。以0.010 lx为诱集鱿鱼的最低照度，集鱼灯功率从180 kW增加到360 kW，有效诱集距离从620 m增加到750 m，约能增加21.1％；如能将该船的灯高增大0.5 m，则可增加12.0％的有效水体体积；如能将灯距增大0.05 m，则可增加4.4％的有效水体体积。%Based on the actual measurement of 2 kW straight type fish aggregation lamps,we calculated the underwater illumination distribution of the squid jigging vessel Xinshiji No. 52. The results show that when the total power was 360 kW,the iso-illuminance curve contours of 10. 000 lx were at the depth of 32 m;in horizontal direction,it reached 80 m. The curve contours of 0. 100 lx were at 50 m vertically and 260 m horizontally. When the total power was 180 kW,the curve contours reduced about 5 m in depth. Regard-ing 0. 010 lx as the lowest limit to attract squid,if the power was increased from 180 kW to 360 kW,attracting distance could be in-creased from 620 m to 750 m,and 21. 1% of effective attracting distance increased horizontally. If the lamps'height increased for 0. 5 m,12. 0% of the effective water volume increased. If the lamps'space increased for 0. 05 m,4. 4% of the effective water volume in-creased.
