集鱼灯海面照度计算方法的比较研究

Comparative Study on the Calculated Methods of Illuminate of Sea Surface about Aggregating Fish Lamps

介绍了集鱼灯海面照度计算的3种常用方法,并建立一种新的照度计算方法。根据鱿钓渔船集鱼灯布置的尺度数据,参照DC-2000W型集鱼灯的配光特性,对船舷一侧的海面照度分别用4种照度计算方法进行了计算。通过对各方法的计算结果比较和各方法建立的前提探讨,指出新照度计算方法的合理性和相对精确性。

The paper introduced three calculated methods of illuminate of sea surface about aggregating fish lamps,then took out a new method to the calculation. Based on the dimension of one squid jigging ship,using luminous intensity of DC-2000W metal halide lamp, the sea surface illuminate of one side of the ship was calculated by the four methods respectively.And by the comparison of the four different calculated results,it shows that the new calculated method is more suitable and more accurate.
