| 摘 要： | 通过模拟灯箱光学特性实验，根据集鱼灯灯箱的平面照度分布，利用Matlab 7.0软件建立秋刀鱼集鱼灯照度分布模型，对秋刀鱼集鱼灯灯箱内不同灯位的照明效果进行了研究。结果表明：不同灯位的集鱼灯地面照度随地面距离的增加呈现出先增大后减少的趋势；而灯箱内不同灯位的集鱼灯光强值变化规律与地面照度的变化规律不同，在距离原点1 m时均出现最大值，并且上部灯位光强＞中部灯位光强＞下部灯位光强；随着集鱼灯从上端向下端移动，光强系数k(L)逐渐减小。研究发现，中部灯位光强变化稳定，在一定程度上可以代表整个灯箱的光强变化情况。

| Abstract: | This article through imitating the experiment of the optical properties of lamp boxes, depending on the collection experiments of different fish Aggregation lamp boxes, and using matlab7.0 software building the illuminate distribution model of saury aggregation lights, studies and contrasts the lamp effect of different light illumination in fishing gathering lamp. The results show that: different ground illumination distribution of fishing gathering lamp with distance increasing increases first and decreases; and the change laws of lamp strong values and the illumination distribution are different in different fish collection lights, there is the maximum at the distance of 1 meter, and the light intensity meets: upper light intensity > middle light intensity > lower light intensity; with the light moving from the upper to the lower, the light intensity coefficience of k(L) decreases gradually. It shows that the middle light intensity changes stability and it could represent the changes of the whole lamp boxes in some extent. |
