| 摘 要： | 为了解决平板式LED集鱼灯安装不合理的现状,使得LED集鱼灯光能得到有效利用,提高诱、集鱼效果,实验分析了海面的菲涅耳现象,利用光学的临界条件原理推导出了菲涅尔公式,并利用透射率和折射率的定义式,得到光通过两个不同介质分界面时透射率和折射率的各分量与入射角的关系式,进而利用MATLAB仿真了光在通过海面时透射率和反射率随入射角改变而变化的函数图像。结果显示,透射光强最大时的入射角为53.6°,可以此入射角指导LED集鱼灯在渔船上的安装。对于平板式LED集鱼灯,安装角度可取36.4°;对于三列式LED集鱼灯,安装角度可取23.6°,相邻两列LED集鱼灯的夹角为160°。

| Abstract: | LED lamp is a new type of light source which was introduced to light fishing, and its reasonable arrangement on boat will directly relate to the effect of luring fish.The article analyzes the Fresnel Phenomenon.The formula of relationship between each component of transmittivity and refractive indexs and angle of incidence when light goes through two different interfaces of medium can be get through the Fresnel's formula that is deduced from the principle of optical critical condition and the definition formula of transmittivity and refraction.And then, we can get the functional images that the transmittivity and refraction changed because of the variation of incidence angle when light passes through the sea surface by making use of MATLAB.The incidence when intensity of transmission beam reaches the maximum is 53.6°.This incidence angle can guide the installation of LED fish aggregation lamp in fishing boat.But the incidence angle could be changed to 36.4° for flat plate type LED fish aggregation lamp and could be changed to 23.6° for the three columns type of LED fish aggregation lamp.The included angle between two columns of LED fish aggregation lamps is 160°. |
