不同光色的LED光源在养殖池内辐照度的测量与研究

Measurement and study on irradiance of LED light source with different light colors in aquiculture pond

该文设计了以红光、黄光、绿光、蓝光和白光5种LED光源作为光谱处理组,对海水养殖池内不同水面高度水面上以及确定水面高度以下不同水深的辐照度进行测量,得出光在室内海水养殖池中的传播规律,为实现室内水产养殖光环境标准化调控提供科学的数据参考。结果显示,5种不同LED光谱处理组在养殖池水面以上具有较大的光能量衰减,蓝光在空气中的透光率最低,白光透光率最高;在养殖池内海水的透光率随深度的增加呈下降趋势,不同波长光源间的变化趋势存在差异,在水中当透光水深为30 cm时,白光透光率最低,绿光的透光率最大。

In this paper,five kinds of LED light sources such as red light,yellow light,green light,blue light and white light,are used as the spectrum processing group to measure the irradiance of different water surface heights above and below the water surface heights.The propagation law of light in indoor agriculture pond is obtained,which provides a scientific data reference for realizing the standardization control of light environment in indoor industrial aquaculture.The results show that five different LED spectral treatment groups have great light energy attenuation above the water surface,blue light has the lowest light transmittance in air and white light transmittance is the highest.In the aquaculture pond,the light transmittance of seawater decreases with the increase of depth,and there are differences among light sources with different wavelengths,when the water depth is 30.00 cm,the transmittance of green light is the highest,and that of white light is the lowest.
