Establishment of transmission model for broad-spectrum artificial light in case 1 water
Abstract:
A new simulation model for light transmission of broad-spectrum artificial light in case 1 water is introduced in this paper. The model simulates spectrum changes of fishing lamps due to absorption and scattering of seawater. According to underwater spectrum changes, this model restores the light field generated by fishing lamps and demonstrates the distribution of visual stimuli to marine organisms. The accuracy of the transmission model is verified by comparing it with experimental data. In addition, by comparing the simulation results of light transmission models of different fishing lamps in seawater of various fishing grounds, we investigate why current light-emitting diode (LED) lights are not as effective as metal halide (MH) lamps for light fishing. Lastly, suggestions for future optimization of LED fishing lamps in terms of light distribution design and spectrum configuration are provided.
