| Abstract |
Light emitting diodes (LED) are a new source for
replacing traditional light sources including under water
illumination. As traditional underwater light sources
operate under a radiative transfer model, the luminous
intensity is dispersed evenly at each emission angle, with
the scattering factors included in the attenuation
coefficient. By contrast, LED light sources are
characterized by being highly directional, causing
underwater luminous energy to vary with different
emission angles. Thus, the traditional theory of
underwater optical transfer becomes inapplicable when
an underwater LED lighting module is designed.
Therefore, to construct an underwater transfer model for
LED light sources, this study employed the average
cosine of the underwater light field, the method for light
scattering probability, the LED luminous intensity
distribution curve (LIDC) and axial luminous intensity.
Afterwards, an underwater LED fish‐attracting lamp was
designed. Experimental results showed that, compared
with the simulation values, the luminous intensity of the
underwater LED lighting module at all emission angles
had a percentage error of less than 10%. |
