LIGHT BEAM FOR FARMING FISH.

摘要

PURPOSE:To radiate light into water and grow algae, etc., by putting a light guide radiating light introduced into the end part from the peripheral surfaces thereof towards the outside in a transparent vessel, placing the transparent vessel in a semitransparent vessel and arranging the semitransparent vessel in water. CONSTITUTION:Light with wavelengths suitable for breeding algae, etc., is transmitted to a light guide 1 through a light guide cable 11 and the light radiated from the peripheral surfaces of the light guide 1 towards the outside thereof is irradiated into water through a transparent vessel 2 and a semitransparent one 4. The vessel 2 accommodates the light guide 1 in a sealed state and the vessel 4 accommodates the vessel 2 in a sealed state.
