Claims (1)

[Scope of Claim for Utility Model Registration] (1) A lattice-shaped holding frame, a float and anchor member for installing the lattice-shaped holding frame on the water surface or underwater, and a method for drawing a predetermined character on the lattice-shaped holding frame. An optical fiber that is supported by and capable of emitting light from multiple locations along a light propagation path; and a light source device that inputs light to a light input end of the optical fiber led out of a water body. Decorative lighting device for water bodies. (2) The light output ends of a large number of optical fibers are arranged in a matrix dot shape on the water surface or an underwater plane, and the light input ends of each of the optical fibers are
A decorative illumination device for a water body, characterized in that it is provided with a light source device that is arranged outside the water body in a positional relationship corresponding to the matrix dots and that can change and control the light pattern input to each of the light incident ends. (3) a hollow cylindrical light-transmissive float; an anchor member for installing the float at a predetermined position on the water surface or in the water; and an anchor member that is inserted into the hollow part of the float and capable of emitting the light from the light propagation path. A decorative lighting device for a water vehicle, comprising: an optical fiber; and a light source that inputs light to a light input end of the optical fiber installed outside the water area. (4) An optical fiber that can emit light in the middle of the light propagation path is bent into a wire model that has the outline shape of an organism, and installed in a body of water, and the light is inserted into the light input end of the optical fiber placed outside the body of water. A decorative lighting device for a body of water, characterized in that it is provided with an input light source. (5) A group of multiple optical fibers that can emit light midway through the light propagation path are placed in a body of water, and their lower ends are tied together, and their upper ends are opened by their own weight, and the optical fibers are Decorative illumination for a water area, characterized in that a float and an anchor member are provided around the opening area to regulate the opening diameter, and a light source is provided for inputting light to the light incident end of the optical fiber placed outside the water area.
