The point light emitting unit comprises a floating member, a light source part, and a power supply part. The floating member includes a hollow body which has an internal space isolated from the outside so as to give buoyancy, one or more junction portions formed on an outer surface thereof, and has a light inlet opening formed on an upper part, and a string connected to a lower surface of the hollow body. The light source part is attached to the upper surface of the floating member, has an isolated internal space with light outlet openings provided at the upper and lower surfaces thereof, and a light source and a light source control circuit contained in the isolated internal space. The power supply part is located on the upper surface of the light source part and includes a solar cell. The linear light emitting unit comprises at least one optical fiber which is introduced into the hollow body through a hole formed at the junction portion, one end of which is arranged at the light inlet opening of the hollow body, and part of which extends outwards through the junction portion, and is surrounded by a transparent tube.
