Patent ID: 7837345

Claim:
An aquatic light emitting device comprising: a plurality of point light emitting units and a plurality of linear emitting units for connecting the adjacent point light emitting units, wherein each point light emitting unit comprises: a floating member part including 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, a light inlet opening formed on an upper part, and a string connected to a lower surface of the hollow body; a light source part attached to the upper surface of the floating member, having an isolated internal space with an upper light outlet opening provided at the upper surface and a lower light outlet opening provided at the lower surface thereof and a light source comprising a light emitting diode (LED) disposed between the upper light outlet opening and the lower light outlet opening and a light source control circuit contained in the isolated internal space; an upper light emitting body attached on the upper light outlet opening provided at the upper surface of the light source part; and wherein light emitted from the LED is transmitted through the upper light outlet opening and to the light emitting body a power supply part located on the upper surface of the upper light emitting body and including a solar cell; and each 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 and a transparent tube surrounding the optical fiber, wherein one end of the optical fiber is arranged at the light inlet opening of the hollow body, and wherein part of the optical fiber is extended outwards through the junction portion and connected to adjacent the point light emitting unit, and wherein light from the LED is transmitted downward through the lower light outlet opening and to the optical fiber.
