  • Aquarium lighting system
    Patent number: 5211469
    Abstract: An aquarium lighting system for underwater illumination of an aquarium tank. The light sources each include an elongated insulated wire having a light emitting diode on one end. A water impervious encapsulating layer of material extends over the LED lens and preferably seals and electrically insulates the connection between the elongated wire and the light emitting diode. The wire insulation is both waterproof and watertight. The plug has an opening extending therethrough which cooperates with an attachment mechanism such as a tie wrap or a suction cup to facilitate attaching the light emitting diode to either an object within the tank or the tank walls. A decorative aquarium volcano and display stand also are shown.
