Patents by Inventor Moon-Goo Choi

Moon-Goo Choi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Lighting apparatus
    Patent number: 8641244
    Abstract: A lighting apparatus is disclosed. The lighting apparatus is configured such that a light-emitting unit is cooled through movement of air ionized by corona discharge, rather than using a fan that generates noise, resulting in reduced operational noise.
    Type: Grant
    Filed: December 17, 2010
    Date of Patent: February 4, 2014
    Assignee: LG Electronics Inc.
    Inventors: Seong Hun Kwon, Sang Cheon Kim, Moon Goo Choi

  • Optical fiber probe using an electrical potential difference and an optical recorder using the same
    Patent number: 7327665
    Abstract: An optical fiber probe generates an electrical potential difference formed between thin metal layers coated thereon to increase a light transmission rate. The optical fiber probe includes a near-field probe having a core transmitting light incident from an external light source and having a circular cone structure formed on an end of the core, and a cladding coated on a surface of the circular cone structure core to protect the core. The optical fiber probe also includes the thin metal layers coated on the near-field probe, symmetrically disposed on opposite sides of the near-field probe, and spaced-apart from each other to generate the electrical potential difference.
