1. A light-emitting diode comprising:

  • a light-emitting element;

    a reflecting substrate adjacent which said light-emitting element is disposed;

    a cylindrical reflecting frame disposed directly on said reflecting substrate so as to surround said light-emitting element in a cylindrical interior of said cylindrical reflecting frame;

    a fluorescent material on an inner cylindrical surface of said cylindrical reflecting frame and on a surface of said reflecting substrate beneath said light-emitting element; and

    a transparent material filling the interior of said cylindrical reflecting frame and providing a radiating surface shaped like a concave cone, wherein light emitted from said light-emitting element passes through said fluorescent material to be reflected out of said light emitting diode by said reflecting substrate beneath said light-emitting element and by said inner cylindrical surface of said cylindrical reflecting frame, and is not directly radiated outside of said light-emitting diode.
