<P>PROBLEM TO BE SOLVED: To provide an LED lighting system with a high-luminance and large-output light source of a single flat-face light emission type capable of controlling light distribution reaching middle distance and long distance. <P>SOLUTION: The lighting system is provided with a metal board, a circuit board, a plurality of bare-chip state light-emitting elements directly jointed to a surface of the metal board, a sealing frame adhering to the surface of the metal board and surrounding a periphery of the plurality of light-emitting elements wiring-connected to a whole or a part of the circuit board, and a sealing material sealing the light-emitting elements while being in contact with the same inside the sealing frame. The sealing material is to be a transparent or translucent material capable of containing a fluorescer, and at the same time, with its top face of a flat-face shape, converts light emitted by the light-emitting elements into flat-face single emission light. <P>COPYRIGHT: (C)2013,JPO&INPIT |
