<P>PROBLEM TO BE SOLVED: To provide a light emitting device capable of improving a color mixing property to suppress color unevenness, and also improving optical output. <P>SOLUTION: The light emitting device includes a plurality of kind of LED chips 11 to 13 emitting light beams differing in main wavelengths from one another, a mounting substrate 20 having the plurality of kind of LED chips 11 to 13 mounted on one surface side, and a lens portion (transparent body) 30 covering the plurality of kind of LED chips 11 to 13 on the one surface side of the mounting substrate 20. The lens portion 30 is provided with many metal nanostructures 40 which have surface plasmons 50 excited with the light beams emitted by the respective LED chips 11 to 13 to cause surface plasmon resonance. <P>COPYRIGHT: (C)2010,JPO&INPIT |
