<P>PROBLEM TO BE SOLVED: To provide a light-emitting device that can further obtain properties other than high color rendering properties. <P>SOLUTION: The light-emitting device 10 includes: an LED light source 12 for emitting blue light having a peak wavelength at a luminous wavelength of 420 to 480 nm; and a plurality of phosphors 13 and 14 for emitting a light subjected to wavelength conversion by being excited with the light emission of the LED light source 12. One of phosphors 13 and 14 contains a blue-green light from MSi<SB POS="POST">2</SB>(O, X)<SB POS="POST">2</SB>N<SB POS="POST">2</SB>:Eu(Sr, Ba, Ca, X=Cl, Br). White light thus obtained has a spectrum of 480 to 520 nm and a peak wavelength. <P>COPYRIGHT: (C)2013,JPO&INPIT |
