<P>PROBLEM TO BE SOLVED: To provide a light-emitting device capable of suppressing reabsorption among phosphors and realizing excellent luminous efficiency. <P>SOLUTION: The light-emitting device comprises: a substrate; a first light-emitting device, which is mounted on the substrate, to emit light whose wavelengths are from 250 nm to 500 nm; a plurality of first light-emitting parts which are formed on the first light-emitting device and have a first phosphor layer containing a green phosphor; a second light-emitting device, which is mounted on the substrate, to emit light whose wavelengths are from 250 nm to 500 nm; a plurality of second light-emitting parts which are formed on the second light-emitting device and have a second phosphor layer containing a red phosphor; a third light-emitting device, which is mounted on the substrate between the first light-emitting device and the second light-emitting device, to emit light whose wavelengths are from 250 nm to 500 nm; and a third light-emitting part which is formed on the third light-emitting device and has a resin layer containing neither a green phosphor nor a red phosphor. The first phosphor layer and the second phosphor layer are separated in a noncontact state with gas sandwiched therebetween. <P>COPYRIGHT: (C)2012,JPO&INPIT |
