Patent ID: 8546824

Claim:
A light emitting device comprising: a board; a plurality of first light emitting units each of which includes a first light emitting element mounted on the board to emit light having a wavelength of 250 nm to 500 nm and a first fluorescent layer formed on the first light emitting element, the first fluorescent layer including a green phosphor; a plurality of second light emitting units each of which includes a second light emitting element mounted on the board to emit the light having the wavelength of 250 nm to 500 nm and a second fluorescent layer formed on the second light emitting element, the second fluorescent layer including a red phosphor, the second fluorescent layers and the first fluorescent layers being separated in a non-contact manner with air interposed therebetween; and a plurality of third light emitting units each of which includes a third light emitting element mounted on the board to emit the light having the wavelength of 250 nm to 500 nm and a resin layer formed on the third light emitting element, the resin layer including neither a green phosphor nor a red phosphor, the third light emitting units being disposed between the first light emitting units and the second light emitting units, wherein the red phosphor has a composition expressed by equation (2): (M′ 1−x2 Eu x2 ) a1 Si b1 AlO c1 N d1 (2) (in the equation (2), M′ is an element selected from IA group elements, IIA group elements, IIIA group elements, IIIB group elements except Al (Aluminum), rare-earth elements, and IVB group elements, and x2, a1, b1, c1, and d1 satisfy the following relationship: 0 <x 2<1, 0.55 <a 1<0.95, 2.0 <b 1<3.9, 0 <c 1<0.6.
