LIGHT EMITTING DEVICE
First Claim
1. 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.
