Light emitting device with phosphors |
| abstract |
Provided is a light emitting device in which with the general color rendering index Ra and the special color rendering index R9 maintained at high numeric values, the light emission efficiency is prevented from being reduced as much as possible, and the high color rendering and the high efficiency are achieved so as to be usable for general lighting usage. The device includes at least one light emitting element 6 emitting a light having a peak emission wavelength in a near-ultraviolet to blue region, and a phosphor layer 5 containing a green phosphor excited by a primary light emitted from the light emitting element 6 and emitting a light having a peak emission wavelength in a green region, a first red phosphor excited by the primary light and emitting a light having a peak emission wavelength in a red region, and a second red phosphor exited by the primary light and emitting a light having a peak emission wavelength different from that of the first red phosphor in the red region. |
