Abstract:
1. A light emitting device, comprising: a first light emitting diode configured to emit light in an ultraviolet wavelength region; a first molding portion and a second molding portion arranged around the first light emitting diode; a first phosphor arranged around the first light emitting diode, the first phosphor configured to be excited by the light emitted from the first light emitting diode, and the first phosphor configured to emit light comprising a peak wavelength longer than the wavelength of the light emitted from the first light emitting diode; a second phosphor arranged around the first light emitting diode, the second phosphor configured to be excited by the light emitted from the first light emitting diode, and the second phosphor configured to emit light comprising a peak wavelength longer than the wavelength of the light emitted from the first light emitting diode and the peak wavelength of the light emitted from the first phosphor; a third phosphor arranged around the first light emitting diode, the third phosphor configured to be excited by the light emitted from the first light emitting diode, and the third phosphor configured to emit light comprising a peak wavelength longer than the wavelength of the light emitted from the first light emitting diode, the peak wavelength of the light emitted from the first phosphor, and the peak wavelength of the light emitted from the second phosphor; and at least one second light emitting diode configured to emit light comprising a wavelength different from the peak wavelength of the light emitted from the first phosphor, the peak wavelength of the light emitted from the second phosphor, and the peak wavelength of the light emitted from the third phosphor, wherein one of the first phosphor, the second phosphor, and the third phosphor is disposed in the first molding portion, and wherein the other of the first phosphor, the second phosphor, and the third phosphor not disposed in the first molding portion is disposed in the second molding portion.
