White light emitting device comprising a plurality of light emitting diodes with different peak emission wavelengths and a wavelength converter

A light emitting device, comprising:

• at least two light emitting diodes comprising a first light emitting diode and a second light emitting diode, the first light emitting diode to emit primary light having a first peak emission wavelength in a wavelength range of ultraviolet above 360 nm and below 380 nm, the second light emitting diode to emit primary light having a second peak emission wavelength in a wavelength range of blue light, and the first peak emission wavelength being different from the second peak emission wavelength;
• and
• a wavelength converter to convert the primary light of the first peak emission wavelength and the second peak emission wavelength into secondary light in a visible light wavelength range,
• wherein the light emitting device emits white light comprising the primary light of the second peak emission wavelength and the secondary light converted from the primary light of the first peak emission wavelength and the primary light of the second peak emission wavelength by the wavelength converter.
