摘要： The present invention provides a light emitting device, comprising a first light emitting diode for emitting light in an ultraviolet wavelength region; at least one phosphor arranged around the first light emitting diode and excited by the light emitted from the first light emitting diode to emit light having a peak wavelength longer than the wavelength of the light emitted from the first light emitting diode; and at least one second light emitting diode for emitting light having a wavelength different from the peak wavelength of the light emitted from the phosphor.
