Abstract:
A light emitting device includes a light emitting diode (“LED”), a first luminescent material that is configured to emit light having an emission peak in a green wavelength range, and a second luminescent material that is configured to emit narrow-spectrum light having an emission peak in an orange wavelength range. A light output of the light emitting device, which includes a portion of the light emitted by the LED, the light having the emission peak in the green wavelength range, and the light having the emission peak in the orange wavelength range, provides an appearance of white light. Related devices are also discussed.
