Abstract

A device and method for emitting output light utilizes multiple light sources to produce original light having different peak wavelengths. A first light source of the device is configured to generate first light having a peak wavelength in the blue wavelength range, while a second light source of the device is configured to generate second light having a peak wavelength in the red wavelength range. Some of the original light emitted from at least the first light source is converted into light having a peak wavelength longer than the peak wavelength of the original light using a photoluminescent material to produce the output light.
