ABSTRACT:
A device and method for emitting output light utilizes both quantum dots and non-quantum fluorescent material to convert at least some of the original light emitted from a light source of the device to longer wavelength light to change the color characteristics of the output light. The device can be used to produce broad-spectrum color light, such as white light.
