White light LED device
Light-emitting diode (LED) devices which can produce a uniform white light with a broad emission spectrum and a high color rendering index (CRI) are provided. For example, the emission spectrum of LED devices as described herein may provide more red light and yield a higher CRI light when compared to conventional white LEDs. For some embodiments, the various lights emitted from different layers of the LED device may mix at a light-scattering encapsulation layer and become a uniform white light.
