Reflection Mode Wavelength Conversion Material for Optical Devices Using Non-Polar or Semipolar Gallium Containing Materials

摘要

An optical device includes an LED overlying a portion of a surface region of a substrate member and a wavelength conversion material within a vicinity of the LED. The device also includes a wavelength selective surface configured to block direct emission of the LED and configured to transmit selected wavelengths of reflected emission caused by an interaction with the wavelength conversion material.
