LIGHT EMITTING DIODE WITH BONDED SEMICONDUCTOR WAVELENGTH CONVERTER
摘要:
An electroluminescent device emits light at a pump wavelength. A first photoluminescent element covers first and second regions of the electroluminescent device and converts at least some of the pump light from the first region of the electroluminescent device to light at a first wavelength. A second photoluminescent element covers the second region of the electroluminescent device without covering the first region of the electroluminescent device and converts at least some of the light of the pump wavelength to light at a second wavelength different from the first wavelength. In some embodiments the first and second photoluminescent elements convert substantially all of the pump light incident from the first and second regions of the electroluminescent device respectively. An etch-stop layer may separate the first and second photoluminescent elements.
