On the Adjustment of the Color Temperature of White Light-Emitting Diodes by Femtosecond Laser Patterning
We show that femtosecond (fs) laser microstructuring of light-emitting diode (LED) encapsulates has a high potential for the fine-tuning of the color temperatures of white LED packages. The number of scattering centers that are fabricated within the volume of the encapsulate allows the precise adjus...

Summary: | We show that femtosecond (fs) laser microstructuring of light-emitting diode (LED) encapsulates has a high potential for the fine-tuning of the color temperatures of white LED packages. The number of scattering centers that are fabricated within the volume of the encapsulate allows the precise adjustment of the color temperature of the device to the desired value. This opens possibilities to achieve color reproducibility among individual LED packages with highest accuracy. |
