High brightness illumination based on laser light diffusion with mie scattering

Azarifar, Mohammad; Cengiz, Ceren; Ocaksönmez, Kerem; Onal, A.; Nizamoglu, S.; Arık, Mehmet (ASME, 2022)

Limited luminous flux per wafer area of light emitting diodes (LEDs) for high power solid state illumination causes some packaging real estate issues. This problem can be tackled with laser diodes (LDs). At high current ...
Machine learning to predict junction temperature based on optical characteristics in solid-state lighting devices: A test on WLEDs

Azarifar, Mohammad; Ocaksönmez, Kerem; Cengiz, Ceren; Aydoğan, Reyhan; Arık, Mehmet (MDPI, 2022-08)

While junction temperature control is an indispensable part of having reliable solid-state lighting, there is no direct method to measure its quantity. Among various methods, temperature-sensitive optical parameter-based ...
