Abstract

This report investigates the electro-optical and thermodynamic mechanisms of light-emitting diodes (LEDs) under varying thermal conditions. It focuses on the impact of elevated junction temperatures (Tj) on LED emission spectra across different semiconductor materials, including Indium Gallium Nitride (InGaN) and Aluminum Gallium Indium Phosphide (AlGaInP). Utilizing a high-resolution optical spectrometer and a thermoelectric temperature control stage, the study finds that higher operating temperatures lead to a red shift in peak emission wavelengths and increased full-width at half-maximum, while reducing optical output power and internal quantum efficiency due to the activation of non-radiative recombination paths. Additionally, white LEDs experience significant thermal quenching effects, affecting color temperature and gamut. The study concludes with recommendations for high-efficiency micro-channel heat sinks and dual-junction measurement strategies to enhance reliability in optoelectronic systems.
