Remote Online Two-Step Stress Lifetime Acceleration Test System for Ultraviolet Light-Emitting Diodes
See t.ly/jlkP — Ultraviolet light-emitting diodes (UV LEDs) have been widely applied in various fields, such as sewage treatment, sterilization and disinfection medical treatment. However, the remained problems of UV LEDs mainly concern poor photoelectric stability, low efficiency, safety protection, and among others. In order to evaluate and predict the stability and lifetime of UV LEDs safely and efficiently, a comprehensive UV LEDs two-step aging test system has been designed in this work. Two steps of different temperature stresses with total aging time up to 720 hours are applied to UV LEDs. The junction temperature derived from spectroscopy has…
