Paper Abstract

For both high conversion efficiency and thermal stability, glass-based phosphor-converted white light-emitting diodes (GBPC-WLEDs) were packaged for optic characterization study. Fabricated by flip chip, glass based PC-WLEDs were found Tj dramatically decreased, and emission intensity eminently raised up. If driven by large electric current, such samples would have even lower Tj 36°C. These characteristics will significantly improve thermal stability and lifetime of the LED packaging modules. In addition to high optical quality and low manufacture cost, such better thermal stability of glass phosphor layer may be beneficial for public policy of mass replacement of street lights with solid-state lighting LED as one of many applications requiring high-power and high reliability.
