In this paper, the main failure modes and mechanisms were investigated through some failure analysis cases, based on this, Subsequent 160°C, 170°C and180°C lifetime tests were completed. According to the method of least squares, the degradation model of high power light emitting diodes is obtained. Using the model and ALTA9 software, the extrapolated lifetime of high power light emitting diode at...
