摘要: Lumen depreciation is one of the major failure modes in light-emitting diode (LED) systems. It originated from degradation different components within package, being LED device or chip, driver, and optical materials (including phosphorous layer). This chapter describes state art mechanism for these how they contribute to lumen package as a whole.
