Degradation Mechanisms in LED Packages

  • Chapter
  • First Online:
Solid State Lighting Reliability

Part of the book series: Solid State Lighting Technology and Application Series ((SSLTA,volume 1))

Abstract

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