LED lighting reliability from a failure perspective

Incredible long-life makes LED lighting systems a good long-term investment The higher capital cost is justified as there is long-term energy and maintenance cost savings. Operational requirements and materials used in manufacturing a of LEDs make then-failures distinctive compared to other microelectronics devices. Significant effort has gone into understanding of the failure modes and mechanisms and reliability of LED lighting. Although still very incomplete, our knowledge of the reliability issues relevant to LED lighting is increasing. This paper provides an overview of LED lighting failure modes and mechanisms that are commonly encountered. It focuses on the reliability issues of LED lighting.
