In the past four years we have witnessed rapid development in technology and significant market
penetration in many applications for LED systems. New processes and new materials have been
introduced new standards and new testing methods have been developed new driver control and
sensing technologies have been integrated and new and unknown failure modes have also been
presented. In this book Solid State Lighting Reliability Part 2 we invited the experts from
industry and academia to present the latest developments and findings in the LED system
reliability arena. Topics in this book cover the early failures and critical steps in LED
manufacturing advances in reliability testing and standards quality of colour and colour
stability degradation of optical materials and the associated chromaticity maintenance
characterization of thermal interfaces LED solder joint testing and prediction common failure
modes in LED drivers root causes for lumen depreciation corrosion sensitivity of LED packages
reliability management for automotive LEDs and lightning effects on LEDs.This book is a
continuation of Solid State Lighting Reliability: Components to Systems (published in 2013)
which covers reliability aspects ranging from the LED to the total luminaire or system of
luminaires. Together these two books are a full set of reference books for Solid State
Lighting reliability from the performance of the (sub-) components to the total system
regardless its complexity.
