Project Objective

The primary objectives of the proposed work will be to develop and validate a reliability model and accelerated life testing (ALT) methodologies for predicting the lifetime of integrated solid-state lighting (SSL) luminaires. This study will examine likely failure modes for SSL luminaires, including abrupt failure, excessive lumen depreciation, unacceptable color shifts, and increased power consumption. Data on the relative distribution of these failure modes will be acquired through extensive accelerated life tests (ALT) such as the Hammer Test and temperature/humidity methods. These data will be used to build models of the aging behavior of key luminaire optical and electrical components.
