Research of reliability of light emitting diodes to mechanical and climatic loads

This paper discusses the development of object to perform specified functions, preserving in time the values of established performance indicators within specified limits that correspond to specified modes and conditions of use. The dependence of the failure rate on this site, which is the most important for the ECO, is usually described by a logarithmically normal law, for which the failure rate is not constant over time. When statistically predicting the reliability characteristics of an ECO using models of the development of degradation of parameters from time and load, failures are divided into two types: partial and complete.
