The paper is to estimate lifetime of LED packages and modules using general lighting by testing data. The recently, Aging time is about 100 hours, in where established by law of LED packages and modules for general lighting(KS C 7651, KS C 7652 and KS C 7653). But as estimating lifetime of LED packages and modules, initial time is very important, because lifetime of LED packages and modules is different by initial time. Therefore, the paper aids companies to analysis test data by themselves.
