| Abstract: | A new method for the analysis of life data of environment-protecting and energy-saved lights based on Weibull-distributing by improved maximal likelihood estimate put forward.This method uses the life data of environment-protecting and energy-saving lights gained by accelerated life testing.It realizes equivalent-conversion of experimental time under the condition of high stress by using the method of statistics and the model of Weibull-distributing.The life data of environment-protecting and energy-saving lights by using improved maximal likelihood estimate is availability. |
