An Algorithm Analysis of LED Lighting Products Lifetime Based on LM 84
CHEN Zhizhong
Abstract：Based on LM 84's luminaire and light source life test method,the life evaluation was evaluated of the 10 000 h luminous flux and color maintenance of the four products of LED lamp,LED bulb,LED street lamp and par lamp.For each sample,the three function models of exponential function,linear function and logarithmic function were selected to fit together,and the life results under different function models were calculated by using least square method.It is concluded that the calculation of the maintenance life of different kinds of products is not limited to the calculation method of an exponential function model.
