dc.description.abstractLED lamps have experienced growth of usage in artificial lighting because of their high luminous efficiency, long lifetime and resistance to mechanical stresses. Many new manufacturers are starting to produce such lamps, and a part of them do not have enough experience in this particular field. This leads to cheap products that do not meet the productspecific requirements. Due to this reason, a study was initiated in order to analyze standards governing LED light sources, and the simplified and accelerated method for evaluation of lumen maintenance life of LED lamps was proposed. In this paper, the initial results of lamp temperature parameters, the AC/DC converter efficiency analysis and the experimental results of measurement and calculation of lumen maintenance life L70 by applying the proposed technique are discussed.eng
