Study of the active power behaviour of LED's lamps in uncontrolled operating conditions of environment and supply voltage.

In this report, data and analysis are attached regarding the study of the change of active power over time of LED's lamps operating in the uncontrolled operating conditions of a residential (domestic) environment. Results were obtained showing active power degradation over time for all lamps, the degradation being at a different rate for different lamps and different in different regions of the active power/time characteristics. The duration of the study is over 1300 hours, conducted during the summer season with the quality characteristics of the distribution network 230V/400V. [ABSTRACT FROM AUTHOR]
