dc.description.abstractMeasurements in electrical and thermal parameters of LED lamps over time have been studied. To get comparable results between lamps, for compliance testing and benchmarking, measurements after stabilization are recommended. Two cases have been tested in the lab: stabilization with sinusoidal voltage waveform and stabilization with distorted voltage waveform both with and without external cooling of the lamp, giving four tests for each LED lamp.The parameters tested were illuminance, active power and temperature of the LED lamps. Based on the results for voltage variations, no significant difference of the parameters studied have been observed. On the other hand, according to the results about environmental thermal variations (emulated using forced ventilation) it is concluded that the illuminance increases with low temperatures, and in addition, in greater percentage than the active power consumed, since the low temperatures would decrease the temperatures of thermal stabilization of LED lamps
