Abstract
Measurements 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
