POWER QUALITY DURING AGEING OF LED LAMPS

In this paper a large-scale experiment is described where a total of 1080 LED lamps are being subjected to six different voltage profiles during 6500 hours while their performance in terms of current quality is being monitored. A link between voltage quality (impact from the grid) and performance of LED lamps is studied as well as the current quality aspects of the LED lamp (impact on the grid) during the aging process.
