Impacts of LED Lighting on Power Quality

Lighting represents a significant portion of global energy use, in some cases approaching 10% of all electrical consumption. Thus, replacing incandescent bulbs with LEDs, which use 75% less energy, offers a viable energy efficiency opportunity. However, because LEDs are non-linear loads they can have significant impacts on power quality. This paper reviews these concerns, and assesses the impact of power quality disturbances on LED lighting.
