4. Lighting
4.1 Lamp operation
Following the EuP 2005/32/EC European directive on ecodesign requirements aimed at significantly reducing CO 2 emissions, incandescent lamps with wattages above 25 W will gradually disappear. New lighting solutions have emerged, including compact fluorescent lamps (CFLs) and GaN light-emitting diode (LED) lamps. Unlike incandescent lamps, current consumption is no longer sinusoidal. Current distortion is caused by the AC/DC converter built into these new lamps. LED lamps generally use a flyback DC/DC converter, while CFL lamps incorporate a ballast-type converter. What both converters have in common is the capacitive-filtering bridge rectifier, involving a pulse-shaped current draw. Figure
