The energy efficiency of LED lighting applications needs to be considered in conjunction with power output. The US Energy Star solid-state lighting specification specifies the energy efficiency of the lighting fixture level, but does not address the energy efficiency requirements of individual LED drivers . As mentioned earlier, LED applications using AC-DC power supplies can use a two-stage distributed topology, so they may be powered by an external AC-DC adapter. The "Energy Star" does include specifications for single-output external power supplies. The 2.0 version of the external power supply specification came into effect in November 2008, requiring a minimum energy efficiency of 87% in the standard operating mode and a minimum energy efficiency of 86 in the low-voltage operating mode. %; In this specification, PFC is required only when the power is greater than 100 W.
In LED applications using AC-DC power supplies, providing higher AC-DC conversion energy efficiency involves trade-offs between cost, size, performance specifications, and energy efficiency. For example, using higher quality components and lower on-resistance (RDSon) can reduce losses and improve energy efficiency; lowering the switching frequency generally improves energy efficiency, but increases system size. New topologies such as resonance provide greater energy efficiency, but also increase the complexity of the design and components. If we limit the design to a narrower power and voltage range, it can help optimize energy efficiency.
