Abstract
An electrical luminaire receives an AC supply as well as an auxiliary power supply. A power converter converts the AC power to supply a lighting element. A power factor associated with the AC supply is used as a control input for selecting an amount of power to be supplied from the two supplies. This enables the overall power factor to be controlled, for example to avoid financial penalties associated with the use of the AC supply with low power factor.
