Patent abstract

An LED lighting driver has a switched mode power supply which generates an auxiliary power supply. The auxiliary power supply has a dummy load, and a control circuit for controlling the connection of the dummy load in parallel with the auxiliary load in dependence on the current drawn by the auxiliary load. In this way, a current drawn by the auxiliary load is made more stable so that effects of auxiliary supply fluctuations on the light output are reduced.
