Abstract

An LED driver includes a controller configured to detect toggles of a switch that controls whether electrical power is provided to the LED driver. The controller is further configured to determine whether a toggle sequence of the switch matches an operation mode sequence. The toggle sequence of the switch includes a sequence of one or more toggles of the toggles of the switch that the controller detects. The controller is also configured to change a setting of the LED driver based on whether the toggle sequence of the switch matches the operation mode sequence.
