Abstract
A device can include multiple light loads, where each light load includes at least one light source. The device can also include multiple switches coupled to the light loads. The device can further include a controller coupled to the switches, where the controller actively operates the switches multiple times within each cycle to control delivery of power to the light loads. Active operation of the switches by the controller is performed on a dynamic schedule, where the dynamic schedule is based on multiple environmental conditions, and where the controller bypasses a forward voltage of the light loads when actively operating the switches.
