Abstract
A lighting apparatus includes at least one light emitting device and a reconfigurable driver circuit configured to drive the at least one light emitting device with an intensity that varies responsive to a dimming signal according to an adjustable mapping of the dimming signal to output of the light emitting device. In some embodiments, the mapping may be configurable using circuit component selection. In further embodiments, the mapping may be provided by a data input.
