Abstract
A light-emitting element control system is described comprising a series connection of one or more LEE units, each comprising one or more LEEs and a unit activation module. The unit activation module associated with a LEE unit is configured to controllably activate, in response to a unit activation control signal, the one or more LEEs in that unit. A control module is operatively coupled to each of the unit activation modules and configured to provide the unit activation control signals thereto. A converting module is operatively coupled to the series connection of LEE units, adapted for connection to a source of power and configured to provide a drive current to the LEE units.
