Abstract
A solid state lighting device may include a power supply and a light emitting device electrically coupled between the power supply and a reference node, with the light emitting device defining a node. A control element may be provided in a current shunting path electrically coupled in parallel with the light emitting device between the power supply and the reference node, with the control element being configured to control a voltage drop across the current shunting path responsive to an electrical signal from the node of the light emitting device. Related methods are also discussed.
