Abstract
A circuit for altering a level of impedance presented to a power supply including a power supply line includes an energy dissipating circuit, a detection circuit configured to generate a control signal indicative of a power consumption level in a load circuit coupled to the power supply line, and an activation circuit configured to controllably couple the energy dissipating circuit to the power supply line in response to the control signal. Methods of operating a solid state lighting apparatus including a power supply and a solid state lighting device coupled to the power supply include detecting a level of power consumption by the solid state lighting device, and coupling an energy dissipating circuit to the power supply in response to the level of power consumption by the solid state lighting device falling below a threshold level.
