INRUSH CURRENT PROTECTION CIRCUIT FOR SOLID STATE LIGHTING FIXTURES

Abstract:

An inrush current protection circuit for a solid state lighting fixture is provided. The inrush current protection circuit includes one or more current limiting devices and one or more switching devices coupled in parallel with the one or more current limiting devices. The one or more switching devices are configured in a first state when the solid state lighting fixture draws an inrush current from a power source. The inrush current is provided to the one or more current limiting devices when the one or more switching devices are in the first state. The one or more switching devices are configured in a second state when the solid state lighting fixture draws a steady-state current from the power source. The steady-state current bypasses the one or more current limiting devices when the one or more switching devices are in the second state.
