Inrush current protection circuit for solid state lighting fixtures

An inrush current protection circuit for a solid state lighting fixture selectively coupled to a power source, the inrush current protection circuit comprising:

• a current limiting device;
• and
• a relay switch coupled in parallel with the current limiting device, the relay switch configured in a first state when the solid state lighting fixture draws an inrush current from the power source, the relay switch configured in a second state when the solid state lighting fixture draws a steady-state current from the power source,
• one or more surge protection devices comprising:
• a first surge protection device coupled between a first conductor coupling the solid state lighting fixture to the power source and a second conductor coupling the solid state lighting fixture to the power source;
• a second surge protection device coupled between the first conductor and a third conductor coupling the solid state lighting fixture to ground;
• and
• a third surge protection device coupled between the second conductor and the third conductor,
• wherein when the relay switch is configured in the first state, the inrush current is provided to the current limiting device, and
• wherein when the relay switch is configured in the second state, the steady-state current bypasses the current limiting device.
