Abstract
A luminaire can comprise an electronic circuit, such as an LED driver or electronic ballast. A surge protection device in the current path between a power supply and the luminaire components can be configured to protect the electronic circuitry by absorbing and/or redirecting energy of a surge by switching into a low-impedance state while maintaining the protected circuitry (including its internal protective components, if any) in a high-impedance state. The surge protection device can comprise a MOV stage and a filter stage, for example. The surge protection device can be configured as a replaceable module, with the luminaire including an assembly designed to receive the module and allow for easy replacement over the useful life of the other components. Use of fuses or thermal components may cause the surge protection device to interrupt power flow if protection is lost due to internal failure, indicating when module replacement is needed.
