摘要： An electronic frequency inverter circuit receives input electrical power at a lower frequency and energizes in a range of higher frequencies a load circuit (36)(37) including gaseous discharge lamps which varies with frequency. First and second switches (30)(31) are operated alternately by a logic circuit mode control (40) such that the switches operate at the high frequency range and the frequency of current in the load circuit varies as the magnitude of said source voltage (10) varies. The load circuit has an impedance such that the peak amplitude of the load current remains substantially constant despite variations in the magnitude of said source voltage to achieve a desirable crest factor for the load current. A high current limit circuit rapidly turns off the switches when excessively high current begins to flow through the switches. Low voltage is supplied in port from the high frequency current. Normal operation is ensured during start-up, for reduced line voltage and for a semiconductor chip embodiment.

摘要： 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.
