Abstract

AN INDUCTIVELY POWERED GAS DISCHARGE LAMP ASSEMBLY HAVING A SECONDARY CIRCUIT WITH STARTER CIRCUITRY THAT PROVIDES PRE-HEATING WHEN POWER IS SUPPLIED TO THE SECONDARY CIRCUIT AT A PRE-HEAT FREQUENCY AND THAT PROVIDES NORMAL OPERATION WHEN POWER IS SUPPLIED TO THE SECONDARY CIRCUIT AT AN OPERATING FREQUENCY. IN ONE EMBODIMENT, THE STARTER CIRCUITRY INCLUDES A PRE-HEAT CAPACITOR CONNECTED BETWEEN THE LAMP ELECTRODES AND AN OPERATING CAPACITOR LOCATED BETWEEN THE SECONDARY COIL AND THE LAMP. THE PRE-HEAT CAPACITOR IS SELECTED SO THAT THE ELECTRICAL FLOW PATH THROUGH THE PRE-HEAT CAPACITOR HAS A LESSER IMPEDANCE THAN THE ELECTRICAL FLOW PATH THROUGH THE GAS OF THE LAMP WHEN POWER IS APPLIED TO THE SECONDARY CIRCUIT AT THE PRE-HEAT FREQUENCY, AND SO THAT THE ELECTRICAL FLOW PATH THROUGH THE PRE-HEAT CAPACITOR HAS A GREATER IMPEDANCE THAN THE ELECTRICAL FLOW PATH THROUGH THE GAS WHEN POWER IS APPLIED THE OPERATING FREQUENCY. THE PRIMARY CIRCUIT MAY INCLUDE A TANK CIRCUIT FOR WHICH THE RESONANT FREQUENCY CAN BE ADJUSTED TO MATCH THE PRE-HEAT FREQUENCY AND THE OPERATING FREQUENCY.
