    摘要： An impulse generator for use with phosphor energizable lamps, e.g. gaseous discharge lamps and electroluminescent lamps, and which eliminates the need of a conventional ballast and starting mechanism. The impulse generator includes a pair of terminals which are adapted to be connected to a conventional source of alternating electrical current with a diode rectifying bridge for rectifying the electrical current. A solid-state circuit switching element is connected to the rectifier and operates in conjunction with a timing means including a resistive capacitive network. Moreover, the solid-state switching element is connected to a primary coil which is coupled to a secondary coil. The secondary coil includes terminals for connection to the lamp. The circuit is operable to generate pulses in a sequence and at time intervals sufficient to maintain energization of the lamp. Thus, the pulses transmitted to the lamp will maintain ignition of the lamp, such that the pulses are applied to the lamp prior to termination of an electric discharge in the lamp. In one of the preferred aspects, the primary and secondary coils form part of a core transformer with the housing sections being separated to create a gap therebetween. In another aspect, the transformer includes an electrically non-conductive spool which holds the windings and with an electrically conductive core located within the non-conductive spool.
