摘要： An ignition system for a high-frequency high-intensity discharge lamp system of a type used for location-lighting during filming or other entertainment venues includes a transformer with a pair of secondary windings, each having a primary winding closely interwound. The secondary windings, which are connected between the steady-state power source and the discharge lamp, are wound for producing opposing magnetic fields with substantial flux cancellation. The primary windings are wound to produce voltage amplification and connected to an ignition circuit adapted to produce high-voltage ignition spikes to turn on the discharge lamp. The system also includes a resonant circuit between the steady-state power source and the transformer. The ignition and resonant circuits are temporarily energized to produce a voltage for igniting the lamp. The advantage of secondary windings with opposing magnetic fields in that a sufficient turns ratio is present to allow the transformer to operate effectively during ignition, while at the same time the opposing magnetic fields result in a low impedance with a reduction in both heat and inductive loss during steady-state operation of the lamp system.

摘要： A hot-restrike ignition system for a high-frequency high-intensity discharge lamp includes a resonant circuit that is connectable across the lamp in parallel with a ballast circuit that is used to provide steady-state current for the lamp. The resonant circuit is temporarily energizable for producing a voltage sufficiently high for hot-restrike ignition of the lamp. The resonant circuit has two parts. The first part provides a voltage waveform with frequency approximating the steady-state voltage frequency and amplitude sufficient when combined with the steady-state voltage to produce glow discharge, and the second part provides a voltage waveform that is lower in repetition rate but of sufficiently high voltage to initiate hot-restrike ignition in the lamp.
