Abstract
An ignition scheme for starting a high intensity discharge lamp requiring energy in the form of ignition pulses to be provided to the lamp prior to and substantially throughout the glow load of the lamp. An ignitor includes a bilateral switching device such as, but not limited to, a SIDAC having a breakover voltage corresponding to the lamp voltage during the lamp glow mode. The ignition scheme substantially eliminates the lamp remaining in its glow mode for a prolonged period of time thereby minimizing the possibility of lamp destruction from damage to the lamp electrodes.
