Method and apparatus for disabling sodium ignitor upon failure of discharge lamp |
摘要 |
An ignitor disabling apparatus is provided to reliably and automatically disable a universal sodium ignitor with hot re-strike capability, or a 120 Hz pulse capability. The ignitor is configured to disable the ignitor portion of a HID lamp if the lamp fails to start. Timing operation of the disabling circuit is achieved using a power supply that ramps to a steady state to provide triggering of a timer circuit. A normally closed, solid state gating device is used for disabling the ignitor to minimize sparks. The disabling apparatus can be retrofit into an existing universal sodium ignitor.
