摘要： A method and apparatus for protecting a discharge lamp lighting device from damage due to mis-wiring of a source of electrical power to the discharge lamp lighting device. The protection apparatus includes a detector, a comparer and an inhibitor. The detector samples at least one monitor point associated with the discharge lamp lighting device to obtain at least one detection voltage. The comparer compares the at least one detection voltage with a reference voltage. The inhibitor inhibits an operation of the discharge lamp lighting device when the comparer determines that a mis-wiring of the source of electrical power to the discharge lamp lighting device exists.

摘要： An apparatus and method thereof for igniting and operating a high intensity discharge (HID) lamp during an in service life, and powering down the lamp when an end-of-life (EOL) lamp condition is detected. The apparatus and method defines a series of thresholds of lamp voltage asymmetry, or rectification thresholds, and monitors the lamp rectification from ignition through normal operation. The detection scheme is masked off for a predetermined period of time when the lamp is initially started. Thereafter, the rectification threshold of the lamp voltage asymmetry is gradually reduced over time, until a defined minimum rectification threshold level is reached and maintained. The method continuously monitors the lamp voltage and records whenever the lamp voltage asymmetry is higher than the rectification threshold level at any lamp voltage cycle. An EOL lamp condition is determined to exist when a certain number of high asymmetrical cycles occurs in selected total number of lamp voltage cycles during a rolling measurement window.
