摘要： The configurations of an end of lamp life protection circuit for a ballast and a method thereof are provided in the present invention. The proposed circuit includes a voltage-dividing circuit receiving an input voltage and outputting a first and a second divided voltages and a switch apparatus raising the first divided voltage when the second divided voltage is less than a first pre-determined threshold value and turning off the ballast when the first divided voltage is higher than a second pre-determined threshold value.

摘要： A compensating device is used for providing current compensation of an IC when operating in the high-voltage. The current compensating device includes a detecting unit, a rectifier, a filtering unit and a switching unit. The detecting unit electrically connected to an AC voltage. The rectifier is electrically connected to the detecting unit. The filtering unit is electrically connected to the rectifier. The switching unit is electrically connected to the filtering unit. The switching unit is conducted and provides a current to the IC when the AC voltage is above a predetermined voltage.
