    摘要: A circuit for detecting the end of life of a fluorescent lamp is provided. In this circuit, a rectifier rectifies a voltage signal detected from a ballast. A phase detector detects the phase of the voltage signal and outputs at least one phase detection signal. A signal separator separates the rectified voltage on a phase basis to generate first and second voltage signals in response to the phase detection signal. A first maximum level detector detects the maximum level of the first voltage signal. A second maximum level detector detects the maximum level of the second voltage signal. A first comparison unit compares the first and second maximum levels and detects whether or not the difference is higher than a predetermined allowable level. A controller determines whether or not the fluorescent lamp is at the end of life in response to the detection from the first comparison unit.

    摘要: A power voltage required to operate the switch control device is generated by using full-wave current rectification voltage generated by rectifying an AC input. A zero cross-point is detected when a full-wave rectification voltage is zero voltage by using the power voltage. A reference signal synchronized to the full-wave rectification voltage is generated by using the detected zero cross-point. A switching operation of a power switch is controlled by comparing a reference signal with current that flows on the power switch.
