(57) [Abstract] The present invention relates to dimmable compact fluorescent lamp more triac with a low power factor. Also in the low dimming levels, the power feedback circuit coupled between the input and output stages of the lamp ballast, causing sufficient current required to maintain ...
Power Factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA). Apparent power, also known as demand, measures the amount of power used to run machinery and equipment during a certain period. It is found by multiplying ...
