Abstract

See full text

A light driving circuit includes a first and second illuminant unit, a power conversion unit, a first and second switching unit, and a first control unit. The power conversion unit receives an input voltage and converts the input voltage into an output voltage. The first switching unit is coupled to the first illuminant unit. When the first switching unit is turned on, the first illuminant unit is driven by the output voltage to emit light and generate a first output current. The second switching unit is coupled to the second illuminant unit. When the second switching unit is turned on, the second illuminant unit is driven by the output voltage to emit light and generate a second output current. The first control unit controls the first switching unit and the second switching unit to be turned on/off according to the first output current and the second current, respectively.
