    摘要: A control device, which controls a power-converting module that is coupled to a light-emitting component, includes a duration detecting unit and a control signal generator. The duration detecting unit compares the duration of a predetermined logic state of a pulsating input dim control signal with a reference time period. The control signal generator is enabled by the duration detecting unit so as to generate a control signal that enables the power-converting module to generate a drive voltage for driving the light-emitting component when the duration of the predetermined logic state is not longer than the reference time period. The duration detecting unit disables the control signal generator to disable the power-converting module when the duration of the predetermined logic state is longer than the reference time period.

    摘要: A current mirror circuit that comprises a current mirror unit, a feedback unit and an amplifier unit is provided to output low voltage. The current mirror unit has a plurality of connecting ends, wherein one end couples to a current source, and the other end couples to a loading device. The feedback unit couples to the current mirror unit and the amplifier unit. The amplifier unit couples to the current mirror unit to lockup the voltages of the three notes configured in a plurality of MOS transistors of the current mirror unit. By way of the configuration of the present invention, the current mirror unit can detect an accurate current or map out accurately a push controlling current through the electrical characteristic of the amplifier unit and the feedback of the feedback unit.
