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： In a control method for supplying power, a first power regulator supplies a first current and an output voltage to a second power regulator and the second power regulator supplies a second current to a load. The method includes: increasing the output voltage and detecting the second current; determining whether the second current suddenly drops as the output voltage increases; when the second current drops, defining a level of the output voltage which corresponds to a starting point of the sudden drop as an upper limit; when the output voltage increases but the second current neither increases nor suddenly drops, defining a level of the output voltage corresponding to a point where the second current stops increasing as a lower limit; and setting the output voltage to be lower than or equal to the upper limit, and higher than or equal to the lower limit.
