Abstract: A control device including a first switch, a control unit and a second switch is provided. When the first switch is turned on, a power signal generated by a power supply is transmitted to a lighting load via the first switch. The brightness of the lighting load is gradually increased or reduced as time increases. When the first switch is turned on, the control unit executes a countdown according to a time value. Upon finishing the countdown, the control unit generates a trigger signal and simultaneously the brightness of the lighting load is at a set value. When receiving the trigger signal, the second switch stops transmitting the power signal from the first switch to the lighting load at first and then transmits the power signal from the first switch to the lighting load such that the brightness of the lighting load keeps at the set value.
