Abstract: The present invention discloses a LED controlling driver comprising light emitting diodes and a detection-control module and a power supply unit in addition to the light source. The detection-control module includes a power/blinking control unit and a LED driver IC. The power supply unit outputs power to the light source and the detection-control module and provides different switching information so that the LED drive unit of the detection-control module is controlled by power/blinking control signals. Further, a power switch enables the power supply unit to output the corresponding switching information to the detection-control module based on switching actions inputted by a user so that the user only needs to simply switch the power switch to achieve the goal of switching power levels or blinking states of the LED.
