摘要:
A control system for a feedback controlled LED driving circuit, which includes a valley detect regulator unit and a control and feedback unit. The valley detect regulator unit detects a sine-like DC voltage input by a rectification unit, and stores the electric energy in the storage capacitor when the input voltage is lower than a preset valley voltage. The stored electric energy converted into the system required voltage by a system power supply unit. The control and feedback unit electrically connect to the feedback controlled LED driving circuit, providing PFC, step dimming or color temperature adjustment for driving the LED light-emitting element and detecting a feedback signal of the LED driver circuit for controlling an output current of the LED driver circuit or providing protective measures.

摘要:
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.
