The Problems of Designing LED Driver

The quality of the led driver power directly affects the life of the LED. Therefore, a good led driver must be selected. Firstly, the price of driver Some manufacturers often buy some bad led power supply because of price reasons, so the drive circuit often fails. Second, heat dissipation The LED is a cold lights and the operating temperature cannot exceed the limit. We should design the ent...
