The core of the LED lamp driver is the IC, and the quality of the IC directly affects the entire LED lamp driver. Judging by the transformer, the transformer determines the power and temperature resistance, and is responsible for completing the conversion between alternating current, magnetic energy and direct current. The overload of energy will saturate the machine.

1. Judging by electrolytic capacitors and chip ceramic capacitors;

2. Judging by the circuit design and welding process of the power supply products;

3. Judging by batch testing aging racks and high temperature aging rooms of power products;

4. Through the aging of the entire batch of power supplies and the high-temperature random inspection of the high-temperature room, the quality stability of the power supply and whether the materials have potential safety hazards are detected;

5. In addition, there are some broken symptoms: completely off: a certain lamp bead is broken; the power supply may also be broken. Flashing and flashing: the gold wire of the lamp bead is soldered, resulting in poor contact; the power supply is unstable.
