LED has many advantages, such as environmental protection, energy saving, small size, long life, etc., which will gradually replace traditional fluorescent lamps and incandescent lamps in general lighting in the future. The performance of the driving power supply is the key to ensuring the overall performance of the LED. Therefore, it is necessary to ensure that the LED driving power supply has the advantages of small size, long life, and high reliability. The driving of LED has the following research hotspots:

1. Improve the life of the mini drive power supply

One of the important advantages of LEDs is their long service life, about 30,000 to 100,000 hours. The traditional LED driving power supply contains electrolytic capacitors, and the lifespan of the electrolytic capacitors is relatively short, about 5,000 hours. This is the main reason that restricts the life of the LED driving power supply. Therefore, electrolytic capacitors should not be used in the LED driving power supply as much as possible.

2. Improve the input power factor of the drive power supply

3.  produce slim size drive power supply

The LED itself is relatively small, which is very beneficial for portable products. The LED drive power supply should also be as small as possible, so that it can be smoothly installed in the LED lamp holder. In the design process, the volume of the drive power supply should be reduced as much as possible.

4. Improve the reliability of the drive power

During the working process of the LED, non-human factors such as high temperature and aging of the device can cause fatal damage to the LED body. Therefore, protection circuits such as overvoltage protection and overcurrent protection should be added to the LED drive power supply to deal with accidents and ensure the safe operation of the LED body.
