5. Surge protection: The ability of LEDs to resist surges is relatively poor, especially the ability to resist reverse voltage. It is also important to strengthen protection in this area. Some LED lights are installed outdoors, such as LED street lights. Due to the activation of the grid load and the induction of lightning strikes, various surges will invade from the grid system, and some surges will cause damage to the LED. Therefore, the LED drive power supply must have the ability to suppress the intrusion of surges and protect the LED from damage.
6. Protection function: In addition to the conventional protection function of the power supply, it is best to add negative feedback of LED temperature to the constant current output to prevent the LED temperature from being too high.
7. In terms of protection: the external installation type of the lamp, the power supply structure should be waterproof and moisture-proof, and the shell should be resistant to sunlight.
8. The life of the driving power supply should be matched with the life of the LED.
9. To meet the requirements of safety regulations and electromagnetic compatibility.
