Features of waterproof power supply:
1. Reliability: Especially the driving power of LED street lamps is at high altitude, so it makes maintenance inconvenient and relatively expensive;
2. High efficiency: LED is an energy-saving product, and the efficiency of the driving power supply should be high. So for the power supply, it is very important to place the structure inside the LED lamp. Because the luminous efficiency of LEDs decreases with the increase of LED temperature, the heat dissipation of LEDs is particularly important. But when the efficiency of the power supply is high, the power loss of the power supply is small, and the heat generated in the LED lamp is also small, so the temperature of the lamp is reduced;
3. Protection function: the lamp is installed outside the lamp, the power supply structure should be waterproof and moisture-proof, and the shell should be light-resistant;
4. Surge protection function: The ability of LED to resist surge is relatively low, especially the ability to resist reverse voltage. So strengthen protection in this regard. Therefore, the LED drive power supply must have the ability to suppress the intrusion of the surge and protect the LED from being damaged.
