General features of led power supply

  • High efficiency: LED is an energy saving product, and the led power supply is more efficient.

    Because the luminous efficiency of LED decreases with the increase of LED temperature, the heat       dissipation of LED is very important. The power supply has high efficiency, it consumes less         power, generates less heat in the lamp, and reduces the temperature rise. It is beneficial to         delay the LED's optical fading.

  • Surge protection: as the name implies, the peak value exceeding the stable value is instantaneous. It includes surge voltage and surge current. Essentially, a surge is a violent pulse that takes place in just a few millionths of a second. The possible reasons for bow surge are: lightning, power load input and removal, short circuit, power switching, inductive load input and removal. The ability of LED to resist surge is poor, especially the ability to resist reverse voltage. Some LED lights are installed outdoors, such as LED street lamps. Due to the load on the power grid and the induction of lightning strikes, all kinds of surges will be intruded from the power grid system, some of which will lead to LED damage. Therefore, the LED drive power supply should have the ability to suppress the intrusion of waves and protect the LED from damage.
