1. High reliability and unique driving power supply, like LED street lights, installed at a high place, not easy to repair, and the cost of repair is also high.

2. High power LED is an energy-saving product, and the power of the driving power supply should be high. The structure of the power supply installed inside the lighting is particularly important. Due to the fact that the luminous power of LED decreases with the increase of LED temperature, the heat dissipation of LED is quite important. The power of the power supply is high, and its loss of power is small. As a result, the fever inside the lighting fixtures is small, which reduces the temperature rise of the lighting fixtures. It is beneficial for delaying the light decay of LEDs.

3. High power factor Power factor is the requirement of the power grid for the load. Generally, there are no mandatory indicators for electrical appliances below 70 watts. Although the lower power factor of individual appliances with low power has little impact on the power grid, when people turn on lights at night and the same type of load is too concentrated, it will cause significant pollution to the power grid.
