At present, LEDs are driven by DC, so you need a led drivers for lighting that converts AC mains power into a suitable DC power for LEDs. Then, when selecting and designing led drivers for lighting, the following points should be considered:

1.High reliability

Especially like the driving power of LED street lights, installed at high altitude, it is inconvenient to maintain, and the maintenance cost is also high.

2.High-efficiency

LEDs are energy-saving products, and the efficiency of the led power supplies should be high. It is particularly important for the structure where the power supply is installed in the lamp. Because the luminous efficiency of the LED decreases with the increase of the LED temperature, the heat dissipation of the LED is very important. The led power supplies has high efficiency, its power consumption is small, and the heat generated in the lamp is small, which is beneficial to delaying the light decay of the LED.

3.High power factor

The power factor is the requirement of the grid on the load. Generally, there are no mandatory indicators for electrical appliances below 70 watts. Although the power factor of a single electrical appliance with low power is lower, it has little effect on the power grid, but if everyone lights the lights at night, the similar loads are too concentrated, which will cause serious pollution to the power grid.

4.Protection function:

In addition to the conventional protection function of the led power supplies, it is best to add negative feedback of LED temperature to the constant current output to prevent the LED temperature from being too high.

5. In terms of protection, the lamp is externally installed, the power supply structure should be waterproof and moisture-proof, and the shell should be light-resistant.
