The led driver power supply can be converted to a specific voltage and current to drive the LEDs to illuminate. The input led power supply usually includes alternating current, low voltage direct current, high voltage direct current, and the like. However, the output led power supply can change the voltage of the constant current supply as the forward voltage drop of the LED changes.

General principle

Firstly, depending on the characteristics of the LED current and voltage, it is ideal to use a constant current LED driver to avoid variations in LED voltage and current. At the same time, constant voltage stabilizes the brightness of the LED.

Secondly, when using led power supply, it should reduce heat generation and design a good heat dissipation system.

Thirdly, in order to ensure the service life of LED products, we should control the operating temperature of LED products.

Fourthly, high reliability

LED products are mainly composed of LED chips, power supplies, heat-dissipating housings, and control circuits. LED power determines the quality of LED products. The led driver power supply is installed at a high altitude, the maintenance is inconvenient, and the repair cost is too high.

Fifthly, high efficiency

LEDs are energy efficient products. The LED driver power is very efficient. The led power supply installed in the luminaire is very important. The led driver power supply efficiency is high, the power consumption is low, the heat value is low, and the illumination temperature is low.

Sixth, constant current drive

In order to meet the volt characteristics of the LED, the LED power supply should be in constant current led driver mode.

Seventh, surge protection

LED surge protection is low, especially against reverse voltage. Strengthening protection is very important. Many LED lights are installed outdoors, and power systems sometimes encounter various surges that cause LED failure.

Eighth, temperature protection function

We should increase the negative feedback output current of the LED temperature to avoid the high temperature of the LED.
