How to choose the LED driver power?

According to the characteristics of grid power consumption, LED and products, when we choose the led driver power, the following points should be considered:

1. High reliability

LED products are mainly composed of LED chips, power supply and heat dissipation enclosures, control circuits, etc., and LED power supply directly affects the quality of the product.

2. High efficiency

LED is an energy-saving product, and the driving power must meet the requirements of energy saving. Therefore, the structure of the power supply installed in the lamp is particularly important. The luminous efficiency of LEDs decreases with increasing LED temperature. The efficiency of the power supply is high, its power consumption is small, the amount of heat generated in the lamp is small, and the temperature rise of the lamp is reduced, which is helpful to delay the lifespan of the LED.

3. Constant current driver mode

In order to match the volt-ampere characteristics of the LED, the LED power supply must use a constant current driver.

4. Surge protection

The impact resistance of the LED is relatively poor, so the input end of the LED drive power supply must have a surge suppression circuit to avoid instant damage to the LED by the switcher.

5. Temperature protection function

In addition to the conventional protection function of the power supply, it is best to increase the LED chip temperature negative feedback in the constant current output to prevent the LED chip PN junction temperature from being too high.

6. LED power life

To improve the life of LED driver power depends on its circuit design. At the same time, the use of higher life capacitors to improve power efficiency, do a good job of heat dissipation, optimize the heat dissipation design of lamps.

7. Working environment

Consider the working environment of LED lamps, such as temperature, humidity, installation location, etc.

8. How the power supply works

In order to better protect the LED, a soft-start circuit needs to be added to avoid voltage spikes at the moment of power-on.
