UL LED drive power supply is the key to LED lamps. It is like a person's heart. To manufacture high-quality LED lamps for lighting, you must abandon
constant voltage LEDs.
LED transformer is the best way to drive LEDs. It uses constant current source to drive. There is no need to connect a current-limiting resistor in the output circuit. The current flowing through the LED is not affected by changes in
external power supply voltage and ambient temperature.
And the influence of the discreteness of LED parameters, which can keep the current constant and give full play to the various excellent characteristics of LED.
The LED constant current power supply is used to supply power to the LED lamps. Since the current flowing through the LED is automatically detected and controlled during the working period of the power supply, there is no need to worry about excessive current at the moment of power-on
When the LED flows through, there is no need to worry about short-circuiting the load and burning out the power supply.
Using constant current drive mode, it can avoid the change of LED forward voltage and cause current fluctuation, at the same time, the constant current makes the brightness of LED stable, which is also convenient for LED lamp factory to implement mass production.
To ensure the consistency of products, many manufacturers have fully realized the importance of driving power. Many LED lamp manufacturers have abandoned the constant voltage mode, and chose the higher cost constant current mode to drive the LED lamps.
