What Is the Driver of the Led Light

What is the driver of the led light? I believe many people have heard of LED lights and don't know much about its importance and function. Today, dimmable led driver suppliers will come together to spread common sense.LED is a solid-state light source. When a forward voltage is applied to both ends of the LED, the minority carriers and the majority carriers in the semiconductor recombine, and the excess energy emitted will cause photon emission.

Different materials can be used to make LEDs with different colors. LED is a kind of light-emitting diode. In addition to its light-emitting characteristics, it also has the characteristics of ordinary semiconductor rectifier diodes.If a lighting fixture is likened to a girl, light distribution is her connotation, structure is her appearance, and electronics is her heart.

Human beings have no heart and no life, and the role of power in the entire lamp is as important as the human heart. A good driving power can also determine the life of a lighting product.Why do LEDs drive?1. LED lamps cannot directly use the normal mains grid voltage.

Due to the characteristics of LED light sources, in order to meet the special voltage and current requirements of LEDs, specially designed voltage conversion equipment must be used to make LEDs work properly, so LEDs The lamp has a power driving method different from the traditional lamp.Driving method of LED lamp power supply:Constant current led driver led driver:a. The output current of the constant current drive circuit is constant, but the output DC voltage changes within a certain range with the size of the load resistance.

The smaller the load resistance, the lower the output voltage. The higher the voltage.b. The constant current circuit is not afraid of short circuit of the load, but it is strictly forbidden that the load is completely open.c. The constant current drive circuit is ideal for driving LEDs, but the price is relatively high.


Attention should be paid to the maximum withstand current and voltage value, which limits the number of LEDs used.Regulated driving power:a. After the parameters of the voltage stabilization circuit are determined, the output voltage is fixed, but the output current changes with the increase and decrease of the load.c. The voltage stabilization circuit is not afraid of the load being open, but it is strictly forbidden that the load is completely short-circuited.


The LEDs are driven by a voltage-stabilized driving circuit. Each string needs to be added with a suitable resistor to make each string of LEDs display an average brightness.The role of LED driver:LED driving power is the key to LED lamps.

It is like the heart of a person.

To make high-quality LED lamps for lighting, it is necessary to abandon the constant voltage mode to drive LEDs. Constant current source driving is the best LED driving method. Using constant current source driving, there is no need to connect a current limiting resistor in the output circuit, and the current flowing on the LED is not affected by changes in external power supply voltage, ambient temperature, and discrete LED parameters.

Influence, so that the current can be kept constant, and the various excellent characteristics of the LED are fully utilized.Constant Current Led Driver Led DriverETL LED driver is used to supply power to the LED lamps. Since the current flowing through the LED is automatically detected and controlled during the power supply operation, there is no need to worry about excessive current flowing through the LED at the moment of power on, and it is not necessary to Worry about short-circuiting the load and burning the power supply.

Adopting constant current driving method, it can avoid the change of current caused by the change of LED forward voltage, meanwhile, the constant current makes the brightness of LED stable, and it is also convenient for LED lamp factory to ensure the consistency of products when mass production is implemented, so many manufacturers have already Fully aware of the importance of driving power, many LED lamp manufacturers have given up the constant voltage method and chose a slightly more expensive constant current method to drive the LED lamps
