[2023] The Differences between LED Light Drivers
The differences between different LED light drivers from AVAQ SEMI are mainly in the following areas:
1. Drive mode: LED driver drive mode is divided into constant current and constant voltage two ways. Among them, constant current driver can ensure that the brightness of LED lights equal, constant voltage driver can ensure that the voltage of LED lights equal. Different LED lights need different driving methods, so the choice of driving method is crucial. 2.
2. Current and voltage: The output current and voltage of LED drivers are also different. Some LED lamps have different current and voltage requirements, so the driver must match the electrical characteristics of the LED lamp.
3. Efficiency: the efficiency of the LED lamp driver will also affect the use of the driver with higher efficiency can make the LED lamp more energy efficient and maximize the life of the LED lamp.
4. Dimming performance: some LED light drivers have good dimming performance, you can adjust the brightness of LED lights according to the needs of different scenarios, while other drivers do not have this dimming function.
5. Size and appearance: LED drivers also vary in size and appearance, some drivers may be very small and easy to install, while other drivers may be larger and bulkier.
Overall, the main reason for the differences in LED light drivers is the different needs of the application. In order to choose the right LED light driver for your application, you need to understand the electrical characteristics of your LED light, such as drive method, current and voltage, dimming performance, etc., in order to choose the right driver for you.
How to Read the Parameters on the LED Driver
Common parameters on LED drivers include input voltage, output voltage, output current, power, etc. The following are some common parameters explained:
Input Voltage (Input Voltage): refers to the power supply voltage range that the driver needs to receive in volts (V) or volts of the AC voltage range (such as 100–240V AC).
Output Voltage (Output Voltage): The voltage value of the driver output in volts (V).
Output Current: The current value of the driver output in amperes (A).
Power (Power): refers to the output power of the driver in watts (W), which can usually be calculated based on the output voltage and output current.
PF (Power Factor): refers to the power factor of the drive, usually expressed as a decimal, the closer to 1 means that the higher the power factor.
Efficiency (Efficiency): refers to the driver’s electrical energy conversion efficiency, usually expressed as a percentage, the higher the better the efficiency.
Dimming (Dimming): refers to the dimming mode of the driver, such as PWM, 0–10V dimming, etc.
Protection level (Protection): refers to the protection level of the driver, such as IP20, IP67, etc., indicating that the driver’s dust, water and other levels. It should be noted that when using the LED driver, according to the voltage and current requirements of the LED lights used to select the appropriate driver, and should pay attention to the input voltage range to ensure the use of safe and stable voltage requirements of the site.
How to Determine the LED Driver is Bad
There are several methods that can be used to determine whether the LED driver is bad:
Observe the brightness of the LED light: If the brightness of the LED light becomes weak or flickers, there may be a problem with the driver.
Observe the color of the LED light: If the color of the LED light is not correct, such as turning red or yellow, etc., it may also be a driver failure.
Use a multimeter to test the output voltage and current: Set the multimeter to DC voltage and DC current measurement mode, and connect the red and black meter pens to the positive and negative terminals of the driver in turn to measure whether the output voltage and current are normal.
Measure the input voltage: Use a multimeter or voltmeter to measure whether the driver input voltage is normal. If the input voltage is unstable or too high or too low, it may also lead to driver failure.
Replace other drivers: If the above methods are not to determine the cause of the failure, you can consider replacing other drivers that work properly to the LED light, if the LED light brightness is normal, it means that the original driver is faulty. It should be noted that in order to avoid safety accidents caused by electrical failures, non-professionals are not recommended to disassemble and repair LED drivers by themselves, and should seek professional help.
