While LEDs are shining, LED driver are the top priority in the development of the LED industry chain. The life and reliability of LED driver directly affect the longevity of LED light sources. Therefore, as the LED industry chain continues to integrate and develop, the maturity of LED driver technology plays a decisive role.There are many types and parameters of LED driver. The following is a detailed explanation of its models and parameters:
1. Main parameters of LED driver
Output power: According to the output power, LED driver has 0.4W, 1.28W, 1.4W, 3W, 5W, 8W, 10.5W, 12W, 15W, 18W, 20W, 30W, 45W, 60W, 100W, 150W, 200W, 300W and other specifications.
Output voltage: There are also many output voltages, such as DC4V, 6V, 9V, 12V, 24V, 36V, 48V, etc. The specific choice depends on the needs of LED lights.
Appearance structure: LED driver can be divided into two types according to the appearance structure: PCBA bare board and shell1.
Safety structure: It is divided into isolation and non-isolation. The isolation type converts high voltage into low voltage through a transformer, which is safer.
Power Factor (PF): A high PF power supply is more efficient and can save energy better. There are two types: with power factor correction and without power factor correction.
Waterproof performance: According to the requirements of the use environment, LED driver power supplies can be divided into waterproof and non-waterproof. The waterproof type is suitable for outdoor use.
2. Parameters to consider when selecting LED driver
Power matching: The power of the driver power supply must match the power of the LED lamp. Too high or too low will affect the performance of the lamp. Generally speaking, the rated power of the driver power supply should be slightly higher than the actual power of the LED lamp to ensure long-term stability.
Input voltage range: The input voltage range of the driver power supply should match the actual use environment to avoid lamp failure due to voltage fluctuations. For example, the input voltage range of some LED tunnel lights is AC 85V-265V.
Efficiency and power factor: A high-efficiency driver power supply can not only save energy, but also reduce power consumption and extend the service life of the lamp. At the same time, a high power factor also helps to improve the efficiency of the power supply and the stability of the power grid.
3. Other parameters and characteristics
Excitation mode: There are self-excitation and external excitation.
Circuit topology: There are many types such as RCC, Flyback, Forward, Half-Bridge, Full-Bridge, etc.
Conversion mode: There are mainly two conversion modes: AC-DC and DC-DC.
Output performance: It can be divided into three types: constant current, constant voltage, and both constant current and constant voltage. The specific choice depends on the working characteristics of the LED lamp.
In addition, there are some special LED driver power supplies, such as high-power driver power supplies, which may have special parameters and characteristics, such as short-circuit current, conversion efficiency, power factor, etc. When choosing, it is necessary to make comprehensive considerations based on the specific application scenarios and needs.
