LED panel lights have the characteristics of energy saving, environmental protection and long life, so they are very popular in various commercial or workplaces. The led driver power supply of the LED panel light largely determines the use effect and service life of the LED panel light. Therefore, how to choose a suitable panel light power supply is a question worth thinking about. When choosing a power supply for LED panel lights, four factors are mainly considered, namely working current, working voltage, constant current, CE or other certification standards.
1. Working current
The output current of the LED power supply should be about 90% of the rated current of the LED lamp, and cannot exceed this level, otherwise it will affect the life of the LED lamp. And it should not be too low, not lower than 70%, otherwise the brightness of the lamp will be significantly reduced, the output current accuracy is preferably ±5%, the higher the accuracy, the longer the life of the panel lamp.
2. Working voltage
If the voltage of the Led power supply reaches 80% to 120% of the rated voltage, the working efficiency and working quality of the lamp are the highest. If the voltage is too low, it will also cause the lamp to fail to light normally, and the wider the output voltage range of the power supply, the wider the range of power and efficiency.
3. Constant current
Since LED lamps are greatly affected by the environment, choosing a adjustable constant current led driver can ensure that the current remains unchanged during operation. If the current changing in the circuit is too large, it will cause damage to the electrical products.

3. CE certification
Led driver power supply for panel light generally have FCC, American UL and other multi-national certification marks. For example, to distinguish whether the power supply has passed CE certification, you can look at the power input part. The input with filter capacitors and annular common mode inductors is CE certified products. These certifications are professional standards formulated by certification bodies for power supplies according to the technical specifications in the industry, including production process, electromagnetic interference, safety protection, etc. All products that meet certain indicators can only use certification marks on packaging and product surfaces after they have passed the declaration and certification.
