Description

Technical field [0001] The invention relates to the field of LED driving, in particular to an intelligent LED constant current control power supply device. Background technique [0002] With the development of lighting technology, LED lighting technology has been widely used in production and life due to its advantages of energy saving, environmental protection and long life. [0003] LED is a semiconductor light emitting device that converts electrical signals into optical signals. It has forward conduction, reverse cut-off and overvoltage breakdown characteristics. The brightness of the LED lamp should be selected according to the purpose to determine the power driving mode of the LED power supply. The driving power supply should meet the requirements of energy saving, green economy and high efficiency. Energy saving is reflected in the low power consumption of the driving power supply; green economy is reflected in the higher power factor of the driving unit; high efficiency i...
