In Addition To The LED Driving Circuit To Meet The Safety Requirements, The Other Basic Functions Should Have Two Aspects:

- Jul 14, 2017 -

One is to maintain the constant flow characteristics as far as possible, especially when the power supply voltage ±15% changes, should still be able to maintain the output current in the ±10% range change. The main reasons are: 1, to avoid driving current exceeds the maximum rating, affecting its reliability. 2, to obtain the expected brightness requirements, and ensure the brightness of each led, chroma consistency.

The second is that the drive circuit should maintain a lower power consumption, so that the LED system efficiency can be maintained at a higher level.
