As we all know, there are two important points in determining the quality of led driver power :

One: look for the brand of capacitors; Ruby (Rubycom Japan) is particularly well-known, Hengying (HY domestic) Wanyu (SAMXON) is more common, of course, the price is a little more than a few dollars than other brand capacitors;

Two: IC control chip; because the IC control chip has short-circuit, over-voltage, overload, over-temperature and other protection functions.

There are three types of driving methods that are currently used in the market. Simply make an analogy:

First, switching power supply

Second, linear Power Supply

There are many linear Power Supplies, and it is also a trend in the future market. The solution has linear ic drive, including segmented, constant current diodes.
1. Linear ic (imported and domestic).
2. Constant current diode
Segmented
The advantage is high efficiency, but in the linear scheme, the cost is the highest, and there is a drawback. When the grid voltage changes, the current of each segment will be different, which will cause the brightness of different segments to be different. The probability is not the same, simply speaking, the brightness is different. One more point is that there are many pins, and the line spacing of the SOP package is small, which will bring trouble to the design and is more limited in use.

Third, the resistance capacity program.
