Want to use the least money to buy the best products, we hope so, but the real people who buy into are rarely, they have no way to really find the best products with the most reasonable price. In the purchase of an extension of LED merchandise like triac dimmable led driver as well.

LED, everyone is familiar with, when we look up at the huge screen is performed by the LED with the LED driver. After AC power supply, AC variable DC their needs. Get a DC power supply from AC, we first have to be rectified, but was rectified output voltage is half sine wave, so a simple way is a shunt capacitor at the output. It will keep up the charge, which is filtering. For less demanding load on the power fluctuations, as long as the filter on the list, but for voltage requirements, to reach the battery voltage circuit similar in nature, the filter would not, and must regulator.

LED drive circuit in addition to meet safety requirements, should also have two other basic functions, one as much as possible to maintain constant current characteristic, especially in the power supply voltage of ± 15% fluctuation, should be able to keep the output current at ± 10% Changes within range. Second, its power consumption should be kept low, so as to make the system efficient LED is maintained at a high level.

"Steady flow" and "constant" in some electronic circuits, because of a need, we want to provide a constant steady current, rather than the stable voltage thereto, and thus a "constant power supply." But there is a class member, it does not allow a current greater volatility, which is not overcurrent, however, it can also be a smaller current work, such as LED is such a component. At this time we only have to provide it with virtually no current volatility on the line, this move does not filter the current source is called "steady flow sources," such current or a current become such current is called a "steady flow."

In summary, the larger the impedance of the current limiting device, supplied to the LED drive current condition as possible. But such elements should have to bear their own partial pressure is high, but the power consumption is small features, or will have a high efficiency LED power driver circuit because the work is too leaving the overall system efficiency greatly reduced, there is contrary to the purpose of energy efficiency. So it should be capacitive, inductive or active switching power supply, such as efficient power supply resistance or replace the series regulator power supply as LED drive current limiting primary circuit, so as to ensure efficient LED systems.

Using tandem integrated constant power output circuit, it can make the LED light output remains constant over a wide power range, but generally leaving the IC will therefore decrease efficiency. So the use of active switching circuit can ensure a constant output power supply voltage to achieve a significant change in the high conversion efficiency of the power.
