Introduce the Working Principle of AC -free LED Module

The current is divided into DC and AC power. The English abbreviation of DC electricity, which is Direct Current; the English abbreviation of AC power is AC, that is, Alternating Current, AC -free LED module, as the name implies, that is, the module that directly connects AC power power. Earlier the structure of the LED lamps is: drivershellDC module. Since 2010, the AC module has appeared, and the structure of LED lamps has a new definition: shellAC module, which not only reduces the LED lamps lamps The manufacturing process has also reduced the cost of lamps. After 10 years of development, it is currently very mature. With the continuous improvement of LED lamp bead technology, the voltage of single lamp beads is getting higher and higher. There are fewer and fewer beads, so the cost of AC module is getting lower and lower. The working principle of the AC module is to directly input the template board through the household electricity (220V or 110V), through the rectification of the rectifier bridge, and then use the high -voltage linear IC and resistance to LED to the LED. All the materials are directly welded in aluminum. On the substrate, the factory is very simple. It only needs to be welded to use it, but because the pressure of the substrate is very important because of the direct high pressure intervention in the substrate, the resistance of this substrate is very important. Generally, it is required to hit the resistance of AC-1750V. The safety of the module must be paid special attention, so many manufacturers now add a lens, or seal it with electronic silicone in the high -voltage part to isolate the possibility of human hands.驱动LED已经相当的成熟由于它的出现是为了取代驱动所以他的功能都是按照驱动来实现的现在驱动能做到的功能AC模组也都能实现了例如调光 Remove Flight, Switching, Switching, Bluetooth, WiFi, etc.
