LED is an acronym for light emitting diode, which is semiconductor diodes.
The LED is soldered to the printed circuit board and features a chip that creates the light as electrically connected.
A thermal heat sink and a ceramic base are used to bond the chip.
Needless to say, LED PCB is the core of LED lighting, and an LED PCB is easy to create a high volume of heat,
but making it hard to cool with traditional methods.
So metal core PCB is widely used in LED application because of their enhanced ability to dissipate heat,
especially aluminum is often used to fabricate PCB for LED lights.
In general, the aluminum PCB contains a thin layer pf thermally conductive dielectric material that can transfer and dissipate the heat with much greater efficiency than a traditional rigid PCB.
