LED aluminum PCB and FR-4 fiberglass circuit boards belong to PCB. To say differently, only compare LED aluminum substrate with FR-4 fiberglass circuit board.

The LED aluminum substrate is printed on the surface of aluminum material with better thermal conductivity, and then weld electronic components on it.

In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.

The voltage drop across an LED is approximately constant over a wide range of operating current; therefore, a small increase in applied voltage dramatically increases the flow.

Simple circuits are used for low-power indicator LEDs. More complex, current source circuits are required when driving high-power LEDs for illumination to achieve correct, current regulation.

An LED PCB board tends to generate a high volume of heat, making it difficult to cool via traditional means.
