LED PCB Board Introduction
LED PCB has many other names, such as LED PCB Board, LED circuit, LED Circuit Board.
LED circuit board is a kind of Printed Circuit Board. Both LED aluminium PCB and FR-4 fiberglass circuit board belong to PCB. To say differently, only compare LED aluminium substrate with FR-4 fiberglass circuit board. LED aluminium substrate is printed on the surface of aluminium 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 greatly increases the current. Very 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. Consequently, metal core PCBs are frequently chosen for LED application due to their enhanced ability to dissipate heat. Aluminum in particular is often used to manufacture circuit boards for LED lights. The Aluminum PCB typically includes a thin layer of thermally conductive dielectric material that can transfer and dissipate the heat with much greater efficiency than a traditional Rigid PCB.
LED generates more heat compared with other electronic parts, which need the PCB to dissipate heat very well. For this special character, Metal Core PCB is frequently used on LED Circuit Board, especially Aluminum Core PCB. The LED Aluminum PCB typically includes a thin layer of thermally conductive dielectric material that can transfer and dissipate the heat with more efficiency than Rigid PCB.
Applications of LED PCB
PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility.
