Description

What is LED PCB?

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.

LED  PCB

Now SMD packaging type is the most widely used packaging form in LED applications. In general, it’s limited for the light emitted from a single LED component. So multiple LED components would be used for a single light fixture to achieve sufficient light. Like other semiconductor devices, PCB is the best method to electrically connect the LED components. And a PCB with LED components soldered is usually called as “LED PCB”

Features of LED PCB

  • Make it easy to integrate into complex interface assemblies
  • Efficient low power consumption

Materials Used in LED PCB

There is a number of materials used in LED PCB  are the following:

  • Telecommunications

  • Automotive

  • Computer

  • Medical

LED indicators and displays are always used in telecommunications equipment due to the surrounding machinery, and they have a great heat transfer ability. Therefore, aluminum-based LED PCBs makes a useful effect on their application.

  • Telecommunications

  • heat dissipation

The LED lighting industry

LED lighting or light emitting diode is an increasingly popular lighting solution, so it’s popular to improve longevity and reduce environmental impact. There are some benefits of LED lighting for traditional method

More Efficient:  Traditional incandescent light bulbs release 90 percent or more of their energy as heat. LED lights cut this by up to twenty percent. It means more of your energy is going into lighting your home, and less into unnecessarily heating it.

LED PCB Board Manufactureing

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.
