With the development of electronic technology, PCB lays a good foundation for a various of electronic products, such as the development of PCB for LED lighting. A prime example is the development of the PCB for LED lighting. The LED is soldered to the circuit board and features a chip that creates the light when 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.
However, it is difficult for an LED PCB board to cool with traditional methods because it tends to create a high volume of heat. So metal core PCBs are often chosen for LED application as their enhanced ability to dissipate heat. Especially aluminum is often used to fabricate 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.
The advantages of LED PCB：
With the electronic products is more and more smaller and thinner, making it popular to use LED PCB, and there are various advantages with using LED PCB as follows:
· Lightweight, low profile
· dimensional stability
· thermal expansion
· heat dissipation
· Lower cost backlit membrane switch
· Dust and moisture resistant
· Make it easy to integrate into complex interface assemblies
· Efficient low power consumption
· Available in a wide variety of sizes, colors, and intensities
· May be used in silver flex membrane switches and copper flex membrane switches.
LED PCB Applications:
The LED PCB lights can be integrated into many lighting applications thanks to their excellent energy efficiency, low cost and maximum design flexibility, such as:
Street tunnel lighting
Photovoltaic (solar) lighting
Flashlights and lanterns
Lights in hospital operating theater
