As PCB technology has continued to evolve, it has paved the way for the creation of a host of exciting product innovations. 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 produces the light when electrically connected. A thermal heat sink and a ceramic base are used to bond the chip.
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.
PCB LED Applications
PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy efficiency, low cost and maximum design flexibility. Examples include Automotive headlights, Airport runway landing lights, Lighting used in military field applications, Street lighting, Highway tunnel lighting, Photovoltaic (solar) lighting, Flashlights and lanterns, Traffic and signal lighting, Lighting in hospital operating rooms, High growth plant lighting and many others.
