LED is light-emitting diodes, is a popular technology for lighting in various industries. LED is solid lighting that uses semiconductors to convert electricity into light. Compared to traditional light bulbs, they use up to 80% less energy and last 25 times longer. They also have other advantages like small and environmentally friendly.
As the name suggests, LED PCBs are the PCBs with LED components soldered. PCBs are the physical support of LEDs and feature a chip on the board to produce light when electrically connected. PCBs are the best method to electrically connect the LED components, which can transfer heat away from the LEDs to improve their performance and prevent damage. Metalcore PCBs are widely used in LED applications due to their excellent transfer and heat dissipation efficiency. The aluminum substrate is the most favored metal core PCB for LED application.
What are the advantages of aluminum PCBs for LEDs?
Because LEDs will generate a large amount of heat, there needs an efficient way to remove the heat and protect components. Therefore, the substrate is significant for PCBs in the LED Industry, which helps determine the heat transfer efficiency on boards. Using aluminum substrate is the best solution for a temperature-sensitive application such as LEDs.
Metalcore PCBs are favored by LED PCB designers when thermal conductivity is critical. As one of metalcore PCBs, aluminum base PCB has become the most popular choice for engineers because of its excellent thermal conductivity and high-cost performance. In addition, aluminum also has the characteristics of lightness, thinness, and easy deformation, which can easily meet the needs of different applications.
The factors that need to be considered in LED PCB design
1.Materials
Many LED PCBs use aluminum as the base layer because aluminum substrate works well to remove and dissipate the extra heat. The aluminum PCBs can also satisfy insulating conductors and allow electrical connection between LED components.
2.Trace routing
Proper trace routing prevents open and short circuits, crosstalk between circuits. Proper trace width helps to prevent overheating. A good trace space design and installation hole layout also ensure no problems during the manufacturing process.
3.Thermal management
Thermal management is a crucial aspect of LED PCB design. Poorly controlled temperatures will affect the color purity of the light and shorten the device’s life span. Aluminum substrate and radiators are often the primary considerations in LED PCB design.
The application of LED PCBs
LEDs are the most popular form of lighting in homes, businesses, and industries today because they are more energy-efficient, environmentally friendly, and have lower power consumption and a longer life span. As an integral part of LED lighting, LED PCBs manufacturing and products are constantly increasing t meet the growing demand.
LED PCBs are commonly used in these areas:
Home lighting
Telecommunications
Traffic lights
Camping accessories
Power converters
Automotive industry
Medical industry
Military field applications
ICT and Tech
