What is PCB in LED? – An Overview

PCB (Printed Circuit Board) is a crucial component in LED technology. It is a flat, rigid board made from materials like FR4, aluminum, or other composite materials and contains circuits that allow electrical signals to flow throughout the LED lighting system. PCBs play a significant role in ensuring the proper functioning of LEDs by providing electrical connections and mechanical support to the LED components.

In the world of LEDs, PCB serves as the foundation for placing the tiny LED chips. The PCB not only facilitates the power supply but also helps with heat dissipation. Due to the efficiency demands of LEDs, the role of the PCB extends beyond just electrical connections. It ensures thermal management and heat sinking, which are vital for LED longevity and performance.

Key Functions of PCB in LED:

• Electrical Connectivity: PCBs provide the necessary electrical pathways for LED chips to function.
• Thermal Management: LEDs generate heat, and PCBs ensure that this heat is effectively dissipated, preventing the LED from overheating.
• Mechanical Support: PCBs provide mechanical stability to the LED components.
