In LED modules, 'substrate' often refers to the base material (e.g., aluminum or ceramic) that provides thermal and mechanical support, while 'PCB' specifically denotes the printed circuit board with etched copper traces for electrical connections. They are commonly used interchangeably, but the substrate is the foundational layer, and the PCB includes the conductive patterning.
Thermal management is critical because LEDs generate heat during operation, which can reduce efficiency, cause color shifts, and shorten lifespan. A Substrate/PCB with high thermal conductivity (e.g., metal-core or ceramic) dissipates heat effectively, maintaining LED performance and reliability.
