Optimal Thermal Management

The board incorporates a direct thermal path through a dielectric layer positioned under the LED thermal pads. This design ensures efficient heat dissipation, critical for maintaining the LED’s junction temperature well below its maximum rated value as per LED manufacturer specifications.

Cooling Recommendations

For optimal thermal performance, it is recommended that the PCB be mounted onto a suitable finned heat sink made of aluminium or copper that is exposed to open air. The mounting can be achieved through various methods, including:

• 560mm pressure sensitive, thermally conductive tape (Recommended)
• Thermal Compound: Requires the use of mechanical fasteners

Ensure that both mating surfaces are clean and flat before assembly to maximize heat transfer efficiency.

Mechanical Stability

Mechanical fasteners are recommended to secure the module robustly, ensuring stable and durable mounting. The base of the LED MCPCB is electrically neutral, which eliminates the need for electrical isolation from the cooling surface.

Optics Integration

This PCB is compatible with leading optics solutions from Ledil, Khatod, and Linear Optics, which can be adhered to the PCB using specific adhesives. For detailed assembly instructions, refer to Ledil’s generic guide on LED/optics assembly, available for Download

Electrical Configuration

The PCB features Anode and Cathode pads at its ends, supporting various wiring configurations including standalone setups or grouped in series or parallel arrays, enhancing design flexibility.
