Engineered specifically for demanding outdoor and roadway luminaires, this metal core PCB (MCPCB) utilizes an advanced aluminum substrate architecture that combines ultra-low thermal resistance with high dielectric breakdown strength. Designed to house high-power LED arrays and integrated constant-current drivers, the board ensures reliable heat dissipation, minimal lumen depreciation, and long-term durability across wide ambient temperature swings.

Key Features & Benefits

• Enhanced Thermal Management: The ceramic-polymer dielectric layer minimizes thermal resistance ($R_{th}$) between LED junctions and the heatsink, keeping junction temperatures low and extending operating life beyond 50,000 hours (L70/L80).

• High Dielectric Withstand: Formulated to prevent electrical breakdown in humid, high-voltage conditions, providing continuous safety isolation between live circuit traces and the grounded aluminum enclosure.

• Optical Loss Minimization: The specialized white solder mask maintains high optical reflectivity under sustained high-energy blue and near-UV light emissions, avoiding yellowing and preserving total luminaire efficacy (lm/W).

• Smart Streetlight Ready:

  • Optimized footprint layouts for popular LED packages, including SMD 3030, 5050, 3535, and CSP.

  • Dedicated trace routing for 0–10V, PWM, or DALI-2 dimming interfaces, photocell sensors, and radar/PIR motion inputs.

  • Compatible with RF/IoT daughterboards (LoRaWAN, NB-IoT, Zigbee).

Applications

• Municipal roadway and expressway LED luminaire modules

• Tunnel and high-mast industrial floodlighting

• Grid-tied and off-grid solar LED streetlights (12V / 24V / 48V DC topologies)

• Urban parking lot fixtures and pedestrian walkway light bars
