High Light 6061 aluminum LED heat sink ，±0.01mm tolerance LED heat sink ，Radial fins aluminum cooling base
Custom 6061 Aluminum LED Heat Sink Base
The aluminum LED heat sink housing, also known as LED light source cooling base, is an integrated thermal structural component professionally CNC machined from high-thermal-conductivity 6061 aluminum alloy. Designed with radial radiation fins and outer-wall annular cooling grooves, this one-piece heat sink integrates heat dissipation and mounting functions. The central precision inner bore is reserved for LED beads and optical lens assembly, widely adopted for high-power machine vision lighting and industrial illumination systems.
Key Features
  • High Thermal Conductivity Material: Premium 6061 aluminum alloy, excellent heat dissipation performance, ideal for LED high-power cooling systems
  • Integrated Turn-Mill Machining: One-piece forming by turning and 4-axis milling, no splicing, high structural rigidity and stability
  • Dual Heat Dissipation Structure: Combined radial radiation fins and outer annular grooves to maximize heat exchange area
  • Precision Assembly Structure: High-coaxiality central mounting hole and uniformly distributed counterbore holes for seamless fitting
  • Deformation-resistant Process: Optimized low-feed cutting solves thin-fin vibration and deformation problems
  • Custom Surface Treatment: Support natural or black anodizing for anti-corrosion and upgraded heat dissipation efficiency
  • Flexible Production: Support custom prototype sampling, small-batch trial and large-scale mass production
Benefits
  • Dual fin & groove heat dissipation structure greatly increases air contact area, rapidly taking away LED working heat and avoiding local overheating
  • One-piece CNC forming eliminates assembly gaps, reduces thermal resistance and improves overall heat conduction efficiency
  • Precision coaxiality and position tolerance ensure stable installation of lamp beads and optical groups, uniform lighting effect
  • Anodizing surface treatment improves wear resistance and corrosion resistance, adapting to long-term industrial indoor and outdoor working environments
  • Effectively reduces LED light decay, stabilizes lighting brightness and significantly extends the service life of lighting equipment
  • High structural consistency in batch production, ensuring stable performance of each cooling base
Applications
  • Machine Vision System: Core cooling housing for industrial ring lights, inspection fill lights and visual detection auxiliary light sources
  • High-power Lighting Equipment: Heat dissipation base for outdoor floodlights, stage spotlights and high-brightness industrial searchlights
  • Laser Optical Modules: Heat dissipation cavity for small laser heads and laser emission equipment
  • Medical & Instrument Optics: Cooling structural parts for medical cold light sources and detection instrument lighting components
  • Automation & 3D Scanning: Heat sink for equipment lighting modules and 3D structured light scanning light sources
