Not all LED Heatsinks are made equal!

Cooliance provides a range of pin fin forged high-performance passive, and Coolstrate® active, pin fin LED heatsinks for OSRAM LEDs

These heatsinks, from 5W to 500W, offer industry-leading thermal performance, check out the thermal resistance performance in the table below.

OSRAM COB LEDs mount onto the heatsink directly or via an LED Holder. Cooliance will ship each heatsink pre-drilled with mounting holes for your LED/LED holder.

Our technical sales team will match your COB LED, or LED holder, with appropriate Cooliance LED Heatsink providing you with an order number for a heatsink complete with threaded mounting holes.

Passive LED Heatsink for Edison Opto LED Arrays
LED Heatsinks for OSRAM

Coolstrate® is silent and reliable, well-exceeding the life of your light engine

  • Inaudible at one meter
  • No issues of resonance – multiple units mounted together are as silent as a single unit
  • Long-life motor design keeps our units silent for years
  • Coolstrate® fans are designed to operate trouble-free for over 60,000 hours
    • Double-bearing industrial fans, produced in the hundreds of thousands and with proven reliability records
    • Double-bearing fans do not suffer from sudden failure, unlike sleeve-bearing based designs
    • Double-bearing fans are indifferent to orientation, unlike sleeve-bearing based designs
  • Heavy-duty, high-density pin fin heat sinks are designed to eliminate internal dust build-up – our field tests prove it.
  • Robust mounting clip protects the fan from shock and virtually eliminates accidental damage
  • No separate driver is required – you have the full range of choice for the driver that best meets your lighting requirements
  • Easy application testing – with a full range of standard sizes and multiple fan speeds, we make it easy for you to address the trade-offs between size constraints and power
  • Coolstrate®'s 10mm, perfectly flat base gives you maximum security for reliable mounting of your OSRAM array, as well as full freedom in hole placement for mounting points, wire guides and reflector attachments
Active LED Heatsink for Edison Opto LED Arrays

Standard Passive LED Heatsinks are available in the following sizes:

  • Diameters of 20 mm to 160 mm are offered within the standard product family. Consult factory for other sizes.
  • Pin heights of up to 100mm are available

Standard or modified standard solutions - We can provide a solution from our standard product line and model it to ensure that it will provide adequate cooling for your application..

Our precision forge process provides unique advantages for LED cooling:

  • Forging can produce round and other non-linear shapes that are preferred for LED applications.
  • The forge process uses high pressure to form the material and provides control over the grain structure to provide superior thermal performance.
  • LED’s are generally convection cooled and our forged pin fin arrays provide the best possible thermal performance in ambient environments.
  • Heat sinks can be forged in either aluminum or copper.

Custom design services - Our thermal engineers can also work with you to design and model a custom solution optimized to meet the needs of your application.
