Solid state lighting Thermal Management

Thermal Conductivity

Why is Cireon’s solid state lighting the longest-lasting in the industry? One reason is our thermally optimized design.

The ability of a Solid State Luminaire to move heat-energy away from the LED is defined by Thermal Conductivity.  Robust thermal conductivity requires:

  • materials of minimal thermal resistance
  • a solid design of components in the conductivity chain
  • optimal interface between the components in the conductivity chain
  • and component geometry that is conducive to the movement of heat-energy 

Die castings are inherently porous, containing air (gases).  Cireon exclusively uses the aluminum extrusion process in the manufacture of our Main Body, creating a much denser product. Competitors using die-cast substrates are limited to running drive currents at less than half of ours to obtain an equivalent LED junction temperature.  (This has been proved by actual in-situ testing.

LED spacing or footprint is another important factor in thermal conductivity. Essentially, the greater the pathway (to the convection surface) that each LED is provided, the less competition for the same molecules to exchange the heat-energy, the less the heat-energy builds up.

Thermally optimized design is just one of the many ways that Cireon assures you the longest-lasting solid state lighting products.
