ThermaCool™ Heat Sinks

Lamina ThermaCool Heat Sinks have been sized for each of our standard products and to accommodate a range of desired operating conditions. Proper heat sink sizing is determined by a number of factors, including those listed below:

Power Dissipated (Watts) - Determined by the light engine part number and associated drive parameters chosen for operating the LED Light Engine.

Ambient Conditions - Ambient temperature, free or forced convectionof air, etc.

Thermal Path - Thermal interface material, light engine attachment method, and surface area and conductivity of fixture housing the heat sink.

Desired lifetime and Lumen Maintenance - Lower LED junction temperatures result in longer lifetimes and higher light output over life. Increasing heat sink size will generally help to lower LED operating temperatures.

Desired light output - LED luminous output is affected by the temperature at which the LEDs operate. Red and amber are more affected than blue, green and white. Increasing heat sink size will generally help to lower LED operating temperatures and result in higher light output.

Lamina offers a selection of ThermaCool radial heat sinks to enable easy and rapid prototyping of designs with Lamina light engines. These heat sinks have been designed to maximize the thermal performance of high brightness LED light engines while allowing design flexibility.

Lamina ThermaCool Heat Sinks offer:
   Designed for optimal thermal performance with Lamina’s Atlas and Titan Series of light engines
   Radial Shaped for design flexibility
   Drilled and tapped for ease of assembly
   Anodized for enhanced thermal performance
   Designed for a wide range of mounting positions
