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