Introducing Lamina’s Light Engine Accessories
Lamina Ceramics is pleased to offer you these accessories with our award winning LED array products. These parts
have been carefully chosen and developed to work with our LED light engines to help you quickly prove out your
design and even go to market if you find them appropriate. Our application engineers are ready to help you select
the right parts for your project. Please do not hesitate to give us a call as we are eager to work with you.
Heat Sink Selection
Lamina’s light engines should maintain LED die junction temperatures at or below maximum rated temperatures.
Lamina’s LED light engines provide very efficient transfer of heat from the individual LED die to the heat sink.
Additionally, a heat sink with sufficient cooling capacity must be selected to maintain the LED die junction below
the maximum rated temperature. Lamina’s heat sinks have been sized for Lamina’s 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:
•
•
•
•
•
Lamina, working in cooperation with ThermaFlo (www.ThermaFlo.com), developed a selection of radial heat sinks
to enable easy and rapid prototyping of designs with Lamina’s light engines. These heat sinks have been designed
to maximize the thermal performance of high brightness LED light engines while allowing design flexibility.
Lamina heat sinks are:
•
• Radial Shaped for design flexibility
•
•
•
Assembly Recommendations
Lamina’s light engines are designed to attach to heat sinks using screws
with thermal grease in the joint or by using conductive epoxy. All Lamina
heat sinks are drilled and tapped to accept the recommended fasteners.
More information on recommended attachment methods can be found
in Lamina’s Connection Guide for Lamina’s LED Light Engines at
www.laminaceramics.com.
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. 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.
