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:
• Power Dissipated (Watts) - Determined by the light
• Ambient Conditions - Ambient temperature, free or
• Thermal Path - Thermal interface material, light
• Desired Lifetime and Lumen Maintenance - Lower
• Desired Light Output - LED luminous output is
Lamina
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.

operate. Red and amber are more affected than

generally help to lower LED operating temperatures
and result in higher light output.

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
are drilled and tapped to accept the recommended
fasteners.
