Lamina
®
is pleased to offer you these accessories with
our array of award winning LED 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.

election
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
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, 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
®
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:
• Designed for optimal thermal performance with
Lamina’s Atlas
TM
NT-4000 and Titan
TM
NT-5000
families of light engines
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

Lamina’s heat sinks come in four different
thicknesses (“A” Dimension), from 0.5”
(12.7 mm) to 1.5” (38.1 mm) thick. Table 1
lists the applicable sizes for Lamina’s stan-
dard Atlas
TM
NT-4000 products.

Note: 1. For the higher wattage red and
amber light engines additional forced
convection is necessary. Additional
convection can be achieved by attaching
a CPU style fan to the back of the heat
sink, connecting the fan to the paddles of
the heat sink.
Note 2. Applicable heat sinks when
operated at rated LED light engine
power, 25°C ambient and unrestricted
convection.
