Driving Lamina Light Engines
Lamina’s Atlas light engines are designed to operate under current controlled conditions, either constant current, PWM or other current
control methods. The Atlas family is designed to operate using commercially available driver sources from many electronic power
supply companies. Lamina’s Application Engineering team can assist with the proper selection of drivers and can assist with guidance
on your own drive current design.
Assembly Recommendations
Lamina's Atlas Series Light Engines are designed for attachment to a heat sink with conductive epoxy (Arctic Silver Thermal Adhesive
or equivalent), or screw down for flange mount devices with thermal grease (Wakefield Thermal Solutions 120 Series Silicone Oil-
Based Joint Compound or equivalent) in the joint. For attachment using screws, a 2-56 UNC round head or metric equivalent M2 X 0.4
cheese head screw, 18-8 SS is recommended. When mounting the light engine, position the three screws in the center of each of the
three slots. Tighten the three screws evenly, first to about 0.89 inch pounds (10 Newton-centimeter), and then tighten each to a
maximum torque of 4 inch pounds (45 Newton-centimeter). Flatness requirement of the surface that the light engine is mounted to is
0.001 inch/inch (1mm/meter). Thermal tape is not recommended for attachment to heat sinks. When using conductive epoxy to attach
to heat sinks, do not use screws as damage to light source may result.
Heat Sink Recommendations
Lamina LED light engines provide efficient transfer of heat from the individual LED die to a customer supplied heat sink. Lamina’s Atlas
light engines must be operated at or below 125ºC die junction temperature. A heat sink must be attached to the engine with sufficient
cooling capacity to keep the die junction below 125ºC. The temperature rise from the engine base to the die junction may be
determined by calculating the product of the maximum package thermal resistance and the desired operating power level:
The appropriate heat sink may then be approximated
Lamina has developed a selection of radial heat sinks for rapid prototyping of designs with Lamina’s LED Light Engines. Lamina’s heat
sinks are available through select distributors. More information on Lamina’s heat sinks and distributors is available on our website.

Junction Temperature Rise (Tj (rise)) = Operating Power (P) x (Lamina Array Thermal Resistance)
Heat Sink Thermal Resistance (ºC/W) = (125 ºC - Tj (rise) - Maximum Ambient Temperature) / P
*Approximation assumes light engines are screwed down and thermal grease is used as thermal interface material.
