The LED light engines are available with or without Lamina’s EZ-Connect Board. EZ-Connect adapter boards have
AMP connectors for solderless connections to Lamina’s wiring harness.
As with many electrical devices, RMA type solder flux should be used to prepare the solder pads before application of
solder. Ensure proper strain relief of wires attached to the light engine to prevent damage to the light engines solder
pads. For more information refer to Lamina’s Connection application note AN-05 which can be found on the website
at www.laminalighting.com.
Functional test: Parts may be tested using a constant current source set at 25% of specified drive current specified
per specification, drawing or datasheet for no more than two seconds without heat sink. Voltage compliance of power
source should not exceed forward voltage plus 5 volts.

Lamina’s Light Engines are designed for attachment to a heat sink with conductive epoxy or thermal grease 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).

Your parts will arrive in either custom fitted trays or bulk packaging when appropriate. This packaging was designed
or specified to provide the necessary protection during shipment and to take up the least amount of space in your
storage area.

Optical and electrical specifications are given for the specified drive @ 25ºC junction temperature.
When using constant current LED drivers with high compliance voltage (Advance, LEDworks, etc. or a custom
driver) the output of the supply must be connected to the part before power is applied to the input of the
supply.
These products use silicone materials for superior optical performance. Do not expose the part to fluids that
may react with silicone compounds. See Dow Chemical Form 45-0113D-01, Silicone Fluid Resistance Guide.
Ray trace models are available upon request.

products. The products supplied after such changes will continue to meet published specifications, but may
not be identical to product supplied as samples or under prior orders.
All specifications are based on mounting the LED array to a heat sink using the specified hardware and
thermal grease (e.g. Wakefield P/N 120). The heat sink must meet the specified flatness requirement.
Mounting using screws and thermal tape may damage the device.
