Electrical Connections
LED light engines are available with or without Lamina’s EZConnect board. EZConnect adapter boards have
AMP connectors for solderless connections to Lamina’s wiring harness.
As with many electrical devices, non-acid 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 Drive Current for no more
than two seconds without heat sink.
1. Optical and electrical specifications are given for the specified drive @ 25ºC junction temperature.
2. 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.
Assembly Recommendations
Lamina’s Series Light Engines are designed for attachment to a heat sink with conductive epoxy, or screw down
for flange mount devices with 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).
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.
Receiving Parts and Packaging Trays
Your parts will arrive in either custom fitted trays or on easy to use tape and reel packaging. This packaging
was designed to provide the necessary protection during shipment and to take up the least amount of space in
your storage area.
Notes
1. This product uses 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.
2. Ray trace models are available upon request.
3. Lamina may make process or materials changes affecting the performance or other characteristics of our
products. These 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.
4. All specifications are based on mounting the LED array to a heat sink using the specified hardware and
thermal grease Wakefield P/N 120. The heat sink must meet the specified flatness requirement. Mounting
using screws and thermal tape may damage the device.
