Lamina's newest LED light engine delivers 125 lumens of blended RGB light. Lamina’s NT4000 RGB LED light engines have independent color control for dynamic or preset display of
colors. Through additive color mixing there is complete control of up to 16 million colors and various white color temperatures which can be produced.

Lamina NT-4000 LED light engines are configured with a single cavity populated with multiple LEDs. The RGB light engine has red, green and blue LED die arranged for optimal
color mixing within each light engine, a unique feature made possible with Lamina’s packaging technology. The new design incorporates many new features, including:

• ROUND FOOTPRINT FOR DESIGN FLEXIBILITY
• DESIGNED FOR POPULAR DRIVE CURRENTS – 350 MA
• THREE CHANNEL CONTROL WITH INDEPENDENT INPUT/OUTPUT
• INTEGRATED ESD PROTECTION -4,000V HBM
• ISOLATED METAL BASE - MAKES WIRING IN SERIES OR PARALLEL POSSIBLE ON A COMMON HEAT SINK

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 OilBased 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.
