Lamina is the market leader in super-bright LED arrays, delivering 1W to 100W of super-bright light with exceptional thermal performance and reliability. Applications include architectural lighting, general illumination, automotive, signage, and signaling.
This application note introduces Lamina's super‑bright LED arrays and the proprietary LTCC‑M packaging that enables high luminous output in a compact footprint. It outlines the range of products (1 W‑100 W) and explains why effective thermal design is critical for performance, reliability and safety.
The document provides practical guidance on heatsink selection, thermal interface materials, and thermal‑resistance calculations. It includes example calculations, recommended material values, handling precautions and a list of supplier links to help designers implement reliable thermal solutions for Lamina LED light engines.
| Power range | 1 W to 100 W |
|---|---|
| Light Engine model | BL‑21D0‑0130 |
| Maximum thermal resistance (Light Engine) | 2.9 °C/W |
| Thermal interface tape resistance | 1.0 °C/W |
| Heatsink thermal resistance (example) | 3.8 °C/W |
| Typical power at 12 V | 8.4 W |
| Ambient temperature used in examples | 25 °C |
Lamina LED arrays must be mounted to a properly designed heatsink before operation; the Light Engine case itself is not a heatsink.
The maximum thermal resistance for the BL‑21D0‑0130 Light Engine is 2.9 °C/W.
The 3M 8810 Double Sided PSA Thermal Interface Tape is listed with a thermal resistance of 1.0 °C/W when assembled under the recommended pressure.
Avoid contact with the silicone encapsulant, handle the arrays from the sides, and use ESD protection to prevent damage.
