As the market leader in the development and manufacture of super-bright LED light engines, Lamina brings solid state lighting to applications which until now were only possible with traditional lighting sources. Lamina’s LED light engines are manufactured by combining high brightness LEDs from industry-leading LED manufacturers with Lamina's proprietary packaging technology. This technology is a breakthrough in thermal performance for LED packaging, a key factor in determining LED life and reliability. Unmatched thermal performance coupled with package interconnectivity allows Lamina to densely cluster multiple LEDs to achieve exceptionally high luminous intensity in very small footprints. Lamina’s light engines are available in white, RGB and monochrome, from 1W to 100W, and also in custom packages up to 1000W.
The Atlas Series Daylight White LED Light Engine from Lamina is a solid‑state lighting solution offering up to 250 lm from a single point in a 4700 K white output. It is available in white, RGB and monochrome versions from 1 W to 100 W, with custom sizes up to 1000 W, and complies with RoHS standards.
The engine features a round footprint, isolated metal base for series or parallel wiring, integrated 4 kV ESD protection, and optional EZ‑Connect boards for solder‑less integration. Recommended mounting uses conductive epoxy or thermal grease with precise torque, and the device must operate below a junction temperature of 125 °C.
| Forward Voltage (VF) | 7.5 – 8.2 V |
|---|---|
| Test Current (IF) | 750 – 1050 mA |
| Power | 5.27 – 8.61 W |
| Luminous Flux (ΦV) | 175 – 250 lm |
| Thermal Resistance (TR) | 4.0 – 5.5 ºC/W |
| ESD Sensitivity (HBM) | 4000 V |
| Recommended Mounting Torque | 0.89 in‑lb (10 N·cm) initial, up to 4 in‑lb (4.5 N·cm) final |
| Maximum Junction Temperature | 125 °C |
The typical forward voltage is between 7.5 V and 8.2 V.
Tighten each screw to about 0.89 in‑lb (10 N·cm) initially, then to a maximum of 4 in‑lb (4.5 N·cm).
The LED engine must operate at a junction temperature of 125 °C or lower.
A heat sink must keep the junction temperature below 125 °C, with a thermal resistance calculated as (125 °C – Tj(rise) – ambient)/P.
