New LUXEON® Altilon SMD-A: The Thinnest, Single-Chip Addressable Package for High Performance, Automotive Forward Lighting

Lumileds’ latest advance package increases luminance, thermal capabilities, and robustness for Front Fog, Low/High Beam and Advanced Driving Beams

Eindhoven, The Netherlands – October 21, 2025Lumileds’ new LUXEON Altilon SMD-A is designed to support today’s most demanding automotive headlighting applications including front fog, low and high beam, and adaptive driving beam (ADB). It is the thinnest single-chip addressable LED. Its package design leverages compatibility with Al-IMS to ensure cost efficient reflow soldering robustness, a Cu-based leadframe for higher thermal capabilities and is fully compatible with metal core PCBs. The unique package increases contrast and luminance and with a Moisture Sensitivity Level of 1, the LUXEON Altilon SMD-A requires no special handling, packaging, or storage to protect it from moisture.

“LUXEON Altilon SMD-A facilitates the highest, optimized performance. Its unique pad layout enables single-die addressability for native bi-function headlighting in a single footprint while maintaining source luminance. These capabilities significantly simplify the lamp architecture for cost-effective, time-to-market solutions,” said Nicolai Duongtran, Product Marketing Manager for Automotive Headlighting at Lumileds.

Optimizing headlighting through package design

The small edges of the LUXEON Altilon SMD-A improve contrast now measuring 1:247 and produce a sharp, natural cutoff. Reducing the gap between light emitting areas to 70µm and achieving the optimal die-to-phosphor size boost luminance for additional cost-performance improvements.

With a z-height of only 433µm, it is the thinnest single chip addressable package which allows for optical structures to be designed with greater accuracy and efficacy. With this advancement, the headlamp system can be optimized as the optics can be designed closer to the LED thereby improving optical efficiency.

Featured in 2026 model-year vehicles
New car buyers will enjoy the benefits of LUXEON Altilon SMD-A as it’s already designed into 2026 model-year vehicles. Lumileds is also using the new LED in its LUXEON LxN L1B Gen3 homologated module. LUXEON LxN modules are standard, “bulb-like” options delivering cost-effective, reliable, lighting options. Their standard interface means supports a minimal design effort and a faster roll out.

Options and Availability
The LUXEON Altilon SMD-A is available in four configurations, a 1×2, a 1×3, a 1×4, and a 1×5 for mass production manufacturing. A new datasheet is available online. Samples are available by contacting Lumileds’ Automotive Team.
