DIGITAL MATRIX LED HEADLIGHT SOLUTIONS WITH ULTEM™ RESIN
New technologies such as LED, OLED and laser are rapidly driving new innovations in automotive lighting. Among them, the digital matrix LED headlight is one of the most cutting-edge applications. Based on digital lighting processing (DLP) technology, each headlamp contains about one million micromirrors which disperse the light into tiny pixels and can be adjusted with great precision.
SABIC’s ULTEM™ resin (polyetherimide) addresses high temperature requirements, up to 230°C, for DLP technology. Additionally, the material’s dimensional stability and low outgassing performance are comparable to metal and glass solutions. Potential digital matrix LED headlight applications include the lens barrels, spacers, brackets, reflector mirrors and DMD (Digital Micromirror Device) sockets.
ULTEM RESIN BENEFITS:
- High temperature resistance, haze onset temperature up to 230°C, near-IR transparency for better heat dissipation
- Excellent dimensional stability, low CTE, good creep resistance
- Lightweight solution compared to metal & glass
- Low outgassing to help limit potential risk of headlight contamination
- Direct metallization, primer-free, more environmentally cautious
- Design freedom, high productivity, system cost saving
- Availability of ISCC+ certified bio-based solutions
