Bridgelux and Lumitech Announce Strategic Patent Cross-Licensing Agreement for Next-Generation Tunable White + Color Mixing by RGBW Technology

Fremont, CA and Jennersdorf, Austria – December 3, 2025 – Bridgelux, Inc., a leading developer of high-performance LED lighting solutions, and Lumitech GmbH, the pioneer of tunable white by RGB (PI-LED) technology, today announced a comprehensive patent cross-licensing agreement focused on advanced tunable white solutions using RGBW and RGB-based architectures.

Under the agreement, the two companies license each other to certain respective patents covering tunable white lighting achieved through multi-channel color mixing and proprietary phosphor technologies. The partnership is based on Bridgelux’s leadership in LED lighting technology and Lumitech’s more than 15 years of expertise in white CCT tunable fixtures and  PI-LED technologies.  The cross-license unites Bridgelux’s patents for industry-leading four-color-in-one RGBW packages—including direct-emission and phosphor-converted LEDs—with Lumitech’s foundational PI-LED patents.

Key benefits of the cross-license include:

•  Accelerated innovation and wider adoption of fully tunable white light solutions spanning 1800K to 12000K along the black-body locus (BBL), with constant CRI >90 and efficient lumen output across the entire tunable CCT range

•  A significantly simplified IP landscape for manufacturers developing next-generation human-centric, architectural, and horticultural lighting

• Freedom-to-operate for both companies when implementing tunable white lighting using RGBW or RGB architectures covered under the cross-licensed patents

•  Greater design flexibility with exceptional color rendering (CRI 95+) white light, wide color gamut mixing range, precise circadian stimulus, higher luminous efficacy, and spectral continuity that closely replicates natural sunlight, or adjustable lights with different red and blue ratios for different plant growth.

“This partnership with Lumitech is a game-changer for the tunable white plus RGB color lighting solutions.  By cross licensing our complementary patent portfolios, we are eliminating barriers and empowering customers to bring superior combinations of wide color gamut and white CCT tunable on BBL lighting solutions to market faster and more cost-effectively than ever before,” said Yi-Qun Li, CEO of Bridgelux.  Stefan Tasch, CEO of Lumitech, commented: “Since launching PI-LED in 2008, our goal has been to bring dynamic, black-body-locus-accurate tunable sunlight indoors. Teaming up with Bridgelux allows us to push the boundaries of spectral quality and luminous efficacy even further, solidifying a new global standard for biologically effective, emotionally engaging, and energy-efficient tunable white lighting.”

The agreement is effective immediately. Companies interested in purchasing licensed RGBW lighting solutions or licensing RGBW technology should contact Bridgelux or Lumitech.
