UK, January 2025 – TRILUX, a leading innovator in the lighting industry, is proud to be
an associate partner in the Chronolite research project, a pioneering initiative exploring
the impact of Human-Centric Lighting (HCL) on circadian rhythms in mobile
environments. In collaboration with institutions such as TU Ilmenau and Charité Berlin
and funded by the Federal Ministry for Digital and Transport (BMDV), the project aims to
develop an IoT standard for chronobiologically effective lighting across the mobility
sector, including road, rail, transit, and air travel.
Artificial lighting is an ever-present feature of modern life, with people spending approximately
90% of their time indoors. Beyond providing basic illumination, lighting significantly influences
human biological rhythms, mainly through regulating melatonin—the hormone responsible for
sleep. Chronolite is investigating how tailored lighting solutions can better align with individual
chronotypes and support healthier sleep-wake cycles in increasingly mobile societies.
Addressing the Challenges of a 24/7 World
Individuals exposed to irregular sleep patterns—such as shift workers and frequent
travellers—often experience disruptions to their circadian rhythms. Factors such as prolonged
screen exposure, artificial light at night, and time zone changes can contribute to social jet lag
and have adverse health effects. Chronolite seeks to address these challenges by developing
intelligent lighting solutions that support well-being and performance.
A key focus of the project is developing an international IoT standard for adaptive lighting
systems that respond to users' biological needs. This involves creating lighting environments
that adjust dynamically to support daily rhythms in diverse transport settings, such as aircraft
cabins and train compartments. The system will capture and synchronise individual
preferences—such as chronotype (early riser or night owl) and daily patterns—across multiple
mobility scenarios to provide optimised lighting conditions.
Technology Driving the Future of HCL
Achieving such a sophisticated lighting solution requires seamless IoT integration and fast,
stable connectivity. For example, TRILUX's Tunable White luminaires play a crucial role in
adapting lighting to user needs throughout the customer journey. The project also addresses
data protection challenges, ensuring interoperability across different protocols while
safeguarding user privacy.
An exciting development within Chronolite is the CARL system, a prototype that links
controllable lighting units with an IoT connection and the Chronolite app. Initial tests in real-
world environments, such as airports, have demonstrated positive effects on users' attention
and well-being, highlighting the potential of personalised lighting adjustments.
Looking Ahead
The Chronolite project was scheduled to conclude in December 2024 but has been extended
to June 2025 for further refinement. Following its completion, findings from the project could
have far-reaching applications beyond mobility, influencing sectors such as healthcare and
workplace environments.
TRILUX remains committed to shaping the future of Human-Centric Lighting by contributing to
forward-thinking initiatives such as Chronolite, reinforcing its position as a leader in innovative
and sustainable lighting solutions.
