TRILUX supports groundbreaking Chronolite research project

TRILUX  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 percent 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.
