How mmWave Sensing is Reshaping the Standards of Sleep Health Monitoring

Core Breakthrough: Contactless Precision with mmWave Radar

Sansi has deeply integrated a high-precision mmWave radar sensor into a common household lamp. Through the synergy of miniaturized hardware and customized AI algorithms, it has successfully achieved unobtrusive, continuous vital sign monitoring in home environments.

Privacy by Design, Precision Ensured: The electromagnetic waves emitted by the mmWave radar penetrate the lamp housing. By capturing subtle changes in reflected waves caused by minute chest movements, the system forms a dynamic "vital signs point cloud." AI algorithms analyze this point cloud to calculate parameters like heart rate and respiration with high accuracy. The entire process collects no images, video, or facial information, relying solely on abstract point cloud data processing. This fundamentally eliminates privacy risks, providing users with assured peace of mind.

Unobtrusive Comfort, Stable Reliability: Unlike wearables or PPG sensors requiring skin contact, this technology achieves true non-contact monitoring. It imposes no wearability burden and does not alter user sleep habits. It effectively overcomes the pain points of contact sensors, which are prone to interference from movement or detachment, ensuring all-night data continuity and stability to accurately reflect natural sleep states.

Deep Analysis Focused on Sleep Quality: The product’s true value lies in its professional sleep analysis capability. It goes beyond merely recording sleep duration, utilizing advanced algorithms to continuously monitor and analyze sleep architecture—including deep sleep, light sleep, and REM cycles—while accurately identifying nocturnal apnea and hypopnea events. This offers a convenient and unobtrusive tool for preliminary screening and long-term trend tracking, particularly beneficial for individuals suffering from Sleep Apnea (a condition widely associated with factors such as weight and affecting many worldwide). Moreover, by analyzing Heart Rate Variability (HRV), the product assesses users’ stress recovery levels and autonomic nervous system balance, generating a multi-dimensional sleep quality report.

Technical Reliability Rooted in Rigorous Engineering Validation

Sansi’s ability to robustly integrate cutting-edge sensing technology into consumer electronics stems from its deep global project experience. As a technology company holding over 880 patents in LED display, lighting, and system integration, Sansi products have been deployed in major projects such as the Hong Kong–Zhuhai–Macao Bridge and the Jingxiong Smart Highway. These experiences have honed its core competencies in thermal management, long-term stability, and complex system integration, ensuring that this innovative health monitoring device not only delivers precise data but also meets the reliability and durability required for daily use as a lighting product.

Leading Industry Trends: Redefining the Boundaries of Smart Home Devices

The launch of the Sansi Sleep Monitoring Bedside Lamp signals a clear direction in industry evolution: smart home devices are transitioning from single-function “terminals” into integrated “intelligent nodes” capable of environmental sensing, data collection, and health services. It represents an elevation of industry value—from competing on hardware specifications to providing continuous health insights and personalized service capabilities.

Against the backdrop of deepening integration between global health technology and living spaces, Sansi not only demonstrates its leading position in the convergence of optoelectronic technology and biosensing but also delivers an elegant, effective, and easily accessible solution to the widespread challenge of sleep health management. This lamp illuminates a new gateway toward a more scientific and disciplined approach to healthy living.

Sunlight, UVB and Vitamin D – Human Centric Lighting Beyond Melanopic Stimulation

by Ir. Rémy C. Broersma and Dr. Ir. Marcel P. Lucassen, Scientists at Signify Research Eindhoven UVB radiation initiates vital processes in our body, one of which is the production of vitamin D in the skin. It is well known that over-exposure to the sun may bring a risk. Less well known is that the same is true for insufficient sun exposure due to our indoor lifestyle. In Part 1 of this article, we first describe the scientific understanding behind vitamin D. In Part 2 we describe how artificial light can be enriched with a safe, low dose of UVB, to supplement natural vitamin D production in the skin. Not too much, not too little.

Light in the Service of Health – Bringing the Science of Light and Health into Everyday Life through Evidence-based Communication

Light does far more than let us see. In this episode of the LED professional podcast, Manuel Spitschan and Laura Kervezee, co-chairs of the Light for Public Health Initiative, explain how light acts as the master regulator of the body’s internal clock: it synchronises our physiology with the day outside, shapes mood and alertness, and times the release of melatonin, the hormone that governs sleep. The science is settled enough to act on, so the initiative has distilled it into 26 consensus statements on how light affects the body and well-being, written as practical, evidence-based guidance for individuals, employers, schools and cities. A compact 14-minute briefing on why good light is a public-health question, and what to do about it. Based on the authors’ article in LED professional Review #112.

deLIGHTed Talks #8: Good Light – Good Sleep

Full recording of deLIGHTed Talks #8, held online by LpS DIGITAL on 24 April 2025 (91 minutes). Dr. Renske Lok (Stanford University) shows that bright light during the day deepens nighttime sleep, reduces nighttime awakenings, improves sleep efficiency and lowers next-day sleep inertia. Dr. Jeffrey Hubbard (University of Lausanne / EPFL) compares how light and darkness drive sleep and wakefulness in nocturnal mice and day-active Sudanian grass rats. Chronobiologist Dr. Virginie Gabel, founder of Clock&Me, moderates the session and the discussion on what the findings mean for lighting design.
